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.

Brevo pricing

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

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:

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.
