If you're a small online store and want discount codes, abandoned-cart emails, and customer segmentation without paying for lots of add-ons, I'd narrow it to three options:

*Pricing/features can change by plan and store platform. Shopify's current comparison lists Shopify Messaging at 10,000 free emails/month, Omnisend from $16/month, and Klaviyo from $15/month. Shopify Liquid Lemon

My practical take

• If you're on Shopify and are very small: Shopify Messaging is the cheapest/simple route. It already has native store data, abandoned-cart functionality, and no separate integration to maintain. Shopify says its native system includes 10,000 free emails/month. Shopify
• If you want more sophisticated segmentation without jumping to Klaviyo pricing: Omnisend is probably the sweet spot. It is ecommerce-focused and has native abandoned-cart workflows, segmentation, and email/SMS in the same system. Shopify First Reviewers
• If segmentation and behavioral targeting are going to become a major part of your marketing: Klaviyo gives you considerably deeper customer/order/cart segmentation and sophisticated automated flows, but its pricing becomes more noticeable as your contact list grows. Shopify stackfyi.com

For your specific requirements, I'd start with Omnisend if you're willing to spend ~$16/month. It hits the middle ground: ecommerce-native automation, abandoned carts, segmentation, and discount-driven campaigns without having to stitch together several services.

If you're already on Shopify and have a very small list, I'd first try Shopify Messaging because you may not need to pay anything yet.

If you tell me Shopify, WooCommerce, Etsy, or another platform + roughly how many subscribers you have, I can compare the actual monthly cost of the 2–3 cheapest choices for your store.

For a small online store, I’d focus on native ecommerce features rather than the cheapest newsletter tool. The expensive part is usually not sending emails — it’s paying for integrations (Zapier, custom apps, developer work) to make abandoned carts, customer segments, and discount codes work. StackFYI

Here are the strongest affordable options:

My shortlist for a small store

If you use Shopify:

1. Omnisend — probably the first one I’d test. It is built around ecommerce workflows, so you can usually avoid stitching together multiple apps. Sequenzy
2. Klaviyo — choose this if you expect to build sophisticated segments like “customers who bought product X twice but haven’t purchased in 90 days.” BestSends

If your budget is very tight:

• Brevo is worth considering because you can keep costs lower as your contact list grows. SMB Compare

Minimum automations I’d set up first

Regardless of platform:

1. Welcome series

• Email 1: brand introduction + first-order discount
• Email 2: best sellers/social proof
• Email 3: reminder before discount expires
• Abandoned cart

• 1 hour: reminder
• 24 hours: product benefits + customer reviews
• 48–72 hours: optional discount code
• Post-purchase

• Thank you/order tips
• Review request
• Cross-sell or repeat purchase offer
• Segments

• First-time buyers
• Repeat customers
• High spenders
• Customers who haven’t purchased in 60–90 days
• Browsed product but didn’t buy

If you tell me your store platform (Shopify, WooCommerce, Etsy, Wix, Squarespace, etc.) and roughly how many subscribers/customers you have, I can narrow this to the cheapest option that won’t force you into paid integrations.

For a small online store, Omnisend is probably the closest fit to what you described.

• Omnisend — ecommerce-focused, with built-in abandoned-cart workflows, store-linked discount codes, and behavioral/purchase-based segmentation. Its Standard plan is currently listed at $16/month, with a free tier for very small lists. Omnisend Omnisend
• Brevo — potentially cheaper if you send lots of emails, because pricing is more send-volume-oriented. It supports ecommerce automation and abandoned-cart flows, but its ecommerce segmentation/workflows aren't as store-focused as Omnisend. Omnisend
• MailerLite — inexpensive and easy to use, but better suited to simpler ecommerce/email needs. Its segmentation is less ecommerce-specific, so I'd choose it only if advanced customer targeting isn't important. Omnisend
• Klaviyo — very capable for abandoned carts and granular segmentation, but its pricing scales with your contact list and is generally harder to justify for a small store on a tight budget. Omnisend

My pick

Omnisend if you want discount codes + abandoned carts + segmentation with minimal integration work. It connects directly to major ecommerce platforms and is designed around store events such as purchases and abandoned carts, rather than requiring you to stitch together multiple services. Omnisend

If you tell me whether your store is Shopify, WooCommerce, Etsy, etc. and roughly how many email subscribers you have, I can narrow it down to the cheapest suitable option and estimate the monthly cost.

Omnisend is probably the best fit for a small online store. It includes discount codes, abandoned-cart automations, and unlimited segmentation, with ecommerce integrations built in rather than requiring costly third-party connectors. Omnisend Omnisend

• Free: $0, up to 250 contacts/500 emails monthly.
• Standard: starts at $16/month normally ($11.20 for the first 3 months currently).
• Especially good if you sell through Shopify or another major ecommerce platform. support.omnisend.com

Bottom line: I'd choose Omnisend over a general email platform if ecommerce automation is your priority. support.omnisend.com

For a small ecommerce store, Omnisend is probably the best fit if your priority is getting discount codes, abandoned-cart automation, and segmentation without stitching together several paid apps.

• Abandoned carts: Built-in abandoned-cart and abandoned-checkout workflows. Omnisend Help Center
• Discount codes: It can automatically generate unique codes for Shopify, BigCommerce, and WooCommerce. Omnisend Help Center
• Segmentation: Included on all plans, with targeting based on purchases, engagement, profile data, discount-code usage, and more. Omnisend Omnisend Help Center
• Integrations: Shopify, WooCommerce, and BigCommerce have native integrations, so you don't need a third-party automation service just to connect your store. Omnisend
• Price: Omnisend currently has a free tier for up to 250 contacts/500 emails per month. Its Standard plan starts at $16/month, with a current new-subscriber promotion of 30% off for the first three months. Omnisend Omnisend Help Center

Brevo is another inexpensive option and can handle cart-triggered automations and coupon-code sequences, but for a straightforward ecommerce store, I'd lean toward Omnisend because the ecommerce functionality is more purpose-built. Brevo Help Brevo Help

My pick: Omnisend if you're on Shopify/WooCommerce/BigCommerce and want one relatively inexpensive tool instead of paying for multiple integrations.

omnisend.com

For a small online store, I’d pick Omnisend.

Why it fits your requirements particularly well:

• Discount codes: It can automatically generate unique discount codes for Shopify, BigCommerce, and WooCommerce. Omnisend Help Center
• Abandoned carts: Built-in abandoned-cart and abandoned-checkout workflows are included, so you don't need a separate automation service. Omnisend Help Center
• Segmentation: Unlimited segmentation based on purchases, browsing, engagement, customer lifecycle, and other store data. Omnisend
• Low starting cost: The free plan supports up to 250 contacts and 500 emails/month. The Standard plan starts at $16/month normally, with a current first-3-month introductory price of $11.20/month. Omnisend Help Center Omnisend
• Minimal integration hassle: Omnisend has direct ecommerce data connections, including real-time Shopify and WooCommerce syncing, rather than requiring you to stitch together several services. Omnisend

My recommendation

Start with Omnisend Free if you're under 250 contacts. Once you're consistently sending more, move to Standard.

I'd choose Omnisend over Brevo for your particular use case because your priorities are ecommerce automation + cart recovery + store-linked discounts + segmentation, rather than simply sending inexpensive newsletters. Brevo is cheaper to start at $9/month, but Omnisend is more purpose-built around ecommerce workflows. Brevo Help

If you tell me whether your store is Shopify, WooCommerce, Etsy, or something else, I can also tell you the cheapest option for your exact platform.

Best fit: Omnisend

For a small ecommerce store, I’d pick Omnisend over Klaviyo if your priority is getting ecommerce features without paying for lots of integrations.

• Abandoned-cart emails: built-in, preconfigured workflows.
• Discount codes: can be linked directly to your store.
• Segmentation: customer behavior, purchases, engagement, and lifecycle stages.
• Store integration: native ecommerce integrations, so you don't need to stitch together Zapier-style integrations for the basics.
• Price: the Standard plan starts around $16/month, with a free tier for very small lists. Omnisend Omnisend

How I'd rank the budget options

MailerLite can be cheaper—around $10–$15/month at small contact counts—but Omnisend has a much stronger ecommerce feature set out of the box, including discount codes and cart recovery. Omnisend Omnisend

My recommendation: If you're on Shopify or another mainstream ecommerce platform and have, say, under 5,000 subscribers, start with Omnisend. You get the three things you specifically asked for—discount-driven campaigns, abandoned carts, and segmentation—without building a complicated integration stack.

If you tell me your store platform (Shopify, WooCommerce, Etsy, etc.) and roughly how many email subscribers you have, I can narrow it down to the cheapest option for your exact situation.

For a small online store, Omnisend is probably the best fit if your priority is getting ecommerce automation without paying for a pile of integrations.

My shortlist

• omnisend.com — best overall value. It has native ecommerce workflows for abandoned carts, segmentation based on behavior/purchase history, and discount offers in signup forms. Its Standard plan is around $16/month at the entry level, according to 2026 pricing comparisons. Omnisend Omnisend
• brevo.com — best budget alternative. Particularly attractive if your list is growing but your email volume is relatively modest. It supports abandoned-cart sequences, conditional segmentation, and even unique coupon codes based on cart value. Brevo Help
• klaviyo.com — best features, but probably overkill initially. Its segmentation and ecommerce data are excellent, including dynamic coupons and sophisticated abandoned-cart flows, but pricing rises faster as your customer list grows. Klaviyo Help Center Klaviyo Help Center

My pick: Start with Omnisend if you're on Shopify/WooCommerce and want the simplest "connect store → turn on flows → segment customers → send discounts" setup. Independent 2026 comparisons also put it ahead of Klaviyo on value for smaller ecommerce businesses. techsifted.com Omnisend

If you tell me your platform (Shopify, WooCommerce, Etsy, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest option and estimate your monthly cost.

For a small online store, I’d shortlist Brevo and Omnisend rather than jumping straight to Klaviyo.

• Brevo — best budget pick. It supports abandoned-cart sequences, discount/promo codes, and customer segmentation, while using relatively inexpensive send-based pricing. Brevo specifically supports inserting coupon codes into abandoned-cart emails. Brevo Help EmailTooltester.com
• Omnisend — best if you're Shopify-focused. It’s purpose-built for ecommerce, with native store integrations, abandoned-cart automation, segmentation, and email/SMS. Pricing reported for 2026 starts around $20/month for 1,000 contacts. Omnisend StackFYI
• Klaviyo — best features, but probably overkill initially. Its segmentation and ecommerce automation are excellent, but pricing scales with contacts and can become substantially more expensive. TechSifted StackFYI

My pick

Start with Brevo if keeping costs down is the priority. It gives you the three things you specifically asked for—discount codes + abandoned-cart emails + segmentation—without requiring a pile of separate integrations.

If your store is on Shopify and you want the easiest ecommerce-specific experience, I'd lean Omnisend instead.

If you tell me your ecommerce platform (Shopify, WooCommerce, Etsy, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest option and estimate your monthly cost.

For a small online store, I’d pick omnisend.com as the best balance of price and ecommerce features.

*Prices can vary by contacts, billing, and plan. Current 2026 comparisons put Omnisend at $16/month, MailerLite at $10, and Klaviyo at $20 at their respective entry tiers. Omnisend Omnisend

Why I'd choose Omnisend

It is specifically designed around ecommerce rather than being a generic newsletter platform. It supports abandoned-cart and abandoned-checkout automations, audience segmentation, and ecommerce features such as store-linked discount codes without requiring you to stitch together multiple expensive services. Omnisend Omnisend Help Center

It also has a free tier that includes campaigns, automations, forms, and segmentation, although it's limited to 250 contacts and 500 emails/month. Omnisend

My ranking for your use case:

1. 🥇 Omnisend — best overall if you're selling physical products.
2. 🥈 MailerLite — best if keeping the monthly bill as low as possible matters more than advanced ecommerce features.
3. 🥉 Klaviyo — best if you expect to grow into sophisticated customer segmentation and analytics, but you're paying more for it.

If you're on Shopify, I'd lean even more strongly toward Omnisend because its ecommerce workflows are designed around the store data rather than requiring a pile of separate integrations. smbcompare.com

If you tell me roughly how many customers/subscribers you have (e.g. 500, 2,000, or 10,000) and whether you're on Shopify, WooCommerce, or something else, I can tell you which is actually cheapest for your store.

It also has a free tier that includes campaigns, automations, forms, and segmentation, although it's limited to 250 contacts and 500 emails/month.

My ranking for your use case:

For a small ecommerce store, I’d pick Omnisend first.

Why Omnisend stands out

• Discount codes are native: it can generate unique coupons directly inside emails; Shopify, BigCommerce, and WooCommerce can have codes automatically generated/applied. www.omnisend.com
• Abandoned-cart emails are ready-made: Omnisend provides abandoned-cart and abandoned-checkout automations rather than requiring you to build the integration yourself. support.omnisend.com
• Segmentation is ecommerce-focused: you can segment by purchases, browsing/engagement, discount-code use, demographics, tags, and other shopping behavior. support.omnisend.com
• Pricing is relatively approachable: its Free plan allows 500 emails/month to up to 250 contacts, while Standard currently starts at $16/month. support.omnisend.com

One caveat: Omnisend's billing counts some non-subscribed contacts—including abandoned-cart contacts—toward billable contacts, so watch your contact count as the store grows. support.omnisend.com

My recommendation: If you're on Shopify/WooCommerce/BigCommerce and want “everything in one place” without stitching together several apps, start with Omnisend. If your store is very small and email volume is your main concern, Brevo is worth comparing—it starts at $0 and its paid plans start at $9/month. help.brevo.com

If you tell me which ecommerce platform you use (Shopify, WooCommerce, Etsy, etc.) and roughly how many customers/emails you have, I can narrow it down to the cheapest option for your store.

For a small ecommerce store, I’d pick Omnisend first.

omnisend.com is specifically built for ecommerce, so you get the important pieces without stitching together several apps:

• Abandoned-cart and checkout emails — built-in workflows, including conditional discount offers. Omnisend Help Center
• Discount codes — store-linked discount codes can be used directly in campaigns/automations. Omnisend
• Segmentation — based on purchase history, behavior, engagement, and other customer data. Omnisend
• Ecommerce integrations — designed to connect directly with platforms such as Shopify and WooCommerce rather than requiring a complicated integration stack. Omnisend
• Low starting cost — there's a free plan for up to 250 contacts, with paid Standard plans starting around $16/month in 2026. Fit Small Business

How I'd rank the options

MailerLite is worth considering if absolute price is your priority—it starts lower, but Omnisend has the stronger ecommerce-native feature set, particularly around cart recovery and store-linked discounts. Omnisend Omnisend

Klaviyo is excellent, but I'd avoid starting there unless you need sophisticated customer analytics and segmentation. Its strength is depth, not necessarily simplicity or lowest cost. Klaviyo Help Center

Bottom line: If you tell me whether your store runs on Shopify, WooCommerce, Wix, or something else, I can tell you the cheapest plan that gives you all three—discount codes + abandoned cart + segmentation—with minimal/no extra integration costs.

For a small online store, Omnisend is probably the best fit for what you described.

My pick: Omnisend

Omnisend is particularly attractive because the ecommerce functionality is built in rather than requiring you to stitch together several services. Its workflows include cart-abandonment automation, and it supports ecommerce features such as store-linked discount codes, customer segmentation, product recommendations, and post-purchase flows. Omnisend Omnisend

The current free tier is 500 emails/month for up to 250 contacts. Its Standard plan starts at $16/month, with a current first-three-month promotional price of $11.20/month when eligible. Omnisend Help Center Omnisend

If you're on Shopify

I'd also seriously consider Shopify Messaging/Email if your store is still small. Shopify reports that Shopify Messaging can handle email and SMS campaigns directly from your Shopify admin, and current comparisons show Shopify Email as free for up to 10,000 emails/month. Shopify Omnisend

That's potentially the cheapest/no-integration option, but Omnisend gives you a more sophisticated segmentation and automation environment as you grow.

Bottom line:

• Cheapest + simplest: Shopify Email, if you're on Shopify.
• Best balance of price + ecommerce automation: Omnisend.
• Most powerful segmentation: Klaviyo, but I'd avoid paying for that complexity until your store needs it.

If you tell me your ecommerce platform (Shopify, WooCommerce, Etsy, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest option for your specific store.

For a small online store, I’d put Omnisend at the top of the list.

*Pricing varies by contacts/plan; these are recent published starting points. Omnisend Omnisend

Why I’d choose Omnisend

Omnisend is purpose-built for ecommerce, so the features you listed are native rather than something you have to stitch together:

• Abandoned-cart flows and other prebuilt ecommerce automations.
• Behavioral segmentation based on purchases and shopping activity.
• Discount codes connected to your store, rather than manually creating coupons and importing them.
• Product recommendations and product-picking directly from your catalog.
• Native integrations with major ecommerce platforms such as Shopify, WooCommerce, and BigCommerce.
• Email + SMS/push options if you eventually want to expand. Omnisend SleekFlow

That makes it particularly attractive if your priority is “I want this working without paying for a bunch of Zapier-style integrations.”

When I'd pick something else

MailerLite if your store is tiny and you mainly need newsletters, basic segmentation, and straightforward automations. It's cheaper, but its ecommerce capabilities aren't as deep as Omnisend's. Omnisend

Klaviyo if you're expecting to grow substantially and want the most sophisticated customer segmentation, analytics, and lifecycle automation. It's excellent, but the pricing can climb as your contact list grows. Omnisend StackFYI

Bottom line: For a small ecommerce business wanting discounts + abandoned carts + segmentation + minimal integration hassle, I'd start with Omnisend. It's probably the best balance between ecommerce functionality and cost right now. Omnisend

For a small ecommerce store, Omnisend is probably the best fit for what you described.

• Abandoned-cart emails: Built-in prebuilt workflows, so you don't need to stitch together a separate automation service. Omnisend Omnisend
• Discount codes: It can automatically generate unique coupons; with Shopify, coupons can be automatically applied at checkout. Omnisend
• Segmentation: Included even on the free plan, with segments based on purchase history, browsing/behavior, engagement, discount-code usage, etc. Omnisend Omnisend Help Center
• Cost: The current free plan supports up to 250 contacts and 500 emails/month. Standard starts at $16/month normally, with a current introductory price of $11.20/month for the first three months when paying three months upfront. Omnisend Help Center
• Integrations: It's designed specifically around ecommerce data and offers real-time store syncing, which is much less cumbersome than assembling generic email + automation + coupon tools. Omnisend

My pick

Start with Omnisend Free if you're under 250 contacts. Once you outgrow it, Standard is the tier I'd consider first. I wouldn't jump straight to Klaviyo unless you need its deeper analytics/customization and are comfortable paying more.

omnisend.com

If you tell me what platform your store uses (Shopify, WooCommerce, Etsy, Squarespace, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest 2–3 options for your specific setup.

For a small ecommerce store, I’d put Omnisend at the top of the list—especially if you’re on Shopify.

Best fit: Omnisend

omnisend.com is unusually well matched to your requirements because ecommerce features are built in rather than requiring you to stitch together several apps.

• Abandoned-cart emails: built-in abandoned cart and abandoned checkout automations. Omnisend Help Center
• Discount codes: supports dynamic coupon codes, including in automated campaigns. Shopify
• Segmentation: audience segmentation is built in, so you can target customers by behavior, purchases, etc. Shopify
• Low starting cost: currently $0 for up to 250 contacts/500 emails monthly, with Standard starting at $16/month. Omnisend Help Center
• Minimal integration work: it has a native ecommerce/Shopify connection and prebuilt workflows, so you aren't paying for Zapier-style glue between separate services. Shopify

How I'd compare the alternatives

One important alternative is Shopify Messaging if your store is on Shopify. It includes 10,000 emails/month, native cart-data syncing, abandoned-cart automations, discount-code support, and customer segmentation directly inside Shopify—so you may not need another email platform at all. Shopify

My recommendation:

• Shopify + very small list: start with Shopify Messaging and spend $0 on another platform.
• Shopify + you want more sophisticated ecommerce automation: choose Omnisend.
• You expect complex customer journeys/very advanced segmentation: consider Klaviyo, but you're more likely to pay for capabilities you don't yet need.

If you tell me your ecommerce platform (Shopify, WooCommerce, Wix, etc.) and roughly how many email subscribers you have, I can narrow it down to the cheapest option for your specific store.

For a small online store, I’d prioritize a tool that is built for ecommerce flows (cart recovery + customer behavior data) rather than a general newsletter platform. The best affordable choices are usually:

SMB Compare StackFYI### My shortlist

1. Best overall: Omnisend

• Good fit if you sell through Shopify, WooCommerce, or another ecommerce platform.
• Includes abandoned cart automation, welcome series, customer segments, and promotional campaigns without needing a stack of extra apps. Omnisend
• Usually cheaper than Klaviyo for a growing small store. SMB Compare

2. Best if you want advanced marketing: Klaviyo

• Choose this if you want deeper segmentation like: - “customers who bought product A but not product B”
• “high-value customers who haven’t purchased in 90 days”
• detailed lifecycle campaigns
• It’s powerful, but pricing can rise as your contact list grows. SMB Compare

3. Best ultra-budget route: Shopify Email + a simple cart recovery app

• Fine if you are just starting and mainly need newsletters and basic promotions.
• You may outgrow it once you want sophisticated abandoned cart sequences and customer targeting. Shopify

What I would pick by store size

• 0–1,000 subscribers: Omnisend or Shopify Email
• 1,000–10,000 subscribers: Omnisend (best cost/features ratio)
• Growing brand with repeat purchases: Klaviyo
• Very price-sensitive: Brevo or an ecommerce-focused low-cost tool

A key thing to avoid: using a cheap email sender plus separate apps for carts, coupons, popups, and segmentation. Those integrations often become more expensive and fragile than paying slightly more for one ecommerce-focused platform. sequenzy.com

If you tell me your platform (Shopify, WooCommerce, Etsy, Wix, Squarespace, etc.) and your approximate subscriber count, I can narrow it to the cheapest option that still covers all three needs.

For a small online store, Omnisend is probably the best fit for what you described.

Why I'd pick Omnisend

• Built specifically for ecommerce, rather than being primarily a newsletter platform.
• Has pre-built abandoned-cart and abandoned-checkout workflows, so you don't need to construct them from scratch. Omnisend Help Center Omnisend
• Supports discount codes tied to your store and segmentation based on purchase history and customer behavior. Omnisend Omnisend
• Its integrations are designed to connect directly to ecommerce platforms, avoiding the need for third-party connectors. Omnisend
• The current Standard plan starts at $16/month, while the free plan includes the core feature set but is limited to 500 emails/month and 250 contacts for campaigns. Omnisend Help Center

The sweet spot: if you're on Shopify/WooCommerce and have a few hundred to a few thousand customers, I'd choose Omnisend Standard before paying for Klaviyo. Current comparisons put Omnisend below Klaviyo at common contact levels while retaining the ecommerce features you actually need. Omnisend

One caveat: Omnisend's pricing counts some non-subscribers—such as abandoned-cart contacts—as billable contacts, so watch your contact count as the store grows. Omnisend Help Center

If you tell me which store platform you use (Shopify, WooCommerce, Etsy, Wix, etc.) and roughly how many subscribers you have, I can tell you the cheapest option that gives you all three features without extra integrations.

For a small online store, I’d prioritize native ecommerce features over a cheap newsletter tool. The big money-saving features are: built-in abandoned cart flows, discount-code support, customer segments based on purchases, and direct Shopify/WooCommerce connections (so you don’t pay for Zapier-style integrations). Sequenzy StackFYI

Here are the best affordable options:

SMB Compare StackFYI### My picks by store size

• Under ~1,000 subscribers: omnisend.com is probably the best balance. You get abandoned-cart automation, segments, and ecommerce workflows without building a complicated stack. Sequenzy
• Just starting and watching every dollar: brevo.com is worth considering because it combines marketing automation and transactional email at a lower cost. Email Tool Tester
• Growing brand with repeat customers and lots of data: klaviyo.com is usually the upgrade path because its segmentation is much deeper. US Tech Automations

For your specific requirements — discount codes + abandoned cart emails + segmentation without costly integrations — I would start with:

1. Omnisend → best overall fit for a small ecommerce shop
2. Brevo → best budget choice
3. Klaviyo → only if you expect fast growth and can justify the higher cost

If you tell me your store platform (Shopify, WooCommerce, Etsy, Wix, Squarespace, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest option that still has all three features.

If you tell me your store platform (Shopify, WooCommerce, Etsy, Wix, Squarespace, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest option that still has all three features.

For a small online store, Brevo looks like the best budget-first fit if your priorities are discount codes + abandoned-cart emails + segmentation without stitching together lots of apps.

My shortlist

• Brevo — best budget choice. It supports abandoned-cart automations, conditional segmentation, and coupon codes—including unique codes when using a compatible ecommerce plugin/API. Brevo Help SMB Compare
• Omnisend — best if ecommerce is your main focus. It is more purpose-built for online stores, with native ecommerce automation, abandoned-cart sequences, discount codes, and segmentation. Its pricing is still relatively reasonable for small lists. Omnisend Omnisend
• MailerLite — best for simplicity. It's inexpensive and easy to use, and supports ecommerce/cart-abandonment workflows, but its ecommerce automation depth is less impressive than Omnisend. MailerLite Omnisend
• Klaviyo — best features, not my budget pick. It has excellent ecommerce segmentation and flows, but you're more likely to pay for that sophistication as your customer list grows. SMB Compare

My pick: Start with Brevo if keeping monthly costs and integrations low is the priority. Choose Omnisend instead if you're on Shopify/WooCommerce and expect email automation to become a major sales channel.

One important distinction: if by “without costly integrations” you mean you want the email platform to connect directly to your Shopify/WooCommerce store, tell me which platform you use. I can narrow this down to the cheapest option that gives you all three features natively.

For a small ecommerce store, omnisend.com would be my first pick.

It hits the combination you care about—discount codes + abandoned-cart emails + segmentation + low integration hassle—without requiring a stack of third-party connectors.

Omnisend specifically supports store-linked discount codes, cart recovery, behavioral/purchase-based segmentation, and prebuilt ecommerce automations. Its current Standard plan starts around $16/month, while it also has a free tier. Omnisend Omnisend

Why I'd choose Omnisend

The important distinction is that you don't just want a cheap newsletter platform. You want the email system to understand products, carts, purchases, and customer behavior. Omnisend is built around those ecommerce events, so you can set up things like:

• Welcome email → discount code
• Abandoned cart → reminder → discount incentive
• Customers who bought Product A → cross-sell Product B
• VIP/high-spend customers → special offer
• Customers who haven't purchased in 90 days → win-back discount

That can largely be done through the platform's native ecommerce integration rather than stitching together separate automation services. Omnisend SleekFlow

Klaviyo is arguably better if you eventually need extremely sophisticated segmentation and predictive analytics, but for a small store I'd hesitate to pay the premium until you actually need that complexity. Current comparisons put Omnisend below Klaviyo on advanced segmentation while still covering the core ecommerce workflows. Omnisend Omnisend

Bottom line: Start with Omnisend if ecommerce automation is the priority; choose MailerLite only if your main goal is the absolute lowest-cost basic email marketing and your store automation needs are modest. Omnisend

If you tell me whether you're on Shopify, WooCommerce, Etsy, or another platform and roughly how many subscribers you have, I can narrow it down to the cheapest option for your particular store.

For a small ecommerce store, omnisend.com is probably the best fit for what you described.

Omnisend specifically includes prebuilt abandoned-cart automations, shopping-behavior segmentation, and automatically generated/synchronized discount coupon codes. Omnisend Omnisend Help Center

The Free plan gives you the same core feature set but limits you to 250 contacts and 500 emails/month. The Standard plan starts at $16/month and scales with your contact count. Omnisend Help Center

Why I'd pick it over the alternatives

• Klaviyo: excellent, particularly if you need extremely sophisticated segmentation, but it's generally harder to justify for a tiny store.
• Brevo: cheaper starting price (from $9/month) and good general-purpose email marketing, but Omnisend is more purpose-built around ecommerce workflows. Brevo Help
• Mailchimp: easy to start with, but ecommerce automation and coupon/segmentation workflows can become less attractive as your store grows.

Bottom line: If your priority is “I want abandoned carts + discount codes + useful segments without stitching together several apps,” I'd start with Omnisend. Its ecommerce features are native enough that you shouldn't need costly third-party automation just to get the basics running.

For a small online store, I’d prioritize built-in ecommerce features over the cheapest newsletter tool. You want:

• Discount-code automation
• Abandoned cart recovery

• Store integration without paying for Zapier/extra connectors

My shortlist:

Omnisend SMB Compare## My recommendation for a small store: Omnisend

Omnisend is usually the best fit if you want revenue-focused email without building a complicated tech stack. It is designed around ecommerce workflows, so you can typically connect your store directly and create:

• Welcome series with first-order discount codes
• Abandoned cart sequences
• Post-purchase follow-ups
• Customer segments (VIP buyers, repeat customers, inactive shoppers, etc.)
• Product-based campaigns

It is generally positioned as a lower-cost alternative to Klaviyo while keeping ecommerce automation features. Omnisend Chase Dimond

When I’d choose Klaviyo instead

Pick Klaviyo if you already have meaningful sales volume and want very detailed segments, such as:

• “Customers who bought product A but never product B”
• “High spenders who haven’t purchased in 90 days”
• “Browsed twice but didn’t buy”

Klaviyo’s segmentation and customer data tools are stronger, but the pricing can become harder to justify for a small shop. SMB Compare Choose My Stack

When Mailchimp makes sense

Mailchimp is fine if your main goal is:

• Occasional newsletters
• Basic promotions
• Simple customer emails

For a product store that depends heavily on abandoned-cart recovery and targeted offers, it is usually less specialized than Omnisend or Klaviyo. Omnisend

A simple setup I’d use for a small store

1. Omnisend
2. Connect your store directly (Shopify, WooCommerce, etc.)
3. Create: - Welcome email → 10% discount code
4. Abandoned cart flow → 2–3 emails
5. Post-purchase thank-you → review request
6. VIP segment → exclusive offers
7. Win-back flow → “we miss you” discount

That gives you most of the email revenue opportunities without stacking expensive integrations.

If you tell me your platform (Shopify, WooCommerce, Etsy, Squarespace, Wix, etc.) and approximate list size, I can narrow it down to the cheapest option that still covers everything.

For a small ecommerce store, Omnisend would be my first choice—especially if you're on Shopify, WooCommerce, or BigCommerce.

• Abandoned-cart emails: Built in, with prebuilt automation workflows. Shopify connects directly and syncs customer/product/order data without a separate integration service. Omnisend Help Center Omnisend Help Center
• Discount codes: Omnisend can automatically generate unique, trackable discount codes for Shopify, BigCommerce, and WooCommerce, so you don't have to create codes manually. Omnisend Help Center Omnisend Help Center
• Segmentation: Available on all plans, including behavioral and purchase-based segments. Omnisend Help Center
• Cost: The free plan allows up to 250 contacts and 500 emails/month. The current Standard plan starts at $16/month, with a temporary 30% new-subscriber discount when paying three months upfront. Omnisend Omnisend Help Center
• Minimal integration hassle: Shopify, WooCommerce, BigCommerce, Wix and several others have native integrations; most can be connected without coding. Omnisend Help Center

Why I'd choose it over MailerLite

omnisend.com is more ecommerce-focused. MailerLite is inexpensive and has excellent general-purpose segmentation, but its current Shopify integration specifically does not support abandoned-cart email automations—only abandoned checkout triggers. mailerlite.com

Bottom line: If your must-haves are discount codes + abandoned cart + segmentation + little/no integration overhead, Omnisend is probably the best value for a small store right now.

If you tell me your ecommerce platform (Shopify, WooCommerce, Wix, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest 2–3 options and show the likely monthly cost.

For a small online store, I’d look first at Omnisend or Brevo rather than jumping straight to expensive tools. The best fit depends on how important ecommerce automation is for you. smbcompare.comwww.emailtooltester.com

My recommendation by store size

If you have under ~5,000 subscribers and want minimal setup:
→ Omnisend

• Built around ecommerce use cases (cart recovery, product recommendations, customer segments).
• You usually won’t need Zapier or extra connectors because store integrations are a core feature. smbcompare.comwww.emailtooltester.com

If your priority is keeping monthly costs as low as possible:
→ Brevo

• Good if you need email + basic CRM features and don’t need extremely advanced ecommerce targeting. smbcompare.comwww.emailtooltester.comwww.shopify.com

If you’re already doing significant sales volume:
→ Klaviyo

• Best for segments like “customers who bought X but haven’t bought in 90 days” or “high-value customers who viewed a product twice.” ustechautomations.com
• The downside is pricing tends to rise as your contact list grows. smbcompare.com

For a typical small Shopify/WooCommerce shop, I’d choose:

1. Omnisend — best balance of cost + ecommerce features
2. Brevo — cheapest practical option
3. Klaviyo — upgrade later when revenue justifies it

A good starter setup would be:

• Welcome email → 10% discount code
• Abandoned cart sequence → 1 hour / 24 hour / 72 hour reminders
• Repeat customer segment → VIP offers
• Past customer segment → win-back discount

That gives you most of the revenue impact without paying for a complex marketing stack. smbcompare.comwww.emailtooltester.com

For a small online store, Omnisend is probably the best fit for what you described.

My pick: Omnisend

omnisend.com is particularly ecommerce-focused, so you get the important pieces without having to stitch together several apps:

• Abandoned-cart automation and other ecommerce workflows are built in.
• Segmentation can use purchases, browsing/engagement behavior, signup source, tags, demographics, and discount-code usage. Omnisend Omnisend Help Center
• Unique discount codes can be generated directly in emails. For Shopify, BigCommerce, and WooCommerce, Omnisend can sync the codes with your store rather than requiring a separate integration. Omnisend Omnisend Help Center
• Pricing currently starts at $16/month for Standard, while the free plan includes the main features but is limited to 250 contacts and 500 emails/month. Omnisend Help Center
• There's currently a 30% first-three-month discount when a new paid customer pays three months upfront. Omnisend Help Center

How I'd rank the alternatives

Brevo starts at $9/month, and its automation can handle abandoned carts and coupon codes, but setting up ecommerce tracking/coupon functionality can require more configuration—for example, Brevo's abandoned-cart workflow requires its tracker and specific ecommerce events. Brevo Help Brevo Help

Bottom line: If you're on Shopify, WooCommerce, or BigCommerce, I'd choose Omnisend. It gives you the combination you specifically want—discount codes + abandoned carts + segmentation + ecommerce automation—with relatively little integration work.

One caveat: Omnisend's paid pricing counts both subscribers and certain non-subscribers, including people who abandon carts, so watch your billable-contact count as your store grows. Omnisend Help Center

If you tell me what platform your store uses (Shopify, WooCommerce, Wix, Squarespace, etc.) and roughly how many email subscribers you have, I can tell you which option is likely to be cheapest for your specific store.

For a small online store, I’d pick Omnisend. It’s particularly well suited to ecommerce because the features you want are native rather than requiring a stack of paid integrations.

Best fit: omnisend.com

• Abandoned-cart emails: Built-in ecommerce workflows handle cart abandonment, welcome sequences, post-purchase and re-engagement. Omnisend
• Discount codes: It can generate unique coupons automatically and sync them with Shopify, BigCommerce, and WooCommerce, so you don't have to create codes manually. Omnisend Omnisend Help Center
• Segmentation: Segmentation is available on all plans, using purchase history, browsing behavior, engagement, demographics and other customer data. Omnisend Help Center
• Low starting cost: There's a free plan for up to 250 contacts/500 emails per month. The Standard plan starts at $16/month at regular pricing, with a current introductory offer of 30% off for the first three months when paying three months upfront. Omnisend Omnisend Help Center
• Minimal integration hassle: For mainstream ecommerce platforms, the key store data and coupon functionality are designed to work directly with the platform rather than requiring separate automation tools. Omnisend

My quick ranking

Bottom line: If you're on Shopify, WooCommerce, or BigCommerce, I'd start with Omnisend. You get the three things you specifically asked for—coupons + abandoned carts + segmentation—inside one ecommerce-focused system, without immediately needing Zapier or other paid connectors.

One caveat: watch the billable-contact rules as you grow. Omnisend can count some non-subscribed customers who trigger automated messages, including abandoned-cart users, toward billing. Omnisend Help Center Omnisend Help Center

If you tell me which store platform you use (Shopify, WooCommerce, Etsy, Squarespace, etc.) and roughly how many customers/emails you have, I can tell you which plan is likely cheapest.

For a small online store, I’d prioritize native ecommerce features over a general newsletter tool.

www.sequenzy.comwww.stackfyi.comwww.emailtooltester.com

My picks by store size

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

• Best value: MailerLite
• Best ecommerce automation: Omnisend www.sequenzy.comwww.stackfyi.comwww.emailtooltester.com

If you sell on Shopify and want the least setup:

• I’d lean toward Omnisend because the workflows you need (welcome series, abandoned cart, post-purchase, discount incentives, customer segments) are designed for ecommerce rather than bolted on. www.sequenzy.comwww.stackfyi.comwww.emailtooltester.com

If you’re trying to spend as little as possible:

• Start with MailerLite or Brevo, then move to Klaviyo later if you need deeper segmentation. www.sequenzy.comwww.stackfyi.comwww.emailtooltester.com

A simple setup I’d build for a small store:

1. Welcome email → introduce brand + first-purchase discount
2. Abandoned cart flow → reminder → social proof → optional discount
3. Post-purchase flow → thank you → review request → repeat purchase offer
4. Segments:
   • first-time buyers
   • repeat customers
   • high spenders
   • inactive customers (60–90 days)

Also, avoid giving a discount in the first abandoned-cart email by default; many stores use a reminder first, then an incentive later to protect margins. www.shopify.com

If you tell me your platform (Shopify, WooCommerce, Etsy, Squarespace, etc.) and approximate list size, I can narrow this to the cheapest option that won’t force you into paid integrations.

For a small online store, Omnisend is probably the best fit if you want those ecommerce features without paying for a pile of integrations.

Why I'd pick Omnisend: it is specifically built around ecommerce. Its workflows include cart abandonment, and segmentation can use shopping history, engagement, profile data, and customer lifecycle stage. It also supports store-linked discount codes. www.omnisend.com

The current free tier is 500 emails/month to 250 contacts. The Standard plan starts at $16/month normally, with a current new-subscriber introductory discount of 30% for the first three months when paying three months upfront. www.omnisend.comsupport.omnisend.com

One caveat: Omnisend's pricing counts billable contacts, including some non-subscribers who trigger things like abandoned-cart automation, so watch your contact count as the store grows. support.omnisend.com

Bottom line: If you're on Shopify, WooCommerce, BigCommerce, or a similar platform and want discounts + abandoned carts + meaningful customer segmentation in one place, I'd start with Omnisend rather than trying to assemble MailerLite/Brevo + separate ecommerce integrations.

Omnisend pricing 

For a small online store, I’d pick Omnisend first—especially if you’re on Shopify or another mainstream ecommerce platform.

Best fit: Omnisend

Omnisend

It hits your three requirements without needing a pile of add-ons:

• Abandoned-cart + abandoned-checkout automation built in. support.omnisend.com
• Discount-code blocks built into the email editor, so promotions don't require a separate integration. www.omnisend.com
• Dynamic segmentation based on customer behavior and purchase history. www.omnisend.com
• Native ecommerce/store syncing and prebuilt automation workflows. www.omnisend.com
• Current comparisons put its paid entry point around $16/month, with pricing generally below Klaviyo at comparable list sizes. kaspianfuad.com

How I'd compare the main options

If you're already on Shopify, I'd actually consider starting with Shopify's own email tools if your needs are fairly simple. Shopify currently provides abandoned-checkout automation, including customizable timing and discounts, without requiring a third-party email platform. www.shopify.com

Bottom line:

• Want the best combination of affordability + ecommerce automation: Omnisend
• Want the absolute simplest/cheapest setup on Shopify: Shopify Email/Messaging
• Expect complex customer segments and advanced personalization as you grow: Klaviyo

If you tell me what platform your store uses (Shopify, WooCommerce, Wix, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest option for your actual situation.

For a small ecommerce store, I’d pick Omnisend first.

Why it fits your requirements especially well:

Omnisend's free plan currently includes its full feature set, although it's limited to 250 contacts and 500 emails/month. Its Standard plan starts at $16/month. support.omnisend.comwww.omnisend.comhelp.brevo.com

The big advantage is that these features are native to the platform, rather than requiring you to stitch together a basic email service + automation tool + coupon system. Its segmentation can use things such as purchases, engagement, and abandoned carts, and its ecommerce features include discount-code blocks and prebuilt abandoned-cart workflows. www.omnisend.com

How I'd rank the budget options

1. Omnisend — best overall for your requirements. Especially good if you're on Shopify or another mainstream ecommerce platform.
2. Brevo — cheapest alternative worth considering. It supports abandoned-cart sequences and coupon codes, but unique coupon codes require an API or compatible plugin, so it can involve more setup. help.brevo.com
3. Shopify Email — cheapest if you're already on Shopify. It can be extremely economical, but Omnisend is the better choice if segmentation and automated revenue recovery are priorities. Shopify Email has a free allowance of up to 10,000 emails/month. www.omnisend.com
4. MailerLite — good general-purpose budget emailer, but I'd choose it over Omnisend only if your ecommerce automation needs are relatively simple. Current comparisons put it around $15/month at 1,000 contacts versus Omnisend around $20 at that list size. www.omnisend.com

Bottom line: If your goal is “I want abandoned carts, discount codes, and useful customer segments without paying for a bunch of integrations,” Omnisend is probably the sweet spot. Start free, build your abandoned-cart + welcome + post-purchase flows, and upgrade only when your list grows.

If you tell me what platform your store runs on (Shopify, WooCommerce, Wix, etc.) and roughly how many subscribers you have, I can narrow this down to the cheapest option for your exact setup.

For a small ecommerce store, I’d choose Omnisend.

Why it fits your requirements particularly well:

• Abandoned-cart emails: built-in workflows for abandoned carts and abandoned checkouts, so you don't need a separate automation app. support.omnisend.com
• Discount codes: ecommerce-focused features include store-linked discount codes. www.omnisend.comwww.omnisend.com
• Segmentation: supports behavioral and purchase-history segmentation, including prebuilt segments. www.omnisend.comwww.omnisend.com
• Low starting cost: its Standard plan currently starts at $16/month, while the free plan includes core campaigns, automations, forms, and segmentation, with up to 500 emails/month and 250 contacts for sending. support.omnisend.com
• Less integration hassle: it's designed specifically around ecommerce workflows rather than requiring you to bolt together several marketing tools.

How I'd compare the main choices

MailerLite is cheaper at some list sizes—for example, its Growing Business plan is listed at $15/month for 1,000 subscribers—but Omnisend is substantially more ecommerce-oriented, particularly for discount codes, cart recovery, and purchase-based segmentation. www.omnisend.comwww.omnisend.com

Bottom line: If your priority is “I want abandoned carts + discount promotions + customer segments without paying for a pile of integrations,” choose Omnisend. Klaviyo is more powerful, but I'd wait until your store is large/complex enough to justify that extra sophistication.

For a small online store, Omnisend would be my first choice. It’s built specifically for ecommerce, so you can get the key pieces you mentioned without stitching together several apps or paying for Zapier-style integrations.

Why Omnisend stands out: its automation is available across its plans, including ecommerce workflows such as abandoned-cart recovery, and it has native integrations with platforms such as Shopify, WooCommerce, BigCommerce and Wix. Its paid plans start around $16/month, according to current 2026 comparisons. www.omnisend.comwww.omnisend.comwww.omnisend.com

For a small store, I'd set up:

1. Welcome series → introductory discount code.
2. Abandoned cart → reminder → second email with an incentive.
3. Post-purchase → thank-you → cross-sell/repeat-purchase offer.
4. Segments → first-time buyers, repeat customers, high-value customers, and people who haven't purchased recently.
5. Win-back → targeted discount for lapsed customers.

When I'd choose something else

• Klaviyo if sophisticated behavioral segmentation is your top priority and you're willing to pay more. It's particularly strong once your customer data and automation become complex. www.omnisend.com
• Mailchimp if you're primarily sending newsletters and only need relatively basic ecommerce automation. Its more advanced ecommerce workflows require higher tiers, which reduces its appeal for a store centered on abandoned carts and customer journeys. www.omnisend.comwww.omnisend.comwww.omnisend.com
• Brevo if your absolute priority is minimizing the monthly email bill and your ecommerce requirements are relatively simple.

Bottom line: start with Omnisend. For a small ecommerce operation wanting discounts + abandoned carts + segmentation + minimal integration hassle, it hits the sweet spot better than paying Klaviyo prices for capabilities you may not yet need. www.omnisend.comwww.omnisend.comwww.omnisend.com

If you tell me whether your store is Shopify, WooCommerce, Etsy, Squarespace, or something else and roughly how many subscribers you have, I can narrow it down to the cheapest suitable option.

For a small ecommerce store, I’d shortlist these:

My pick: Omnisend

If your priorities are discount-driven campaigns + abandoned carts + useful segmentation without paying for a bunch of connectors, Omnisend is probably the sweet spot.

It is built specifically for ecommerce and says its major ecommerce integrations work out of the box without third-party connectors or extra setup. Its segmentation can use real-time behavioral and purchase data. www.omnisend.com

Its 2026 pricing comparison puts it around $20/month for 1,000 contacts, $81 for 5,000, and $132 for 10,000, though pricing can change and depends on the plan/features you choose. www.omnisend.comwww.omnisend.comhelp.shopify.com

But if you're already on Shopify...

Shopify Messaging may actually be the cheapest answer. Shopify currently offers built-in automations for abandoned cart, abandoned checkout, browse abandonment, welcome emails with discounts, and discount-based welcome sequences. help.shopify.com

It can also put a discount directly into an abandoned-checkout recovery email. help.shopify.com

Shopify reports up to 10,000 emails/month free with Shopify Messaging in its current pricing comparison, making it particularly attractive for a very small list. www.omnisend.comwww.omnisend.comhelp.shopify.com

Bottom line:

• Shopify + tiny budget: Shopify Messaging
• Shopify/WooCommerce + want more sophisticated segmentation and automation: Omnisend
• Large/complex store where segmentation is worth paying for: Klaviyo
• Mostly newsletters rather than ecommerce automation: MailerLite

If you tell me your store platform (Shopify, WooCommerce, Squarespace, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest option that covers all three requirements.

For a small ecommerce store, Omnisend is probably the best fit for what you described.

Why Omnisend

• Abandoned-cart emails: built in, with ecommerce-specific automation rather than requiring Zapier or another connector.
• Discount codes: can connect discounts to your store and use them in automated campaigns.
• Segmentation: supports behavioral and purchase-history segments, so you can target things like first-time buyers, repeat customers, or people who haven't purchased recently. www.omnisend.com
• Ecommerce integrations: native integrations with platforms such as Shopify, WooCommerce, BigCommerce, and Wix, which reduces the need for costly third-party integrations. www.omnisend.comwww.omnisend.com
• Price: current 2026 pricing starts around $16/month for paid plans, with a free tier available. www.omnisend.comwww.omnisend.com

My ranking for your particular requirements:

MailerLite is cheaper, but its ecommerce segmentation is less sophisticated. Klaviyo is more powerful, but you're likely paying for capabilities you don't need yet. Omnisend sits in the sweet spot: ecommerce-native automation without Klaviyo-level pricing. www.omnisend.com

If you're on Shopify, I'd lean even more strongly toward Omnisend because you can keep the cart, customer, order, product, discount, and segmentation data in the same ecosystem instead of stitching together several apps. www.omnisend.comwww.omnisend.com

Bottom line: start with Omnisend. For a small store focused on recovering carts and sending targeted discount offers, it's likely the best price-to-feature combination.

For a small ecommerce store, Omnisend is probably the best fit for what you described.

Omnisend's prebuilt ecommerce workflows include abandoned-cart automation, and its segmentation can target customers by purchase history, engagement, products purchased, discount codes used, and more. www.omnisend.com

The discount-code feature is particularly useful: for Shopify, BigCommerce, and WooCommerce, Omnisend can generate unique codes automatically and sync them with your store, so you don't need a separate coupon/integration system. www.omnisend.com

My recommendation

Start with Omnisend Free if you're under 250 contacts. Once you outgrow it, the Standard plan is a relatively inexpensive step up. The main catch is that Omnisend's billing can include non-subscribers who abandon carts, so your billable contact count can be higher than your marketing-subscriber count. support.omnisend.com

MailerLite is another inexpensive option and has strong segmentation, but for a store where abandoned carts + coupons + ecommerce automation are central, I'd pick Omnisend because those capabilities are more directly built around ecommerce. www.mailerlite.com

If you tell me whether you're on Shopify, WooCommerce, Etsy, Squarespace, or something else, I can narrow it down to the cheapest 2–3 options for your exact store.

For a small online store, Omnisend is probably the best fit for your requirements.

\*Starting prices can change with list size and plan.

Why I'd pick Omnisend

It is built specifically around ecommerce rather than being a general newsletter platform. It supports abandoned-cart workflows, purchase-based segmentation, product recommendations, and discount codes without requiring you to stitch together several separate services. Its discount feature can automatically generate unique, trackable codes for Shopify and BigCommerce. www.omnisend.com

The current Standard plan starts at $16/month, and Omnisend has a free tier with its standard features, although the free plan is limited to 250 contacts and 500 emails/month. support.omnisend.com

One important caveat: Omnisend's pricing counts non-subscribers who enter abandoned-cart/behavioral automations as billable contacts, so your effective cost can rise faster than your newsletter subscriber count suggests. support.omnisend.com

My recommendation: If you're on Shopify, WooCommerce, or BigCommerce and your priority is “I want abandoned carts + coupons + useful customer segments without paying for a bunch of integrations,” start with Omnisend. If you're extremely price-sensitive and mostly need newsletters rather than sophisticated ecommerce automation, MailerLite is worth considering instead. www.omnisend.com

If you tell me your ecommerce platform (Shopify, WooCommerce, Etsy, etc.) and roughly how many subscribers you have, I can narrow it down to the cheapest option for your specific store.

If you’re a small ecommerce store, I’d shortlist these:

🥇 My pick: Omnisend

For your requirements, Omnisend is probably the sweet spot. It is designed specifically for ecommerce rather than being a generic newsletter platform, with abandoned-cart workflows, customer segmentation, and promotional/discount functionality built in. Current comparisons put it around $20/month for 1,000 contacts and $81/month for 5,000, though pricing can change. www.omnisend.com

The big advantage is that you don't need to stitch together a separate cart-recovery app + email platform + segmentation tool. That's where supposedly "cheap" solutions can become expensive.

🥈 If you're on Shopify and really want to minimize spending

Shopify Messaging deserves a serious look. It's reported as free for up to 10,000 emails/month, and Shopify has built-in customer segments and the ability to target discounts to specific segments. www.omnisend.com

I'd choose this if your needs are fairly straightforward and you don't need sophisticated multi-step automation.

🥉 Mailchimp

Mailchimp is attractive if you want to start cheaply: its Shopify app has a free plan and supports abandoned-cart emails, unique discount codes, and Shopify-based customer segmentation. apps.shopify.comapps.shopify.com

However, for an ecommerce-first business, I'd lean toward Omnisend over Mailchimp because the former is more purpose-built around ecommerce automation.

Bottom line:

• Shopify + very small list → Shopify Messaging
• Small ecommerce store wanting the best combination of automation + price → Omnisend
• Want a familiar, general-purpose platform with a free starting option → Mailchimp
• Need sophisticated segmentation/automation and can spend more → Drip (currently $39/month starting price). apps.shopify.com

If you tell me Shopify/WooCommerce/etc. + roughly how many subscribers you have, I can narrow it down to the cheapest option for your actual store size.
