Best email automation tools for ecommerce: which one should you pick?
Klaviyo is the default for ecommerce email automation because of its deep Shopify data sync and abandoned cart flows. Omnisend and Drip are strong cheaper alternatives; use Mailchimp only if you're already invested in it for other reasons, since its ecommerce automation is thinner.
Last updated 3 August 2026
| Tool | Best for | Price |
|---|---|---|
| Klaviyo | Shopify stores wanting the deepest data-driven automation | Free up to 250 contacts, paid from about $20 a month |
| Omnisend | Ecommerce stores wanting SMS and email bundled at lower cost | Free up to 250 contacts, paid from about $16 a month |
| Drip | Stores wanting visual workflow building with fewer contacts | From about $39 a month for up to 2,500 contacts |
| Mailchimp | Stores already using Mailchimp for general marketing email | Free up to 500 contacts, paid from about $13 a month |
| ActiveCampaign | Stores wanting automation plus a built-in CRM | From about $15 a month |
| Klaviyo SMS add-on | Adding SMS to an existing Klaviyo email setup | Billed per SMS credit, starting around $20 a month for a small volume |
Ecommerce email automation lives or dies on three flows: abandoned cart, post-purchase, and win-back for lapsed customers. A tool that does those three well, synced to real order data, will outperform a generic email platform with prettier templates but shallow ecommerce logic.
The differences below come down to how deeply each tool integrates with your store's product and order data, and how the pricing scales as your list and order volume grow — those two factors matter more than template design.
How we judged them
What matters when you're small.
Depth of store data sync
Look for real-time sync of product catalog, order history and browse behaviour, not just a one-way contact list import. This is what powers personalized product recommendations in emails.
Abandoned cart flow sophistication
A single reminder email is basic. Better tools support multi-step sequences with different timing and incentives based on cart value or product category.
Pricing model as orders grow
Some tools price by contacts, others by emails sent, and Klaviyo prices by contacts with SMS as a separate add-on. Model your cost at 2x your current list size before committing.
SMS and email in one platform
If you plan to run SMS alongside email, check whether it's a native feature with shared segments or a bolted-on add-on with separate reporting.
The picks
What each one is actually good at.
Klaviyo
Free up to 250 contacts, paid from about $20 a monthBest for: Shopify stores wanting the deepest data-driven automation
The strongest product-level data sync and pre-built flow templates for cart abandonment, browse abandonment and post-purchase upsells. Pricing rises quickly with list size, and SMS is billed separately.
Omnisend
Free up to 250 contacts, paid from about $16 a monthBest for: Ecommerce stores wanting SMS and email bundled at lower cost
Close to Klaviyo's flow depth at a noticeably lower price, with SMS credits included on paid plans. Reporting and third-party integrations are a step behind Klaviyo's ecosystem.
Drip
From about $39 a month for up to 2,500 contactsBest for: Stores wanting visual workflow building with fewer contacts
Clean visual automation builder and solid ecommerce triggers. No free tier and pricing per contact tier is less forgiving than Omnisend's at small list sizes.
Mailchimp
Free up to 500 contacts, paid from about $13 a monthBest for: Stores already using Mailchimp for general marketing email
Fine as a general email tool with basic ecommerce automation bolted on, but abandoned cart and product recommendation flows are shallower than the dedicated ecommerce tools. Don't switch to it for ecommerce specifically.
ActiveCampaign
From about $15 a monthBest for: Stores wanting automation plus a built-in CRM
Very capable automation builder with branching logic beyond most competitors, plus CRM features useful for stores with B2B or wholesale customers. Ecommerce-specific templates are fewer than Klaviyo's out of the box.
Klaviyo SMS add-on
Billed per SMS credit, starting around $20 a month for a small volumeBest for: Adding SMS to an existing Klaviyo email setup
Works well because it shares segments and flow logic with email, so a cart abandonment flow can branch across both channels. It's an add-on cost on top of your existing Klaviyo plan, not a standalone option.
Skip
What we'd leave alone.
- Generic email tools with no order or product data integration if abandoned cart recovery is your main goal — you'll be manually tagging carts, which defeats the purpose.
- Tools that charge full price for SMS credits you didn't ask for bundled into a plan — check whether SMS is optional before committing to a higher tier.
- Any platform requiring a long-term contract to unlock ecommerce-specific flow templates — month-to-month should be standard at this price point.
Questions
Common questions.
How much revenue does abandoned cart email actually recover?
It varies widely by store and average order value, so don't trust a fixed percentage claimed by a vendor. What's consistent is that a three-email sequence over 24-72 hours outperforms a single reminder email in most stores.
Should I start with SMS or focus on email first?
Start with email. It's cheaper to test and most ecommerce automation platforms let you add SMS later without rebuilding your flows from scratch.
Is Klaviyo worth the higher price over Omnisend?
If you're running complex, multi-branch flows with deep product recommendation logic, yes. For straightforward cart and post-purchase flows, Omnisend delivers close to the same result for less.
Do these tools replace a separate CRM?
Not fully. ActiveCampaign covers basic CRM needs, but if you have a wholesale or B2B sales process alongside your ecommerce store, you'll likely still want a dedicated CRM.
What's a realistic setup time for a first abandoned cart flow?
A basic three-email flow can be live within a few hours once the platform is connected to your store. Refining timing and copy based on performance data takes a few weeks of iteration.
