ChatGPT answers, unedited

If you’re a small ecommerce store and budget is the priority, I’d narrow it to Brevo, Omnisend, and Shopify Email rather than jumping straight to something expensive like Klaviyo.

Pricing/features change, but current 2026 comparisons put them roughly here: Shopify Email includes 10,000 free emails/month, Brevo starts around $9/month and is based largely on sends, while Omnisend has a free tier and paid plans starting around $16/month. Shopify Omnisend

My practical shortlist

What I'd choose

If you're on Shopify and have <1,000–2,000 subscribers: I'd start with Shopify Email or Omnisend.

If you have a larger list but send relatively few newsletters: Brevo is particularly interesting because its pricing model is based on sending volume, which can be advantageous when you have lots of contacts but don't email them constantly. Tajo SMTPedia - Everything Email

If automated ecommerce sequences are the main thing you care about: I'd lean toward Omnisend. It has ecommerce-specific workflows such as abandoned cart, post-purchase, product recommendations, and segmentation, rather than treating your store like a generic mailing list. Omnisend

I wouldn't start with Klaviyo solely because it's popular. It's powerful, but if you're watching every dollar, you can get a lot of mileage from a cheaper platform before you need its deeper data/segmentation capabilities. Current comparisons put paid Klaviyo plans around $20/month at the lower end, versus free/low-cost alternatives. toolradar.com Omnisend

The automations I'd set up first

Regardless of platform, I'd prioritize:

1. Welcome sequence — 2–3 emails
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank-you → usage/help → review/cross-sell
4. Win-back — target customers who haven't purchased for a while
5. Newsletter/promotional campaigns

Those flows will generally matter much more than having a fancy newsletter editor.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Etsy, etc.), your approximate subscriber count, and how much you want to spend per month, I can narrow this down to the most economical setup for your particular store.

For a small ecommerce store on a tight budget, I’d narrow it to three:

Current 2026 comparisons generally put MailerLite and Brevo among the strongest budget options, while Klaviyo is more specifically built around ecommerce data and behavioral automation. Shopify iTechGuides

My practical recommendation

Start with MailerLite if you're early-stage and want to spend as little as possible.

It can handle the core system you actually need:

• Newsletter/broadcast emails
• Welcome sequence
• Abandoned-cart emails
• Post-purchase follow-up
• Re-engagement/win-back sequences
• Basic segmentation
• Ecommerce integrations

MailerLite's current free/low-cost tiers make it particularly attractive for a small list, and its automation capabilities cover the fundamental ecommerce sequences. Small Mail Hub MailerLite

Choose Brevo instead if you expect your subscriber list to get large but don't send constantly. Its pricing is based more heavily on email volume rather than simply the number of contacts, which can make a big difference for ecommerce businesses with lots of dormant customers. Axis Intelligence BestSends

Choose Klaviyo if your store's marketing depends heavily on customer behavior—products viewed, purchases, order value, repeat purchases, etc. That's where its deeper ecommerce integration becomes valuable. But I'd avoid paying for it prematurely if your list is tiny and your automation needs are basic. Klaviyo

If I were setting up a $0–$30/month stack

I'd do:

MailerLite → newsletter + basic automations

Then set up these four sequences first:

1. Welcome: 3 emails over ~5–7 days
2. Abandoned cart: 2–3 emails
3. Post-purchase: thank-you → usage/value → review/reorder
4. Win-back: customers who haven't purchased in ~60–120 days

Don't build 20 complicated automations right away. Those four cover a surprisingly large portion of the useful lifecycle messaging for a small store.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Etsy, etc.), roughly how many subscribers you have, and your monthly email budget, I can tell you which of the three makes the most financial sense and what I'd set up first.

If you’re a small ecommerce store and budget is the priority, I’d shortlist Brevo, Omnisend, and Klaviyo—but I’d pick differently depending on your list size and how sophisticated your automations need to be.

My pick: Omnisend

For ecommerce specifically, omnisend.com is probably the best balance of price + ecommerce automation right now.

• Free plan: up to 250 contacts / 500 emails per month.
• Paid Standard starts at $16/month.
• Includes ecommerce-focused automations such as welcome sequences, abandoned cart, post-purchase, order/shipping emails, segmentation, and product recommendations. Omnisend Help Center Omnisend
• It integrates the ecommerce stuff into the email workflow rather than making you build everything from scratch.

I'd choose Omnisend if your primary goal is “send newsletters and automatically turn shoppers into repeat customers.”

Best absolute budget option: Brevo

brevo.com is worth considering if your list is growing but you're still extremely cost-conscious.

Its free plan allows 300 emails/day, and the Starter plan begins at $9/month. Its pricing is based substantially on email volume rather than simply charging more as your contact database grows. Brevo Help

I'd choose Brevo if you're sending relatively infrequent newsletters and want to keep your monthly bill very low.

Best if you expect to get serious about email: Klaviyo

klaviyo.com is the one I'd consider if email is going to become a major sales channel for you.

It's particularly strong for sophisticated customer segmentation, ecommerce data, revenue attribution, and complex flows. But it's harder to justify when you're tiny and watching every dollar. Its free tier currently covers up to 250 profiles and 500 email sends/month. Klaviyo

What I'd avoid initially

Mailchimp is perfectly usable, but for an ecommerce-first business on a tight budget, I don't think it's the strongest choice anymore. Its current pricing/features make more sense if you have a particular reason to prefer its ecosystem. Mailchimp

The setup I'd use

Don't overcomplicate this. Start with 5 automated flows:

1. Welcome series — 2–3 emails after signup
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank you → usage/help → review
4. Win-back — automatically target customers who haven't bought in 60–120 days
5. Product follow-up — recommendations/cross-sells based on what they bought

Then send 1–2 newsletters per week.

That will get you dramatically more value than paying for a sophisticated platform and building 30 elaborate automations nobody has thought through.

If you tell me your ecommerce platform (Shopify, WooCommerce, Squarespace, etc.), roughly how many customers/email subscribers you have, and what “tight budget” means ($0, <$20/mo, <$50/mo, etc.), I can tell you exactly which one I'd use and what plan to start with.

Best if you expect to get serious about email: Klaviyo

klaviyo.com is the one I'd consider if email is going to become a major sales channel for you.

It's particularly strong for sophisticated customer segmentation, ecommerce data, revenue attribution, and complex flows. But it's harder to justify when you're tiny and watching every dollar. Its free tier currently covers up to 250 profiles and 500 email sends/month. klaviyo.com

Mailchimp is perfectly usable, but for an ecommerce-first business on a tight budget, I don't think it's the strongest choice anymore. Its current pricing/features make more sense if you have a particular reason to prefer its ecosystem.

The setup I'd use

Don't overcomplicate this. Start with 5 automated flows:

If you’re a small ecommerce store on a tight budget, I’d narrow it to three:

1. Brevo — best budget pick
2. Omnisend — best ecommerce-specific value
3. Klaviyo — best if you’re already growing quickly

My pick: Brevo

brevo.com is probably where I’d start if keeping costs low is the priority. Its pricing is largely based on email volume rather than the size of your contact database, which can be a big advantage as your list grows. It has a free tier with daily sending limits and paid plans starting around $9/month. Omnisend StacksVerdict

You can use it for:

• Weekly/monthly newsletters
• Welcome sequences
• Abandoned-cart emails
• Post-purchase emails
• Win-back campaigns
• Segmentation
• Basic SMS/WhatsApp messaging

If you're on Shopify: consider Omnisend

omnisend.com is the one I'd choose if you want ecommerce automation without having to build everything yourself. It has native ecommerce integrations and prebuilt workflows for things like abandoned carts, welcome series, post-purchase messaging, and product recommendations. Its free plan is limited, with paid plans starting around $16/month. Omnisend Omnisend

I'd pick it over Brevo if automation is more important than squeezing every last dollar out of the software cost.

Don't start with Klaviyo unless you need it

klaviyo.com is arguably the strongest ecommerce option, particularly for Shopify stores, because of its deep customer/event data and segmentation. But paid pricing starts around $20/month at the small-list level, so I wouldn't pay for it prematurely. Toolradar Omnisend

Once you're doing enough sales that sophisticated segmentation and revenue attribution matter, Klaviyo becomes much more compelling.

What I'd do in your shoes

Shopify Email is particularly interesting if you're on Shopify: Shopify currently includes 10,000 free marketing emails/month, then charges per additional 1,000, making it extremely cheap for basic newsletters. Shopify

My recommendation: start with Brevo if you're very cost-sensitive, or Omnisend if you're on Shopify and want good automated ecommerce flows out of the box. Don't overbuy software before you have enough customers to benefit from advanced segmentation.

If you tell me (1) Shopify/WooCommerce/etc., (2) roughly how many subscribers you have, and (3) your monthly revenue, I can tell you exactly which one I'd choose and what your first 5 automated sequences should be.

For a small ecommerce site on a tight budget, I’d usually narrow it down to three choices:

My top pick: Brevo — best budget option

brevo.com

Best if: you’re early-stage, watching costs, and need newsletters + basic automations.

Why I like it for a small store:

• Lower-cost entry point than many ecommerce-focused tools
• Good for: - Welcome email sequences
• Discount campaigns
• Customer follow-ups
• Basic segmentation
• Transactional emails
• Pricing is often attractive for businesses with larger lists that don’t email constantly because it emphasizes sending volume rather than only contact count. SoftwareInspect StacksVerdict

Set up these automations first:

1. New subscriber → welcome series (3 emails)
2. Abandoned cart reminder
3. Post-purchase thank you + review request
4. Win-back email after 60–90 days

Best if you’re on Shopify and want to grow: Klaviyo

klaviyo.com

Best if: email will become a major sales channel.

Advantages:

• Built specifically around ecommerce data
• Excellent Shopify/WooCommerce integrations
• Strong customer segmentation
• Better revenue tracking from flows
• Great abandoned cart, browse abandonment, and post-purchase sequences Choose My Stack BestSends

Downside:

• Costs can climb as your subscriber list grows. Toolradar

My rule:

• Under ~$5k/month revenue: don’t rush into Klaviyo unless you’re serious about email.
• Growing brand with repeat customers: Klaviyo often becomes worth it.

Easiest beginner option: Mailchimp

mailchimp.com

Best if: you want something simple and familiar.

Pros:

• Easy newsletter creation
• Lots of templates
• Good for occasional campaigns

Cons:

• Ecommerce automation is not as deep as Klaviyo’s, and many stores eventually outgrow it. SoftwareInspect

What I’d choose by situation

For most small ecommerce owners trying to keep expenses low, I’d start with Brevo, build the essential flows, and only move to Klaviyo once email revenue justifies the extra cost.

If you tell me:

1. your ecommerce platform (Shopify, WooCommerce, Etsy, custom site, etc.),
2. your monthly order volume, and
3. your current email list size,

I can give you a more specific recommendation.

For a small ecommerce store on a tight budget, I’d narrow it to three choices:

🥇 I'd start with MailerLite

MailerLite is unusually good for the money. Its free plan currently gives you 250 subscribers and 2,500 emails/month, plus campaigns and 3 automations. Paid plans start at $12/month and add substantially more automation capability. MailerLite MailerLite

For a small ecommerce business, I'd build these flows first:

• Welcome series: 3 emails over ~5 days
• Abandoned cart: 2–3 emails
• Post-purchase: thank-you → product education → cross-sell
• Win-back: email customers who haven't purchased in 60–90 days
• Newsletter: 1–4 campaigns/month

That gets you most of the revenue-producing automation without paying for a sophisticated enterprise platform.

🥈 Brevo if email volume is your biggest concern

brevo.com is particularly attractive if you have a growing list but don't want your bill to explode with subscriber count.

Its free plan allows 300 email sends per day, and its Starter plan begins at $9/month. Standard starts at $18/month and includes unlimited marketing automation. Brevo Help

I'd choose Brevo over MailerLite if you're thinking:

"I have several thousand contacts, but I'm still sending relatively modest campaigns."

🥉 Klaviyo if ecommerce automation is your priority

klaviyo.com is the one I'd eventually consider if your store becomes heavily dependent on email revenue.

It's much more ecommerce-centric: behavioral segmentation, purchase history, revenue attribution, sophisticated flows, etc. But the free tier is only 250 profiles / 500 emails per month, so you'll hit its limits quickly. Klaviyo SG Klaviyo Help Center

I wouldn't start there just because it's "the best ecommerce platform." If you're watching every dollar, the extra sophistication may not pay for itself yet.

My recommendation

If you told me nothing else about your business, I'd do:

MailerLite → build the 5 flows above → spend $0–$12/month initially → move to Klaviyo later if email becomes a major revenue channel.

One important caveat: your ecommerce platform matters. Shopify, WooCommerce, Squarespace, etc. have different integrations and capabilities, and that could change my recommendation.

If you tell me what platform your store runs on (Shopify/WooCommerce/etc.), roughly how many subscribers you have, and how much you're willing to spend per month, I can tell you exactly which one I'd pick and what I'd set up first.

If you're running a small ecommerce store and watching every dollar, I’d narrow it down to three:

🥇 I'd start with Brevo

Brevo is particularly attractive when you're on a tight budget because its pricing is primarily based on emails sent rather than number of contacts. Current comparisons put its entry paid tier around $9/month, with a free tier available. SMB Compare Kurums | Business Intelligence

That can be a big deal if, for example, you eventually have 5,000 subscribers but only send 2–4 campaigns per month.

You can build sequences such as:

• Welcome email → 0 days
• "Here's your discount" → 1 day
• Product education → 3 days
• Social proof → 5 days
• Last-chance offer → 7 days
• Post-purchase thank-you
• Review request
• Re-engagement/win-back

One caveat: Brevo's cheapest tier has limitations around automation, so make sure the plan you're considering includes the workflows you want. Best Firms

🥈 MailerLite if you want dead-simple

MailerLite is probably what I'd choose if your priority is "I don't want to spend my weekend learning email software."

It's inexpensive, has a clean editor, newsletters, forms, segmentation and automation. Current 2026 pricing comparisons put its entry paid plan around $10/month, although its free allowance has become considerably smaller than it used to be. Drip SMTPedia - Everything Email

For a tiny store with a few hundred subscribers, it's a very reasonable starting point.

🥉 Klaviyo when ecommerce automation becomes important

If you're on Shopify/WooCommerce and expect email to become a meaningful sales channel, Klaviyo is the one I'd eventually consider upgrading to.

It's much more ecommerce-native: customer/order behavior, abandoned carts, post-purchase flows, product-based segmentation, etc. Multiple 2026 comparisons still rank it as the strongest ecommerce-specific option. TechSifted Shopify

The downside is cost: you're paying for the sophistication, and it becomes substantially more expensive as your contact list grows. TechSifted

What I'd do in your shoes

If you're under ~1,000 subscribers and cash is tight:

Start with Brevo or MailerLite → build your core automations → don't worry about Klaviyo yet.

I'd prioritize these five automations before spending money on fancy features:

1. Welcome sequence — 3–5 emails
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank you → usage tips → review
4. Win-back — customers who haven't bought in 60–120 days
5. Regular newsletter — roughly 2–4×/month

Those will generally matter much more than having the "best" email platform.

If you tell me (1) Shopify/WooCommerce/etc., (2) roughly how many subscribers you have, and (3) what you can afford per month ($0, $10, $20, etc.), I can tell you exactly which one I'd pick and what plan I'd use.

🥉 Klaviyo when ecommerce automation becomes important

If you're on Shopify/WooCommerce and expect email to become a meaningful sales channel, Klaviyo is the one I'd eventually consider upgrading to.

For a small ecommerce store on a tight budget, I’d narrow it to MailerLite, Omnisend, and Brevo. My pick depends on how ecommerce-heavy your automation needs are.

My recommendation

🥇 Best overall for a tight budget: mailerlite.com

MailerLite is probably where I’d start if you primarily need:

• Weekly/monthly newsletters
• Welcome sequences
• Abandoned-signup/welcome automations
• Post-purchase emails
• Basic segmentation
• A clean, easy email builder

Its free plan currently allows 250 subscribers and 2,500 emails/month, with 3 automations. Paid plans add substantially more automation capability. MailerLite MailerLite

🥈 Best specifically for ecommerce: omnisend.com

I'd choose Omnisend over MailerLite if your store depends heavily on automated ecommerce flows such as:

• Abandoned cart
• Browse abandonment
• Post-purchase follow-ups
• Product/revenue-based segmentation
• Customer win-back
• Email + SMS

Its current free plan supports 250 contacts and 500 emails/month; Standard starts at $16/month, with a current introductory discount bringing the first three months lower. Omnisend Help Center Omnisend

🥉 Best if you want lots of contacts without paying based primarily on list size: brevo.com

Brevo's free plan stores up to 100,000 contacts, although you're limited to 300 email sends per day. Its paid Starter plan starts at $9/month, while more advanced automation is included in Standard starting at $18/month. Brevo Help

What I'd not start with

klaviyo.com is excellent for ecommerce, and I'd consider it once you're generating enough sales to justify sophisticated segmentation and revenue attribution. But its free tier is currently only 250 profiles / 500 emails per month, so I wouldn't choose it purely because it's the "industry standard" when you're watching every dollar. Klaviyo

My simple decision

If it were my store: I'd start with MailerLite if I wanted the lowest-cost, simplest setup, or Omnisend if abandoned carts and purchase-based automations are a major part of the strategy.

If you tell me your ecommerce platform (Shopify/WooCommerce/etc.), approximate number of subscribers, and monthly email volume, I can tell you which one is likely to be cheapest for your specific store and exactly which automations I'd set up first.

If you’re running a small ecommerce store and watching every dollar, I’d narrow it to three choices: MailerLite, Brevo, and Omnisend. I would not start with Klaviyo unless your store is already generating enough revenue to justify it.

My pick: MailerLite

mailerlite.com is probably the best bang-for-your-buck option if you want newsletters and automated sequences without paying much.

• Good drag-and-drop email editor
• Visual automation builder
• Signup forms/landing pages
• Ecommerce integrations
• Relatively inexpensive as your list grows
• Easier to learn than Klaviyo
• Good choice if you're primarily doing email rather than complicated SMS marketing

Current comparisons put MailerLite among the cheapest options for small lists, with paid plans starting around the low-teens per month depending on the plan/list size. SendKite Best Firms

If your list is small: consider Omnisend

omnisend.com is particularly appealing if you're on Shopify or another mainstream ecommerce platform.

Its big advantage is that it's built around ecommerce, rather than adapting a general newsletter tool to ecommerce. You can build things like:

• Welcome sequence
• Abandoned-cart emails
• Post-purchase follow-up
• Product/browse-related sequences
• Win-back campaigns
• Promotional newsletters
• Email + SMS automation

It's more ecommerce-oriented than MailerLite, while generally being cheaper/simpler than going straight to Klaviyo. Shopify's 2026 comparison also specifically includes Omnisend among its ecommerce-focused options. Shopify Axis Intelligence

Cheapest if you have a big list: Brevo

brevo.com uses a send-volume-based model, rather than primarily charging according to how many contacts you have.

That's potentially fantastic if, for example, you have 10,000 subscribers but only send a couple of newsletters per month. You aren't paying simply because those people are sitting in your database. EveryAny.One Telnyx

The downside is that its ecommerce functionality isn't as deep as Omnisend/Klaviyo, and its free tier has a daily sending limit.

What I'd avoid initially: Klaviyo

klaviyo.com is arguably the best ecommerce-specific platform of these, especially when you want sophisticated behavioral segmentation and revenue attribution. But that's also why it can get expensive.

Recent pricing comparisons put it at roughly $20/month around 500 profiles and substantially higher as the list grows. EveryAny.One Drip

I'd move to Klaviyo when you're at the point where better segmentation/automation can realistically make you more money than the extra software costs.

My ranking for you

If it were my money: I'd start with Omnisend if you're on Shopify, otherwise MailerLite. Get your core automated flows working first, rather than paying for an expensive platform with 50 features you won't use.

For a small store, I'd set up these 5 automations before worrying about anything else:

1. Welcome series — 2–4 emails
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank-you → usage/value → review/cross-sell
4. Win-back — customers who haven't purchased in ~60–120 days
5. Newsletter — roughly 1–2 useful/promotional emails per week

If you tell me what platform your store is on (Shopify, WooCommerce, Etsy, etc.), roughly how many subscribers you have, and your monthly email budget ($0 / $10 / $25 / $50), I can tell you exactly which one I'd pick and how I'd set it up.

If you’re a small ecommerce store and budget is the priority, I’d narrow it to Brevo, Omnisend, and Klaviyo rather than the huge email-marketing field.

My pick: Brevo

brevo.com is probably the best value starting point if you want newsletters + automated sequences without committing to a big monthly bill.

• Free: up to 300 emails/day, which can be plenty for a small list.
• Paid: starts around $9/month for higher sending limits.
• Supports automated welcome sequences, abandoned-cart/purchase-related automation, segmentation, forms, and SMS.
• Particularly attractive if you have a relatively large contact list but don't email everyone constantly, because its pricing is more send-oriented than contact-oriented. TechSifted Axis Intelligence

If you're on Shopify: consider Omnisend

omnisend.com is what I'd choose if your priority is ecommerce automation rather than just newsletters.

Its big advantage is that it's built around online stores: abandoned-cart, welcome, browse-abandonment, post-purchase and other ecommerce workflows are ready to go. The free plan is limited, while paid plans start around $16/month. Fit Small Business Toolradar

I'd choose Omnisend over Brevo if: you're on Shopify/WooCommerce and expect email automation to become a meaningful sales channel.

Don't start with Klaviyo unless you need it

klaviyo.com is arguably the best ecommerce email platform, especially for sophisticated segmentation, customer behavior and revenue attribution. But that's precisely why I wouldn't necessarily recommend it on a tight budget. Paid pricing starts around $20/month after the small free tier and rises with your active profiles. Toolradar SMB Compare

I'd move to Klaviyo once your store is generating enough email revenue that the extra sophistication clearly pays for itself.

What I'd actually do

One important point: don't choose based on the newsletter editor. The money is in the automated flows.

For a small ecommerce store, I'd set up these 5 sequences first:

1. Welcome series — 2–3 emails
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank you → usage/value → review → next purchase
4. Win-back — customers who haven't purchased in 60–90 days
5. Newsletter/promotional campaigns — 2–4/month

If you tell me (1) Shopify/WooCommerce/etc., (2) roughly how many email subscribers you have, and (3) your maximum monthly budget, I can tell you exactly which one I'd use and what your setup would cost.

If you’re a small ecommerce store and budget is tight, I’d narrow it to three:

🥇 I'd probably choose Omnisend

For an ecommerce business, it gives you the stuff that actually matters: welcome sequences, abandoned-cart emails, post-purchase flows, segmentation, product-related automation, and newsletters without requiring a huge amount of setup.

Its free plan currently supports up to 250 contacts and 500 emails/month, with automations and segmentation included. Paid plans start around $16/month. Omnisend Omnisend

That's a particularly good fit if you're on Shopify, WooCommerce, BigCommerce, or Wix, since ecommerce integrations are a major focus. Omnisend

💰 If you're really trying to minimize cost: MailerLite

I'd pick MailerLite if your priorities are:

• Send a newsletter every week or two
• Build a welcome sequence
• Have a few basic automations
• Keep the interface simple
• Spend as little as possible

Current pricing is substantially below Klaviyo at comparable list sizes—for example, around $15/month for 1,000 subscribers versus roughly $30 for Klaviyo at that level. Omnisend Omnisend

The tradeoff is that its ecommerce automation and behavioral segmentation aren't as deep.

🚀 Don't start with Klaviyo unless you need it

Klaviyo is excellent, particularly if you're running a Shopify store and eventually want things like:

• Extremely granular customer segments
• Browse/cart/product behavior triggers
• Sophisticated customer journeys
• Revenue attribution
• Predictive analytics
• Lots of personalized ecommerce automation

But you can end up paying for capabilities you won't use when your list and store are small. Klaviyo's free tier is only 250 profiles / 500 sends per month. Omnisend

What I'd do in your position

Start with Omnisend, and build these five automations before worrying about anything fancy:

1. Welcome series — 2–3 emails after someone subscribes
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank-you → product education → review/request
4. Win-back — automatically contact customers who haven't purchased in 60–120 days
5. Newsletter — roughly 1–2 useful/promotional emails per week

That gives you a surprisingly powerful email machine without needing a marketing team.

One important caveat: if your store is on Shopify, Shopify's own email tool is worth considering initially. Shopify currently gives stores 10,000 free email sends/month, making it potentially the absolute cheapest way to get started. Omnisend shopify.com

If you tell me (1) what ecommerce platform you're using, (2) roughly how many subscribers you have, and (3) how many emails you expect to send per month, I can tell you exactly which one I'd choose and what it should cost you.

For a small ecommerce site on a tight budget, I’d usually pick based on one question:

Do you need email mainly as a newsletter tool, or as a sales engine (abandoned carts, welcome flows, repeat purchases, win-backs)?

For ecommerce, automated sequences are where the money is, so I’d lean toward ecommerce-focused tools. Choose My Stack BestSends

My top picks

🥇 Best overall: klaviyo.com

Cons:

• Ecommerce automations and segmentation are not as specialized as Klaviyo

Best for:

• Early-stage stores
• Simple promotions and announcements

Choose My Stack Mailercloud

Good middle ground: mailerlite.com

Best if you want cheap + easy

Pros:

• Clean interface
• Affordable
• Good landing pages and basic automations

Cons:

• Less ecommerce-focused than Klaviyo

Good fit for:

• Handmade shops

SaaSProbe

What I’d do with a tight budget

If you have <1,000 subscribers:

Start with:

1. Klaviyo free tier (if your store is Shopify/WooCommerce)
2. Or Brevo/MailerLite if cost is the priority

Set up only these flows first:

1. Welcome series

• Email 1: brand story + offer
• Email 2: best sellers/social proof
• Email 3: product education
• Abandoned cart

• Reminder after a few hours
• Follow-up after 1–2 days
• Post-purchase

• Thank you
• How to use product
• Review request
• Cross-sell
• Win-back

• “Still interested?” after 60–90 days

Those four automations usually outperform sending lots of random newsletters.

My recommendation by situation

• Shopify store + serious about growing: Klaviyo
• Under $50/month and watching every dollar: Brevo
• Just starting and want simplicity: MailerLite or Mailchimp
• Selling products with repeat purchases (beauty, food, supplements, apparel, etc.): Klaviyo is likely worth paying for sooner

If you tell me:

1. your ecommerce platform (Shopify, WooCommerce, Etsy, custom, etc.),
2. your current subscriber count,
3. monthly revenue or order volume,
4. your budget/month,

I can narrow it down to one choice.

For a small ecommerce site on a tight budget, I’d avoid overbuying. You mainly need:

• newsletters/broadcasts
• welcome series
• abandoned cart emails
• post-purchase follow-ups
• basic segmentation (new customers vs repeat buyers)
• Shopify/WooCommerce integration (if applicable)

My shortlist:

🥇 Best overall budget pick: Brevo

brevo.com

Best if you want to spend the least while still getting automation.

Pros:

• Very affordable entry point
• Pricing is based more on emails sent than just contacts, which can be cheaper if you have a growing list but don’t email constantly
• Includes email automation, forms, and transactional email features
• Good for newsletters + basic customer journeys SendKite SaaSProbe

Cons:

• Ecommerce personalization is not as deep as dedicated ecommerce tools
• Less powerful for complex product-based segmentation

I’d pick this if: you have <10,000 subscribers, are testing email seriously, and want to keep costs under ~$20/month.

🥈 Best ecommerce-focused choice: Klaviyo

klaviyo.com

Best if your store is on Shopify and email revenue matters.

Pros:

• Excellent ecommerce integrations
• Strong abandoned cart, browse abandonment, post-purchase, and win-back flows
• Great customer segmentation based on purchases and behavior Automation Atlas Choose My Stack

Cons:

• Gets expensive as your subscriber list grows
• More setup than simpler tools

I’d pick this if: your store already makes consistent sales and you want email to become a major revenue channel.

🥉 Best simple beginner option: MailerLite

mailerlite.com

Pros:

• Very easy email builder
• Clean interface
• Good for newsletters and simple automations
• Usually less overwhelming than bigger platforms SMTPedia - Everything Email SaaSProbe

Cons:

• Less ecommerce-specific intelligence than Klaviyo

I’d pick this if: your store is small and you mostly want attractive newsletters plus a few automated sequences.

Other options worth considering

• Omnisend — good middle ground for ecommerce brands wanting email + SMS automation. SMTPedia - Everything Email

omnisend.com

• Mailchimp — easy to start, lots of templates, but I’d choose it mainly if you already use it or need general marketing rather than ecommerce-heavy automation. Choose My Stack

mailchimp.com

My recommendation by store size

• Just starting (<1,000 subscribers): MailerLite or Brevo
• 1,000–10,000 subscribers + Shopify: Brevo if budget is tight; Klaviyo if sales justify it
• Already doing meaningful monthly revenue: Klaviyo
• Need email + SMS together: Omnisend

If I were setting up a new small ecommerce store with limited cash, I’d start with Brevo, build these 5 automations, and only move to Klaviyo once email revenue proves it can pay for itself:

1. Welcome email series (3–5 emails)
2. Abandoned cart sequence
3. Post-purchase thank-you + review request
4. Product education sequence
5. Win-back campaign for inactive customers

If you tell me your platform (Shopify, WooCommerce, Etsy, custom site, etc.), monthly orders, and current subscriber count, I can narrow it down to one choice.

For a small ecommerce site on a tight budget, I’d usually avoid jumping straight into the “enterprise” tools. You want something that does the money-making automations:

• Welcome email series
• Abandoned cart recovery
• Post-purchase follow-ups
• Product recommendations
• Customer win-back emails
• Regular newsletters

Here are my top picks:

🥇 Best overall budget choice: Omnisend

Choose My Stack OmnisendBest for: Shopify/WooCommerce stores that want ecommerce automation without a big bill.

Why I’d pick it:

• Built specifically for ecommerce (not just newsletters)
• Strong pre-built flows (welcome, cart abandonment, post-purchase)
• Easier setup than many advanced tools
• Email + SMS options if you grow into them
• Usually cheaper than the more advanced ecommerce platforms at smaller list sizes Chase Dimond

Good starting setup:

1. Free plan while your list is small
2. Create: - Welcome series (3 emails)
3. Abandoned cart (2–3 emails)
4. Post-purchase thank-you/review flow
5. Monthly newsletter

🥈 Best if you want maximum power later: Klaviyo

Choose My StackBest for: Stores already making consistent sales and wanting sophisticated segmentation.

Pros:

• Excellent customer data tracking
• Very strong ecommerce integrations
• Advanced segments (“customers who bought X but not Y,” “VIP buyers,” etc.)
• Great reporting

Cons:

• Costs can climb as your subscriber list grows
• More setup complexity

I’d choose Klaviyo if your store is already generating enough revenue that email is becoming a major sales channel.

🥉 Cheapest/simple option: Brevo

TajoBest for: Very small businesses that care more about low cost than advanced ecommerce features.

Pros:

• Pricing is more send-volume based rather than purely contact-count based
• Good for newsletters and basic automation
• Can be very affordable if you have a large list but don’t email constantly Tajo

Cons:

• Less ecommerce-focused than Omnisend/Klaviyo

I’d probably skip (for your situation)

Mailchimp

Good beginner tool, but it’s more of a general email marketing platform. For a store, ecommerce-first tools often give you better automation value. Choose My Stack

ActiveCampaign

Excellent automation, but probably more complexity than you need unless you have complicated customer journeys. Tajo

My recommendation by store stage

• Under 1,000 subscribers / just starting: Omnisend or Brevo
• 1,000–10,000 subscribers and growing: Omnisend
• Selling seriously and email drives meaningful revenue: Klaviyo
• Mostly newsletters, not much automation: Brevo or Mailchimp

If I were launching a small ecommerce store today with limited cash, I’d start with Omnisend, build the core automated flows, and only move to Klaviyo when the extra segmentation would clearly pay for itself.

If you tell me:

1. what platform you use (Shopify, WooCommerce, Etsy, custom site, etc.),
2. your approximate subscriber count, and
3. whether you sell physical products or digital products,

I can narrow it down to the best fit.

For a small ecommerce site on a tight budget, I’d usually avoid overpaying for a big marketing suite at the beginning. The best choice depends on your store platform (Shopify, WooCommerce, etc.), list size, and whether you care more about simple newsletters or revenue-driving automations like abandoned cart and post-purchase flows. Choose My Stack

My shortlist:

SendKite SMB Compare## My recommendation by situation

If you’re on Shopify and under ~$10k/month revenue

Start with Omnisend.

Set up:

1. Welcome series (3–5 emails)
2. Abandoned cart sequence
3. Post-purchase follow-up
4. Customer win-back campaign
5. Weekly newsletter

It gives you ecommerce-specific automation without paying for a more advanced system too early. SendKite

If you’re very budget constrained (<1,000 subscribers)

Consider:

• MailerLite if you mostly want newsletters and occasional promos
• Omnisend free tier if your priority is ecommerce automations

SendKite Daily Vanguard### If email is already driving meaningful sales

Move toward Klaviyo. It becomes more valuable when you need detailed segments like:

• Customers who bought product A but not product B
• High-value customers
• People who browsed but didn’t purchase
• Customers likely to churn

Choose My Stack SoftwareInspect## The setup I’d use for a lean ecommerce brand

Month 1

• Pick Omnisend (or MailerLite if you only need newsletters)
• Import customers
• Create 5 automated flows
• Send 1 newsletter/week

Month 2–3

• Add segmentation
• Test subject lines
• Add product recommendations
• Measure revenue per email, not just opens

I would not start with an expensive enterprise tool or a complicated CRM unless you already have thousands of customers and lots of repeat purchase data.

If you tell me:

1. your platform (Shopify/WooCommerce/etc.),
2. your subscriber count, and
3. roughly how many orders/month you get,

I can narrow it down to the cheapest option that won’t force you to migrate later.

If you’re a small ecommerce store and budget is the priority, I’d start with MailerLite.

My ranking

1. MailerLite — best overall for your situation

• Free up to 2,500 emails/month
• Free plan includes ecommerce integrations, signup forms/popups, and 3 visual automations
• Paid Comfort starts at $12/month and adds up to 50 automations, 100 automation steps, dynamic content, etc. MailerLite MailerLite
• Good balance of cheap + easy + powerful enough for a small store.
• Brevo — best if you have a relatively large list but don't email constantly

• Free plan: 300 emails/day, with up to 100,000 contacts stored.
• Starter starts at $9/month and removes the daily sending limit, with pricing based largely on email volume. Brevo Help
• Particularly attractive if you have, say, 5,000–20,000 subscribers but only send a few campaigns each month.
• Klaviyo — best ecommerce functionality, but I'd wait

• Excellent ecommerce segmentation, customer behavior tracking, revenue attribution, and automations.
• But its free tier is only 250 profiles / 500 emails per month, so you'll hit the ceiling quickly. Klaviyo
• I'd move to Klaviyo once your store has enough revenue that sophisticated segmentation and lifecycle marketing justify the cost.

What I'd actually set up

For a small store, you don't need 50 complicated automations. I'd build these 5 sequences:

• Welcome: 3–4 emails over ~7 days
• Abandoned cart: 2–3 emails
• Post-purchase: thank you → usage tips → cross-sell/review
• Win-back: target customers who haven't purchased in 60–120 days
• New subscriber → first purchase: educational/value emails followed by an offer

Then send your regular newsletter 1–2 times per week.

My pick: MailerLite initially. It gives you enough automation to build a serious ecommerce email program without immediately turning email software into a significant monthly expense. Its current free tier is unusually generous for a small operation. MailerLite

If you tell me what ecommerce platform you use (Shopify, WooCommerce, Wix, etc.), roughly how many customers/email subscribers you have, and how many emails you expect to send per month, I can tell you exactly which plan I'd choose and whether MailerLite, Brevo, or Klaviyo will be cheapest for you.

If you're running a small ecommerce store and watching every dollar, I’d narrow it to three choices:

🥇 My pick: Brevo

For a genuinely tight budget, Brevo is probably where I'd start. Its pricing is based primarily on emails sent rather than the number of contacts stored, which can be a big advantage as your customer list grows. Current comparisons put its free tier at around 300 emails/day, with paid plans starting around $9/month. EveryAny.One SaaSProbe

You can build things like:

• Welcome sequence
• Abandoned-cart emails
• Post-purchase follow-up
• Product recommendation emails
• Win-back campaigns
• Regular newsletters
• Basic segmentation and automation

The main downside is that Klaviyo has substantially deeper ecommerce-specific customer behavior tracking and segmentation. EveryAny.One SMB Compare

🥈 If you want the easiest experience: MailerLite

mailerlite.com is excellent if you don't need extremely sophisticated ecommerce automation.

It's particularly good for a small operation where you want to get:

signup form → welcome series → weekly newsletter → occasional promotional sequence

working without spending days learning the software.

The catch is that its pricing is contact-based, so it can become less attractive as your list gets large. Recent pricing comparisons show roughly $19/month around 1,000 contacts and substantially more as the list grows. EveryAny.One

🥉 When I'd choose Klaviyo

klaviyo.com is what I'd choose if email is going to be a major revenue channel for your store.

It's particularly strong for ecommerce because it can use things like:

• What someone bought
• What they viewed
• Whether they abandoned a cart
• How much they've spent
• How recently they purchased
• Their purchase frequency
• Specific products/categories they've interacted with

That lets you create much smarter flows. But you're paying for that capability: current comparisons put Klaviyo at about $20/month around 500 profiles, versus cheaper alternatives, with the price increasing considerably as your list grows. EveryAny.One Drip

What I'd actually do

If this were my small ecommerce business with a tight budget, I'd start with Brevo, unless your store is on Shopify and you specifically want sophisticated customer/product-based automation.

I'd build just these 5 automations initially:

1. Welcome series — 3 emails
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank-you → product education → review request
4. Win-back — triggered after ~60–90 days without purchasing
5. Weekly/biweekly newsletter — products, offers, useful content

Don't over-engineer it. Those flows will get you much further than having 30 complicated automations.

One important caveat: if you tell me what ecommerce platform you're using (Shopify, WooCommerce, Squarespace, etc.), roughly how many subscribers you have, and how many emails you expect to send per month, I can tell you which one is likely to be cheapest for your exact situation and what I'd set up first.

🥉 When I'd choose Klaviyo

If you’re running a small ecommerce store and keeping costs tight, I’d shortlist these three:

My recommendation: MailerLite

For a tight budget, I'd start with MailerLite. Its free plan currently supports up to 250 subscribers and 2,500 emails/month, plus campaigns and 3 automations. The paid Comfort plan starts at $12/month and adds substantially more automation functionality. MailerLite MailerLite

For a typical small store, that's enough to build:

• Welcome sequence → 3–5 emails
• Abandoned-cart sequence
• Post-purchase thank-you
• Product education sequence
• Review request
• Win-back campaign
• Weekly/biweekly newsletter
• Basic customer segmentation

When I'd choose Omnisend instead

If your store is on Shopify/WooCommerce/etc. and you want the software to understand ecommerce events—products viewed, carts abandoned, orders placed, repeat purchases, etc.—I'd seriously consider Omnisend.

Its current free tier is 250 contacts/500 emails per month, while Standard starts at $16/month. It's explicitly built around ecommerce and includes ecommerce-oriented automation and segmentation. Omnisend Help Center Omnisend

I'd pay the extra few dollars for Omnisend if automated revenue generation is more important to you than having the absolute cheapest platform.

What about Klaviyo?

klaviyo.com is excellent, particularly once you're doing sophisticated ecommerce segmentation and personalization. But I wouldn't start there on a tight budget unless you already have a fairly substantial store.

Its free tier is currently limited to 250 active profiles and 500 email sends/month. Klaviyo

One interesting alternative: Brevo

brevo.com is worth considering if you have a large subscriber list but don't email very frequently. Its free plan allows up to 100,000 stored contacts but limits you to 300 emails/day; its Starter plan starts at $9/month. Brevo Help

So if you told me:

"I have 800 customers/subscribers, I want a weekly newsletter plus abandoned-cart and welcome sequences, and I don't want to spend more than $20/month."

I'd probably go Omnisend or MailerLite, with MailerLite winning if price is the #1 priority and Omnisend winning if ecommerce automation is the #1 priority.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Squarespace, etc.), roughly how many subscribers you have, and your monthly budget, I can give you a very specific recommendation and the exact setup I'd use.

If you’re running a small ecommerce store and money is tight, I’d narrow it to three:

1. omnisend.com — my pick for most small ecommerce stores

• Built specifically for ecommerce.
• Good abandoned-cart, welcome, post-purchase, win-back, and product-related automations.
• Supports email + SMS/push if you eventually want them.
• Current comparisons put it around $16/month at the entry paid tier, with a limited free plan. SMB Compare Drip
• Best balance of capability and cost.
• brevo.com — best if your list is growing but you don't email constantly

• Pricing is based primarily on emails sent rather than number of contacts, which can be a huge advantage.
• Free tier allows roughly 300 emails/day; paid plans start around $9/month. EveryAny.One Telnyx
• Automation is good, though ecommerce-specific behavioral segmentation isn't as deep as Klaviyo.
• Best budget choice if you have lots of subscribers but send relatively few campaigns.
• klaviyo.com — best, but I'd wait until you have enough sales to justify it

• Excellent Shopify/WooCommerce integration and extremely strong ecommerce automation/segmentation.
• Great for flows like abandoned cart → browse abandonment → purchase → replenishment → VIP → win-back.
• Free tier is currently only around 250 profiles, with paid pricing rising as your audience grows. SMB Compare Klaviyo
• Best if email is becoming a major revenue channel, rather than something you're just getting started with.

What I'd do in your shoes

Under ~1,000 subscribers: start with Omnisend or Brevo rather than paying for Klaviyo.

I'd set up these automations first:

• Welcome series: 3 emails
• Abandoned cart: 2–3 emails
• Post-purchase: thank you → product education → cross-sell
• Win-back: 30–60 days after purchase
• Review request
• Weekly/biweekly newsletter

You don't need 20 complicated automations. Those few flows can cover a surprisingly large chunk of ecommerce email revenue.

If you're on Shopify specifically, I'd lean Omnisend. If you're extremely price-sensitive, I'd lean Brevo. If you're already doing substantial sales and want sophisticated customer segmentation, I'd graduate to Klaviyo.

If you tell me (1) what ecommerce platform you're using, (2) roughly how many customers/subscribers you have, and (3) your monthly email budget, I can tell you exactly which one I'd choose and what plan I'd use.

If you're running a small ecommerce store and watching costs closely, I’d narrow it down to Omnisend, MailerLite, and Brevo rather than jumping straight to Klaviyo.

My pick: Omnisend

omnisend.com is probably the best price-to-ecommerce-automation choice.

It is built specifically around ecommerce, so you can set up things like:

• Welcome series
• Abandoned-cart emails
• Browse abandonment
• Post-purchase follow-ups
• Cross-sells/upsells
• Win-back campaigns
• Regular newsletters
• Email + SMS automations

Its free tier is limited, but the paid plans are relatively inexpensive for a small store. Current comparisons put the entry paid plan around $16/month, with ecommerce-specific automation included. SMTPedia - Everything Email Axis Intelligence

How I'd rank them

MailerLite is the one I'd choose if newsletters are your main priority and your automations are fairly simple. It's inexpensive and easy to use, but its ecommerce functionality isn't as deep as Omnisend or Klaviyo. SendKite Dupple

Brevo becomes particularly attractive if you have a relatively large customer list but don't email everyone constantly, because its pricing is based largely on emails sent rather than number of contacts. SMTPedia - Everything Email Axis Intelligence

Klaviyo is excellent, but I wouldn't pay for it prematurely. Its big advantage is sophisticated segmentation, behavioral data, and revenue-focused ecommerce automation. For a tiny store, you're likely paying for capabilities you won't use yet. SMTPedia - Everything Email SMB Compare

And if you're on Shopify, Shopify Messaging/Email is worth considering initially: Shopify currently includes 10,000 free emails per month, making it extremely hard to beat on pure cost when you're starting out. Shopify

What I'd actually do

If your budget is really tight:

Shopify → Shopify Email initially → Omnisend once you need more automation.

If you can spend around $15–20/month now:

Go straight to Omnisend.

I'd then build these 5 automations before worrying about fancy newsletters:

1. Welcome: 2–3 emails over ~5 days
2. Abandoned cart: 2–3 emails
3. Post-purchase: thank-you → usage/value → cross-sell
4. Win-back: customers who haven't bought in 60–120 days
5. Newsletter: 1–2 genuinely useful/promotional emails per week

That's enough to create a surprisingly effective automated email machine without turning your marketing stack into a $200/month project.

If you tell me (1) what ecommerce platform you're using (Shopify/WooCommerce/etc.), (2) roughly how many email subscribers you have, and (3) your maximum monthly budget, I can tell you exactly which one I'd pick and what your initial automation setup should look like.

If you’re a small ecommerce store on a tight budget, I’d narrow it down to three:

1. omnisend.com — my pick for most ecommerce stores

• Built specifically for ecommerce.
• Strong prebuilt automations for welcome series, abandoned cart, browse abandonment, post-purchase, and win-back.
• Free tier, with paid plans starting around $16/month according to current 2026 comparisons. Fit Small Business Omnisend
• Particularly good if you're on Shopify, WooCommerce, or BigCommerce.
• Best balance of price + automation + ecommerce features.
• brevo.com — cheapest if you have a growing list

• Its big advantage is that it primarily charges based on emails sent rather than number of contacts.
• Free plan allows unlimited contacts with sending limits; paid plans start around $9/month. Tajo Omnisend
• Great if you have, say, 5,000 subscribers but only email them a few times a month.
• Automation is good, although the ecommerce-specific experience isn't as deep as Omnisend or Klaviyo.
• klaviyo.com — best, but I'd probably wait

• Excellent ecommerce/customer-data integration and very sophisticated segmentation and flows.
• Free tier is available, but costs rise with your contact base. Shopify Omnisend
• I'd choose it if you're already doing significant sales and expect email to become a major revenue channel.
• For a tiny store watching every dollar, it's probably more platform than you need right now.

What I'd actually do

If you're starting from scratch, I'd use Omnisend and set up these five automations first:

• Welcome series: 2–3 emails after signup
• Abandoned cart: 2–3 emails
• Post-purchase: thank-you → product education → review/cross-sell
• Win-back: after ~60–90 days without purchasing
• Browse abandonment: if your store has enough traffic to make it worthwhile

Then send 1–2 newsletters/promotional campaigns per week.

That gives you a surprisingly sophisticated email program without needing to pay for a giant marketing platform.

One important exception: if you're using Shopify and your budget is extremely tight, Shopify's own email tool is worth considering first. Shopify currently includes 10,000 free emails/month, after which additional emails are charged per 1,000. Shopify

If you tell me (1) Shopify/WooCommerce/etc., (2) roughly how many email subscribers you have, (3) monthly revenue, and (4) whether you want SMS too, I can tell you which one I'd choose and what it should cost you.

If you’re a small ecommerce store and money is tight, I’d narrow it to three choices rather than paying for a heavyweight platform immediately.

My picks

Current 2026 comparisons consistently put MailerLite and Brevo among the strongest budget choices, while Klaviyo remains the more ecommerce-specialized option. Shopify smbcompare.com Telnyx

What I'd do in your shoes

Start with MailerLite if you're early-stage.

You can build the important stuff:

• Welcome sequence when someone joins your list
• Abandoned-cart emails
• Post-purchase follow-up
• Product/customer segments
• Regular newsletters
• Win-back emails for customers who haven't purchased recently

Its big advantage is that you aren't paying for a giant marketing platform before you actually need one. Current pricing comparisons put the entry level around $10/month, with a free tier available at smaller list sizes. Shopify TechRadar

Choose Brevo instead if you expect your subscriber list to get large but don't plan to email everyone constantly. Its send-based pricing can make much more sense than contact-based pricing in that situation. SendKite StacksVerdict

Choose Klaviyo from the beginning if your store is already doing meaningful sales and you specifically want sophisticated ecommerce automation—e.g. "bought product A → wait 14 days → recommend B," VIP segments, browse/cart behavior, revenue attribution, etc. That's where its additional cost starts making sense. smbcompare.com Axis Intelligence

One important exception

If you're on Shopify, I'd also look seriously at Shopify Messaging/Email before buying anything else. Shopify currently gives stores a free monthly allocation of email sends, and it lives directly inside your Shopify admin. Shopify

So my budget ladder would be:

$0 → Shopify Email
~$10/mo → MailerLite
~$9/mo → Brevo if you have a large/low-frequency list
$20+/mo → Klaviyo when ecommerce automation becomes important

If you tell me (1) Shopify/WooCommerce/other, (2) roughly how many subscribers you have, and (3) how many emails you expect to send per month, I can tell you which one I'd pick and what it should cost you.

If you’re running a small ecommerce store and watching every dollar, I’d narrow it down to MailerLite, Brevo, and Klaviyo.

My pick: MailerLite

mailerlite.com is probably the best balance of cheap + easy + enough automation for your situation.

It supports newsletters, visual automations, ecommerce triggers, abandoned-cart flows, purchase-based automations, segmentation, landing pages, and integrations with ecommerce platforms. MailerLite MailerLite

When I'd choose each

1. MailerLite — start here

Great if you have a few hundred to a few thousand subscribers and want to build:

• Welcome sequence
• Abandoned-cart emails
• Post-purchase sequence
• Product education sequence
• Review request
• Win-back campaign
• Weekly/monthly newsletters

Its ecommerce offering specifically includes triggers such as abandoned cart, product purchases, and subscriber behavior. MailerLite MailerLite

2. Brevo — choose this if your list gets big

brevo.com has an unusual pricing model: you're primarily paying based on emails sent rather than number of contacts. That can be extremely attractive if you have, say, 10,000–50,000 subscribers but only email them occasionally. SMB Compare GetOmnichannel

The downside is that its ecommerce automation isn't as deep as Klaviyo's.

3. Klaviyo — upgrade when email becomes a major revenue channel

klaviyo.com is the one I'd eventually consider if you're on Shopify/WooCommerce and email is becoming a meaningful part of your revenue.

It's particularly strong at using purchase history, browsing behavior, cart activity, customer segments, and revenue attribution to make sophisticated automations. Shopify Drip

But I wouldn't pay for that complexity prematurely.

What I'd actually build

Don't overcomplicate it. I'd start with 5 automated sequences:

1. Welcome: 3–4 emails introducing your brand/product and making the first purchase offer.
2. Abandoned cart: 2–3 emails reminding people about what they left behind.
3. Post-purchase: thank you → product tips → review request → related product.
4. Repeat purchase: reminder timed around when the customer is likely to need/order again.
5. Win-back: email customers who haven't purchased in ~60–120 days.

Then send 1 useful promotional/newsletter email per week.

That's enough automation to make email a serious sales channel without turning your marketing stack into a full-time job. Ecommerce automation is particularly valuable because purchase-triggered flows can outperform ordinary broadcasts. MailerLite

Bottom line: I'd start with MailerLite, keep your monthly software cost as close to $0 as possible, and move to Klaviyo only once your store has enough customers/data that its deeper ecommerce segmentation can actually pay for itself.

If you tell me what platform your store is on (Shopify, WooCommerce, etc.), your approximate number of customers/email subscribers, and your monthly email budget, I can tell you exactly which one I'd use and what the cheapest setup would be.

If you’re a small ecommerce store on a tight budget, I’d narrow it to three:

My pick: Omnisend

For an ecommerce business specifically, I'd start with Omnisend. It is designed around ecommerce rather than being a generic newsletter platform, with visual workflows and ecommerce triggers. Its free tier currently includes the core features and up to 500 emails/month; paid plans start around $16/month. www.omnisend.com

The important part is that you can set up things like:

• Welcome sequence — 2–3 emails after someone subscribes
• Abandoned cart
• Post-purchase thank you
• Product review request
• Cross-sell/upsell
• Win-back — "We miss you" after 60–90 days
• Regular newsletters/promotions

That's much more valuable for an ecommerce store than simply having a nice newsletter editor.

When I'd choose MailerLite instead

If you're really trying to spend as little as possible, MailerLite is compelling. It's cheaper as your list grows and is particularly good if your main requirement is newsletters plus relatively simple automated sequences. Current comparisons put it around $15/month at 1,000 contacts, versus roughly $20 for Omnisend. www.omnisend.com

The tradeoff is that Omnisend has more ecommerce-specific functionality.

Don't start with Klaviyo unless you need it

Klaviyo is excellent, but I'd resist the temptation to use it just because it's popular with ecommerce brands.

Its free tier is only 250 contacts, and paid pricing rises considerably as your list grows—for example, around $100/month at 5,000 contacts and $150/month at 10,000 under current pricing. www.omnisend.com

It's worth moving there when you have enough customers/data that sophisticated segmentation and analytics can materially increase revenue.

One exception: if you're on Shopify

If your store is Shopify and money is extremely tight, I'd actually consider starting with Shopify Messaging/Email. Shopify currently gives stores up to 10,000 free emails/month, making it hard to beat on cost. www.omnisend.com

My progression would be:

$0 → Shopify Email
↓
$16-ish/mo → Omnisend once you need better automation
↓
Klaviyo once your customer base/revenue justifies sophisticated segmentation

If you tell me (1) Shopify/WooCommerce/other, (2) roughly how many customers/emails you have, and (3) your monthly budget ($0, $10, $20, $50, etc.), I can tell you exactly which one I'd use and what automations I'd set up first.

If you’re running a small ecommerce store and money is tight, I’d narrow it down to three:

My recommendation: Omnisend

For an ecommerce store, I'd probably start with Omnisend. It's specifically designed around ecommerce rather than being a generic newsletter tool, and it supports automated workflows such as welcome series, abandoned-cart recovery, post-purchase messages, segmentation, and email/SMS flows. Current pricing starts around $16/month for 500 contacts, with a free plan available. www.omnisend.com

The big advantage is that you can set up the important automations once and let them run:

New subscriber → Welcome sequence → First purchase

Adds to cart → Doesn't buy → Abandoned-cart sequence

Purchases → Thank-you → Product education → Review request → Repeat-purchase offer

Then use regular newsletters for promotions, new products, educational content, etc.

If your budget is really tight: Brevo

I'd choose Brevo if your main concern is minimizing the monthly bill. Its pricing is based much more on emails sent rather than simply the number of contacts, which can be advantageous if you have a growing list but don't email everyone constantly. Current plans start around $9/month, and there's a free tier. www.omnisend.comwww.drip.com

The tradeoff is that its ecommerce-specific automation isn't as deep as Omnisend or Klaviyo.

I wouldn't start with Klaviyo—yet

Klaviyo is excellent and arguably the strongest option once you're doing serious ecommerce lifecycle marketing. It has excellent customer segmentation, purchase-based targeting, revenue attribution, and Shopify/WooCommerce integrations. But its pricing grows with your customer database, so I'd avoid paying the premium while you're still small unless you already know you'll use its advanced capabilities. smbcompare.comwww.drip.com

One exception: if you're on Shopify

If you're using Shopify, also look at Shopify Email before paying for anything. It's extremely inexpensive for basic campaigns, with 10,000 free emails/month according to current 2026 comparisons. www.omnisend.comwww.drip.com

It's a good way to start, but I'd move to Omnisend once automated customer journeys become important.

My ranking for you:

1. 🥇 Omnisend — best balance of price + ecommerce automation
2. 🥈 Brevo — cheapest if controlling costs is priority #1
3. 🥉 Klaviyo — best long-term sophistication, but probably unnecessary initially
4. Shopify Email — excellent if you're on Shopify and want to spend almost nothing

If you tell me what platform your store runs on (Shopify, WooCommerce, Wix, etc.), roughly how many subscribers you have, and your monthly email budget ($0 / $10 / $20 / $50), I can tell you exactly which one I'd pick and what automations I'd set up first.

If you’re a small ecommerce store and budget is the priority, I’d narrow it to three:

🥇 My pick: Omnisend

omnisend.com is probably the best overall fit.

Why:

• Built specifically for ecommerce rather than generic newsletters.
• Excellent pre-built automations for welcome series, abandoned cart, post-purchase, win-back, etc.
• Integrates with Shopify and other major ecommerce platforms.
• You can start free, and paid plans currently start around $16/month. Omnisend Omnisend
• You can add SMS later without having to migrate platforms.

For a small store, I particularly like that you don't have to spend weeks building complicated automations yourself.

🥈 Cheapest if you send lots of emails: Brevo

brevo.com is worth considering if your list is relatively large but you don't send extremely frequently.

Its big advantage is send-based pricing rather than primarily contact-based pricing, so having 5,000–10,000 subscribers doesn't necessarily mean your bill explodes. Current comparisons put paid plans around $9–$17/month depending on usage. Brevo Omnisend

The downside: its ecommerce automation isn't as polished/deep as Omnisend or Klaviyo.

🥉 Klaviyo — best, but probably unnecessary initially

klaviyo.com is what I'd choose once email becomes a major revenue channel for your store.

It's extremely good at behavioral segmentation—e.g. customers who bought X but haven't bought Y within 60 days—and has excellent ecommerce data integration. But you're paying for capabilities you may not need when you're small. Paid pricing starts around $20/month depending on list size. SMTPedia - Everything Email Omnisend

What I'd actually do

If this were my store:

There is also Shopify Messaging if you're on Shopify: Shopify currently offers up to 10,000 free marketing emails/month, making it potentially the absolute cheapest option while you're small. Omnisend Shopify

My recommendation: start with Omnisend. Don't over-optimize the software yet. The important thing is getting these 5 automations running:

1. Welcome series
2. Abandoned cart
3. Browse abandonment
4. Post-purchase / cross-sell
5. Win-back for customers who haven't purchased recently

Those will generally matter far more to your revenue than whether you picked Omnisend vs. Klaviyo.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, etc.), roughly how many subscribers you have, and your monthly order volume, I can tell you which one is likely to be cheapest for your specific store and what I'd set up first.

🥉 Klaviyo — best, but probably unnecessary initially

klaviyo.com is what I'd choose once email becomes a major revenue channel for your store.

It's extremely good at behavioral segmentation—e.g. customers who bought X but haven't bought Y within 60 days—and has excellent ecommerce data integration. But you're paying for capabilities you may not need when you're small. Paid pricing starts around $20/month depending on list size. smtpedia.com Omnisend

What I'd actually do

If this were my store:

There is also Shopify Messaging if you're on Shopify: Shopify currently offers up to 10,000 free marketing emails/month, making it potentially the absolute cheapest option while you're small.

For a small ecommerce site on a tight budget, I’d usually avoid paying for a “marketing suite” and focus on a tool that can do the automations that actually make money:

• welcome series
• abandoned cart emails
• post-purchase follow-ups
• win-back campaigns
• product recommendations
• basic segmentation

My shortlist:

www.drip.com

My recommendation by situation

If you’re under ~1,000 subscribers and just starting:
→ Omnisend or Shopify Email

You can set up:

• welcome discount email
• abandoned cart
• order follow-up
• “come back and shop” emails

without a big monthly bill. Omnisend is more ecommerce-focused; Shopify Email is extremely cheap if you already use Shopify. www.drip.com

If you have a Shopify store and expect to grow:
→ Start with Omnisend, move to Klaviyo later if needed

Klaviyo is excellent because it uses customer behavior data (what they viewed, bought, abandoned, etc.) for advanced segmentation and revenue tracking, but you’re paying for that power. www.digitalestatemedia.com

If money is the absolute priority:
→ Brevo

Brevo’s pricing model can be attractive because it focuses more on email volume rather than simply charging for every stored contact, which can work well for smaller businesses with larger but less-active lists. www.drip.com

The automations I’d build first (highest ROI)

1. Welcome sequence
   • Email 1: brand story + discount/offer
   • Email 2: best sellers
   • Email 3: reviews/social proof

2. Abandoned cart
   • 1 hour: reminder
   • 24 hours: benefit + objection handling
   • 72 hours: final nudge

3. Post-purchase
   • thank you
   • how to use product
   • review request
   • cross-sell

4. Win-back
   • “still interested?”
   • new products
   • special offer

If you tell me:

1. what platform you use (Shopify, WooCommerce, Etsy, custom site, etc.)
2. your monthly order volume
3. your current email list size

…I can narrow it down to the cheapest option that won’t force you to migrate later.

For a small ecommerce store on a tight budget, I’d narrow it to Omnisend, Brevo, and MailerLite—and my default pick would be Omnisend.

Current 2026 comparisons consistently put Omnisend among the strongest budget ecommerce choices, while Brevo is particularly attractive when you have lots of subscribers but don't email them constantly. fitsmallbusiness.comaxis-intelligence.com

🥇 I'd start with Omnisend

The important distinction is that you don't just want a newsletter tool. You want an ecommerce lifecycle tool.

I'd want it to handle:

• Welcome sequence
• Abandoned-cart emails
• Browse/product-view follow-up
• Post-purchase sequence
• Review request
• Cross-sell/upsell
• Win-back sequence
• Regular promotional newsletters
• Customer segmentation

Omnisend is specifically built around those ecommerce workflows and has native integrations with major ecommerce platforms. Its current paid plans start around $16/month, with a free tier available. www.omnisend.com

Omnisend

💰 When I'd choose Brevo instead

Brevo gets particularly interesting if your mailing list is relatively large but you don't send tons of emails.

That's because Brevo primarily prices around email volume rather than subscriber count. Its current Starter pricing begins around $9/month for 5,000 monthly emails, while the free tier allows 300 emails/day. www.itechguides.com

Brevo

For example, if you had 8,000 subscribers but only sent one newsletter per week, I'd seriously consider Brevo.

🟢 MailerLite if you're extremely cost-sensitive

If your automated sequences are relatively basic and you mainly want attractive newsletters, MailerLite is worth considering. It's simpler than the ecommerce-specialists and tends to be inexpensive, but you give up some of the sophisticated ecommerce triggers/segmentation that make Omnisend or Klaviyo valuable. www.itechguides.com

MailerLite

What about Klaviyo?

Klaviyo is excellent, but I wouldn't automatically put a tiny store on it just because it's the famous ecommerce choice.

It's particularly good when you have enough traffic/orders that deep behavioral segmentation, revenue attribution, and sophisticated customer data justify the additional cost and complexity. Current comparisons put its paid pricing around $20/month at the low end. fitsmallbusiness.comwww.omnisend.comaxis-intelligence.com

Klaviyo

My recommendation: Start with Omnisend, build the core 5–7 automations, and don't spend money on complicated email software until your list/revenue actually demands it.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, etc.), roughly how many subscribers you have, and your monthly email budget, I can tell you which one I'd pick and what the cheapest setup would cost.

If you're running a small ecommerce store and watching every dollar, I’d narrow it to three:

Current 2026 comparisons put Omnisend among the strongest ecommerce-specific options, while Brevo is particularly attractive because it prices primarily around emails sent rather than contacts stored. www.omnisend.comtajo.io

What I'd choose

If you're on Shopify or WooCommerce: start with Omnisend.

It's purpose-built for ecommerce, so you get the important automations without having to build everything yourself:

• Welcome series
• Abandoned-cart emails
• Browse abandonment
• Post-purchase follow-up
• Cross-sells/upsells
• Customer segmentation
• Promotional newsletters
• Email + SMS if you eventually want it

It's currently listed at about $16/month for 500 contacts, with a free tier, and has native integrations with Shopify, WooCommerce, BigCommerce and Wix. www.omnisend.com

If you have a large list but don't email them constantly, I'd seriously consider Brevo. Its send-based pricing can be dramatically cheaper than platforms that charge according to the number of contacts you have. tajo.io

I wouldn't start with Klaviyo unless you already have enough sales/data to justify it. It's excellent and probably the platform I'd move to if the store becomes sophisticated, but for a tiny store on a tight budget you're paying for capabilities you may not need yet. Current comparisons put its paid entry around $20/month, versus Omnisend around $16 and Brevo around $9. www.omnisend.com

The setup I'd use on a shoestring

Don't try to build 20 automations. Start with 5:

1. Welcome sequence — 2–3 emails
2. Abandoned cart — 2 emails
3. Post-purchase — thank you → usage tips → cross-sell
4. Win-back — after ~60–90 days without purchasing
5. Weekly/biweekly newsletter — products, offers, useful content

Those automated lifecycle emails are disproportionately valuable: one 2026 ecommerce analysis found lifecycle messages represented a much larger share of email-generated sales than their share of total emails sent. www.omnisend.com

My verdict:
Omnisend if ecommerce automation is the priority. Brevo if absolute cost is the priority. MailerLite if you want the simplest interface.

If you tell me (1) Shopify/WooCommerce/other, (2) roughly how many customers/emails you have, and (3) your maximum monthly budget, I can tell you exactly which one I'd pick and what plan to start with.

If you’re a small ecommerce store and budget is the priority, I’d narrow it to Omnisend, Brevo, and Klaviyo rather than Mailchimp.

My pick: Omnisend

Omnisend is probably the best balance of low cost + ecommerce automation.

It’s built specifically for ecommerce, so you get things like:

• Welcome sequences
• Abandoned-cart emails
• Browse-abandonment flows
• Post-purchase emails
• Win-back campaigns
• Product recommendations
• Segmentation based on purchases
• Email + SMS in the same platform

Its free plan currently allows 250 contacts and 500 emails/month, while paid plans start around $16/month. www.omnisend.com

How I'd compare the options

Brevo is particularly interesting if your mailing list gets large. Brevo charges primarily based on email volume rather than number of contacts, so you can have a large database without paying simply for storing subscribers. Its paid plans start around $9/month. www.stackfyi.com

Klaviyo is what I'd choose if you're expecting to become a serious ecommerce operation and want sophisticated customer segmentation, revenue attribution, predictive analytics, and highly customized flows. But you're likely paying more than you need to at the beginning. www.stackfyi.com

Klaviyo

What I'd actually do in your shoes

If you're under ~1,000 subscribers and watching every dollar:

Start with Omnisend.

Set up these 5 automations immediately:

1. Welcome series — 2–3 emails
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank-you → usage/value → review/UGC
4. Win-back — target customers who haven't purchased in ~60–120 days
5. New-product/promotional newsletter — 1–4× per month

That will give you substantially more value than simply sending occasional newsletters.

One important caveat: your ecommerce platform matters. If you're on Shopify, WooCommerce, Wix, etc., I'd choose somewhat differently because the quality of the integration and available customer/order data is critical.

Tell me what platform your store is on (Shopify, WooCommerce, Wix, Squarespace, etc.) and roughly how many customers/email subscribers you have, and I can tell you exactly which one I'd use and what it should cost you.

For a small ecommerce site on a tight budget, I’d usually start with Omnisend or Klaviyo, depending on how serious you are about scaling. Ecommerce-focused tools generally beat generic newsletter platforms because they connect to customer behavior (orders, abandoned carts, browsing, purchase history). www.mailercloud.com

My ranking:

www.chasedimond.comwww.drip.com

My recommendation by situation

If you have <5,000 subscribers and are trying to grow:
→ Omnisend

• Good abandoned cart flows
• Welcome sequences
• Post-purchase emails
• Product recommendation emails
• Built for Shopify/WooCommerce-style stores
• Lower cost as you grow compared with Klaviyo in many cases www.omnisend.com

If you’re already doing meaningful sales (for example, $10k+/month) and email is becoming a major revenue channel:
→ Klaviyo

• Better segmentation
• More advanced customer data
• Stronger analytics
• More room for complex flows www.mailercloud.com

If you’re extremely cash constrained:
→ Start with MailerLite or your ecommerce platform’s built-in email tool, then migrate later. www.chasedimond.comwww.drip.com

The automations I would set up first

Regardless of platform:

1. Welcome series
   • Email 1: brand/story + offer
   • Email 2: best sellers/social proof
   • Email 3: FAQ + urgency

2. Abandoned cart
   • 1 hour after cart abandonment
   • 24 hours later
   • 72 hours later

3. Post-purchase
   • Order confirmation
   • How to use product
   • Review request
   • Cross-sell

4. Win-back
   • “We miss you”
   • New products
   • Special offer

If you tell me:

• what platform you use (Shopify, WooCommerce, Etsy, custom site, etc.)
• monthly orders/revenue
• current email list size
• whether you want SMS too

…I can narrow it down to the cheapest option that won’t force you to migrate later.

For a small ecommerce store on a tight budget, I’d narrow it to Omnisend, Brevo, and MailerLite rather than jumping straight to Klaviyo.

My pick: Omnisend

If your store is on Shopify, WooCommerce, BigCommerce, or Wix, I’d start with Omnisend.

Why:

• Built specifically for ecommerce rather than general newsletters.
• Strong prebuilt automations for welcome, abandoned cart, post-purchase, browse abandonment, and win-back.
• Email, SMS, and push can be combined into workflows.
• There's a free tier, with paid plans starting around $16/month depending on contacts. www.omnisend.com
• It's considerably cheaper than paying for Klaviyo's deeper analytics before you actually need them.

Best options by situation

Brevo is particularly interesting if your list gets large. It prices primarily by email volume rather than number of contacts, so a 10,000-person list that you email occasionally can be much cheaper than a contact-based platform. Its free tier currently allows 300 emails/day. tajo.iosmtpedia.com

MailerLite is the simpler choice if your automation needs are mostly things like:

Signup → welcome email → 2 days → product education → 3 days → offer → newsletter

It's inexpensive and easy to use, but its ecommerce-specific automation isn't as deep as Omnisend's. www.omnisend.com

Klaviyo is excellent, but I'd consider it a later upgrade. Its big advantage is extremely detailed customer/event data and segmentation. That's valuable once you have enough customers and revenue to justify it; for a tiny store, you can end up paying for sophistication you aren't yet using. smtpedia.com

What I'd actually do

If you're starting from scratch, I'd build these 5 automations first:

1. Welcome series — 3 emails
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank you → usage tips → review/UGC
4. Win-back — target customers who haven't purchased in ~60–90 days
5. Browse abandonment — if your platform supports it

Then send 1–2 newsletters per week.

You don't need a complicated 30-automation setup. Those five flows can cover a surprisingly large portion of ecommerce email revenue.

Bottom line:
👉 Shopify/WooCommerce + want ecommerce automation: Omnisend
👉 Huge list + low sending frequency: Brevo
👉 Mostly newsletters + simple sequences: MailerLite
👉 Growing brand with sophisticated customer data: Klaviyo
👉 Absolute minimum budget on Shopify: Shopify Email

If you tell me what ecommerce platform you're using (Shopify/WooCommerce/etc.), roughly how many subscribers you have, and how many emails you expect to send per month, I can tell you which one is likely to be the cheapest for your specific store.

For a small ecommerce store on a tight budget, I’d narrow it to three:

🥇 My pick: MailerLite

MailerLite gives you 2,500 emails/month for free, plus visual automations, forms/pop-ups, landing pages and A/B testing. Its free tier allows 3 active automations, which is plenty to get an ecommerce operation started. Paid plans currently start around $12/month. www.mailerlite.com

For example, I'd set up:

1. Welcome sequence — 3–4 emails after someone joins
2. Abandoned-cart sequence — 2–3 emails
3. Post-purchase sequence — thank you → usage tips → review request → cross-sell
4. Weekly/biweekly newsletter — products, offers, useful content
5. Win-back sequence — automatically contact customers who haven't purchased in ~60–90 days

That's a surprisingly capable setup for $0.

🥈 Brevo

Brevo is particularly attractive if your subscriber list gets large but you don't email everyone constantly. Its free plan allows 300 email sends per day, and its paid plans start around $9/month. Its Standard plan adds unlimited multi-step automation. help.brevo.com

One advantage is that you're not as tightly constrained by the number of contacts as you are with some competing platforms.

🥉 Klaviyo

Klaviyo is what I'd choose if ecommerce revenue/automation is the priority and you're willing to spend more later. It has excellent ecommerce integrations, segmentation, revenue attribution and sophisticated flows. But its free tier is only 250 active profiles and 500 emails/month, so you'll hit the ceiling fairly quickly. www.klaviyo.com

My rule of thumb:

• Under ~500 subscribers + very tight budget → MailerLite
• Large list + relatively low sending frequency → Brevo
• You want sophisticated customer/product behavior automation → Klaviyo
• Shopify store and you want the absolute simplest/cheapest setup → I'd also consider Shopify's native email tools

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Wix, etc.), roughly how many subscribers you have, and how many emails you expect to send per month, I can tell you which one I'd actually choose and what it will cost you.

If you’re running a small ecommerce store and watching every dollar, I would not start with Klaviyo. It’s excellent, but you can get most of what you need for substantially less.

My picks

Current 2026 comparisons put Omnisend around $16/month at the low end, Brevo around $9/month, and MailerLite around $10/month, although exact pricing depends on contacts/sends and changes over time. smtpedia.com

🥇 I'd choose Omnisend

For an ecommerce business, Omnisend is probably the sweet spot.

You get ecommerce-specific automations such as:

• Welcome series
• Abandoned cart
• Browse abandonment
• Post-purchase follow-up
• Cross-sells/upsells
• Win-back campaigns
• Segmentation based on purchases
• Email + SMS in the same automation system

It's specifically designed around ecommerce rather than treating your store as an afterthought. Recent 2026 comparisons consistently put it among the strongest budget alternatives to Klaviyo. www.omnisend.com

🥈 Choose Brevo if "cheap" is the #1 priority

Brevo is particularly interesting if you have a lot of subscribers but don't email them constantly.

Its big advantage is that it primarily prices around email volume rather than the number of contacts. That means you can have a relatively large database without paying for every inactive subscriber. Its free tier also allows 300 emails/day. tajo.iosmtpedia.com

The tradeoff: its ecommerce automation isn't as polished/deep as Omnisend or Klaviyo.

🥉 MailerLite if you want simplicity

I'd choose MailerLite if your email strategy is basically:

newsletter + welcome sequence + occasional promotions + a few simple automations

It's inexpensive and easy to operate, but it's less ecommerce-native than Omnisend. smtpedia.com

What I wouldn't do

I wouldn't pay for Klaviyo immediately unless your store is already generating enough sales that sophisticated segmentation and revenue attribution justify the cost.

Klaviyo is the better long-term platform if you're going to get serious about lifecycle marketing, but its pricing scales with your contact count and can become considerably more expensive. tajo.iosmtpedia.com

The setup I'd use for a small store

If you told me "I have $20/month and want email to start making sales", I'd put the money into Omnisend and build these five automations first:

1. Welcome: 3 emails over ~5 days
2. Abandoned cart: 2–3 emails
3. Post-purchase: thank you → product education → cross-sell
4. Win-back: target customers who haven't purchased in 60–120 days
5. Browse abandonment: remind people about products they viewed

Then send 1–2 newsletters/promotional campaigns per week.

You don't need 30 complicated automations. Those five will cover the majority of the useful lifecycle marketing for a small store.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Squarespace, etc.), roughly how many customers/subscribers you have, and your monthly email budget ($0, $10, $20, $50...), I can tell you exactly which one I'd pick and what it should cost you.

For a small ecommerce store on a tight budget, I’d shortlist these three:

🥇 I'd probably pick Omnisend

It's specifically built around ecommerce rather than being a generic newsletter platform. Its automation includes things like welcome sequences, abandoned carts, post-purchase flows, and re-engagement, and even the free tier includes automation. www.omnisend.comsupport.omnisend.com

The current free plan is 500 emails/month to up to 250 contacts. The Standard plan starts at $16/month normally, with current introductory pricing shown as $11.20/month for the first three months. www.omnisend.comsupport.omnisend.com

That makes it particularly attractive if you're on Shopify/WooCommerce and want something you can set up once and largely leave running.

🥈 Brevo if you're really watching costs

Brevo has a very generous free tier: 300 emails/day, up to 100,000 stored contacts, and marketing automation for up to 2,000 contacts. Paid plans start at $9/month. help.brevo.com

The catch is that it's more of a general CRM/multichannel marketing platform. For a product-heavy ecommerce operation, I'd take Omnisend's ecommerce-specific workflows over Brevo.

🥉 MailerLite if you want dead-simple

MailerLite is excellent if your primary need is "send a nice newsletter every week + have a few automated sequences." Its automation supports multiple triggers, segmentation, unlimited sends on paid plans, and starts at $12/month. www.mailerlite.com

It's less ecommerce-specialized than Omnisend, though.

What I'd actually set up

Don't overcomplicate this. For a small store, I'd start with 5 automations:

1. Welcome series — 2–3 emails after signup
2. Abandoned cart — 2–3 emails
3. Post-purchase — thank-you → usage tips → review request
4. Win-back — after ~60–90 days without purchasing
5. Product/browse follow-up — if your platform supports it

Then send 1–2 regular newsletters per week.

I would not start with Klaviyo unless you already have enough revenue that its deeper segmentation/analytics justify the additional cost. It's excellent, but for a tiny store on a tight budget, I'd rather put that money into acquiring customers.

My ranking for your situation: Omnisend → Brevo → MailerLite.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Squarespace, etc.), roughly how many subscribers you have, and your monthly order volume, I can tell you which one I'd choose and what it should cost you.

For a small ecommerce store on a tight budget, I’d narrow it to three:

🥇 I'd start with MailerLite

It's inexpensive, relatively easy to set up, and gives you the important stuff: newsletters, signup forms, segmentation, and visual automated sequences. Current comparisons put its paid entry tier around $10–$12/month, with a free tier available depending on the current limits. www.hostinger.com

For a small store, I'd build these automations first:

1. Welcome sequence — 3 emails over ~5–7 days
2. Abandoned cart — reminder + incentive if appropriate
3. Post-purchase — thank-you → product-use tips → review request
4. Win-back — reach out to customers who haven't purchased in ~60–90 days
5. Regular newsletter — perhaps 1–2x/week

You don't need a sophisticated marketing stack initially.

When I'd choose Brevo instead

Brevo becomes particularly attractive if you expect your subscriber list to grow substantially but aren't going to email everyone constantly. Its pricing is based primarily on email volume rather than number of stored contacts, and its free tier allows 300 emails/day. www.hostinger.comtajo.iowww.drip.comsaasprobe.com

So, for example, a store with 10,000 subscribers that sends one newsletter a month can potentially have a much better economics with Brevo than a platform charging primarily by contacts.

When I'd bite the bullet and use Klaviyo

If you're on Shopify/WooCommerce and expect email to become a major sales channel, Klaviyo is worth considering. It has much deeper ecommerce data and can trigger flows from things like purchases, browsing behavior, abandoned carts, and product activity. www.hostinger.comtajo.iowww.drip.comsaasprobe.com

The downside is cost: it starts around $20/month for 500 active profiles and rises with your active-profile count. www.hostinger.comtajo.iowww.drip.comsaasprobe.com

My rule of thumb:

• <$15/month + simple store → MailerLite
• Large list + low sending frequency → Brevo
• You want sophisticated ecommerce segmentation and automation → Klaviyo
• Don't start with ActiveCampaign unless you already know you need complex automation.
• I wouldn't choose Mailchimp on a tight budget; its pricing tends to become less attractive as your list grows. www.hostinger.comtajo.iowww.drip.comsaasprobe.com

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Etsy + website, etc.), roughly how many subscribers you have, and how many emails you expect to send per month, I can tell you which one is likely to be cheapest for your specific situation.

For a small ecommerce site on a tight budget, I’d usually start with an ecommerce-focused email platform rather than a general newsletter tool. The best choice depends on your store size and platform (Shopify, WooCommerce, etc.), but these are the strongest options: www.emailtooltester.comwww.omnisend.com

My recommendation by situation

If you’re on Shopify and want abandoned carts, welcome flows, post-purchase emails, and win-back campaigns:
→ Start with Omnisend. It’s built around ecommerce use cases, has prebuilt automation templates, and is generally positioned as a more affordable alternative to Klaviyo. www.mailercloud.com

Your first automations should be:

1. Welcome series
   • Email 1: brand introduction + incentive
   • Email 2: best sellers/social proof
   • Email 3: customer stories or product education

2. Abandoned cart
   • Reminder after a few hours
   • Follow-up 1–2 days later

3. Post-purchase
   • Thank you/order tips
   • Review request
   • Cross-sell recommendation

4. Win-back
   • “We miss you” email after 60–90 days

If you have fewer than ~1,000 subscribers and mostly want newsletters:
→ MailerLite is probably enough. You can upgrade later when automation becomes a revenue channel.

If you’re already doing strong revenue and need advanced segmentation:
→ Klaviyo is the premium choice. It has deeper customer data and segmentation, but many small stores won’t use enough of its advanced features to justify the cost early on. www.omnisend.com

A simple stack I’d pick for a new small ecommerce brand:

• Shopify + Omnisend (most cases)
• Shopify + MailerLite (ultra lean)
• Shopify + Klaviyo (if you’re already scaling)

If you tell me:

1. your ecommerce platform (Shopify/WooCommerce/etc.),
2. your monthly orders, and
3. your email list size,

I can narrow it down to the cheapest option that won’t box you in.

For a small ecommerce site on a tight budget, I’d usually narrow it down to three choices:

www.emailtooltester.com

My recommendation by situation:

If you’re under ~1,000–5,000 subscribers: start with MailerLite

MailerLite

Good for:

• weekly newsletters
• welcome sequences
• discount campaigns
• basic customer tagging
• simple automations

It’s lightweight and you won’t spend days learning it.

If you’re on Shopify and want sales automation: use Klaviyo

Klaviyo

This is the ecommerce specialist. It’s strongest for:

• abandoned cart emails
• browse abandonment
• post-purchase sequences
• product recommendations
• VIP/customer segments
• revenue tracking

It costs more, but ecommerce brands often move there once email becomes a meaningful sales channel.

If your budget is extremely tight: use Brevo

Brevo

Brevo is attractive because it focuses on send volume rather than just charging more as your contact list grows. It can work well if you have a large list but don’t email constantly.

For most small ecommerce stores, I’d set up these automations first:

1. Welcome series
   • Email 1: brand story + incentive
   • Email 2: best sellers/social proof
   • Email 3: customer education or product tips

2. Abandoned cart
   • 1 hour reminder
   • 24 hour reminder
   • 3–5 day incentive (optional)

3. Post-purchase
   • Thank you
   • How to use the product
   • Review request
   • Cross-sell

4. Win-back
   • “We miss you”
   • New product or offer

My default pick:

• Shopify + serious growth goal → Klaviyo
• Tiny budget + under a few thousand customers → MailerLite
• Need maximum cost control → Brevo

If you tell me your ecommerce platform (Shopify, WooCommerce, Squarespace, etc.), monthly revenue, and current email list size, I can narrow it to one choice.
