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

smbcompare.comwww.emailtooltester.comwww.shopify.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. The best affordable options that can handle discount codes + abandoned cart emails + segmentation without expensive Zapier/third-party integrations are: www.sequenzy.comwww.stackfyi.comwww.emailtooltester.com

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.

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.

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.
