Email marketing generates $36 for every $1 spent, making it the highest-ROI marketing channel for e-commerce. Yet most WooCommerce store owners either use no email marketing or have a Mailchimp account they set up once and forgot about.
The gap between "has email" and "uses email well" is where revenue lives. A proper email setup — abandoned cart recovery, post-purchase sequences, restock reminders, win-back campaigns — can add 20-30% to your store's revenue with relatively little ongoing effort once configured.
Here's an honest comparison of the email marketing plugins that work best with WooCommerce.
What E-Commerce Email Marketing Requires
Generic email marketing (newsletters, broadcasts) is one thing. E-commerce email marketing needs more:
- WooCommerce data sync. Products, orders, customer purchase history available in the email platform.
- Behavioral triggers. Abandoned cart, post-purchase, browse abandonment, restock reminders.
- Segmentation based on purchase data. "Customers who bought product X but not Y" or "customers who haven't ordered in 60 days."
- Product recommendations. Dynamic product blocks in emails based on purchase history.
- Revenue attribution. Know exactly how much revenue each email campaign generates.
Not every email plugin does all of these well. Let's see who does what.
Klaviyo: Best for Serious E-Commerce Stores
Price: Free up to 250 contacts. Paid from $20/month (251-500 contacts). Scales steeply — $100/month at 5,000 contacts, $350/month at 15,000.
Strengths
Deep WooCommerce integration. Klaviyo syncs your entire WooCommerce database — products, orders, customer profiles, browsing behavior. This data powers everything else.
Pre-built automation flows. Welcome series, abandoned cart, post-purchase, win-back, browse abandonment — all come as templates you can customize. A new store can have a complete email automation system running in an afternoon.
Segmentation power. This is Klaviyo's real strength. Build segments like:
- "Bought supplements in last 90 days but not in last 30 days" (restock reminder candidates)
- "AOV over $100 and 3+ orders" (VIP customers)
- "Opened last 3 emails but didn't purchase" (engaged non-buyers)
Revenue attribution. Every email, flow, and campaign shows attributed revenue. You know exactly which emails make money.
SMS integration. Add SMS to your email flows. Useful for abandoned cart recovery and flash sales.
Weaknesses
Price. Klaviyo gets expensive fast. At 10,000 contacts, you're paying $175/month. At 25,000, over $400/month. For small stores, this is a significant cost.
Complexity. The power comes with complexity. The interface has a learning curve. Budget 4-8 hours for initial setup and learning.
Template design. Email templates are functional but not the most beautiful. Design customization requires some HTML/CSS knowledge.
Best For
Stores doing $10K+/month that want to maximize email revenue. Subscription stores. Stores with replenishable products.
Verdict: If email is going to be a primary revenue channel (and for e-commerce, it should be), Klaviyo is the best platform. The cost is justified by the revenue it generates — but only if you actually use the automation and segmentation features.
Mailchimp: The Name Everyone Knows
Price: Free up to 500 contacts (limited). Essentials from $13/month. Standard from $20/month. Premium from $350/month.
Strengths
Brand recognition. Customers trust Mailchimp emails more than unknown senders. The brand adds legitimacy.
Email design. Mailchimp's email builder is the most intuitive of any platform. Beautiful templates, easy drag-and-drop, good mobile preview.
Content creation tools. AI writing assistant, design tools, landing pages, social posting — Mailchimp is becoming an all-in-one marketing platform.
Affordable entry point. The Essentials plan at $13/month for 500 contacts is reasonable.
Weaknesses
Weak WooCommerce integration. This is Mailchimp's biggest problem for e-commerce. The official integration is basic — it syncs customers and basic order data, but advanced segmentation and automation triggers are limited compared to Klaviyo.
Limited e-commerce automation. Abandoned cart emails exist but are basic. No browse abandonment in the lower plans. Post-purchase flows are simple.
Pricing surprises. Mailchimp counts unsubscribed contacts toward your limit. Archive contacts aggressively or you'll pay for people who can't receive your emails.
Revenue attribution. Less detailed than Klaviyo. Harder to know exactly how much money each campaign generates.
Best For
Small stores that need basic email marketing and newsletters. Stores where email is one channel among many, not the primary revenue driver.
Verdict: Mailchimp is good at email marketing. It's mediocre at e-commerce email marketing. If your store relies heavily on email for repeat revenue, you'll outgrow Mailchimp quickly.
MailPoet: Best WordPress-Native Option
Price: Free up to 1,000 subscribers (MailPoet sending). Premium from $13/month.
Strengths
Lives inside WordPress. No external platform, no separate login. Everything happens in your WordPress admin. For store owners who spend their day in WP, this is genuinely convenient.
WooCommerce integration (built-in). MailPoet was acquired by WooCommerce's parent company (Automattic). The integration is deep and native — purchase-based segments, order triggers, product blocks in emails.
Simple automation. Welcome emails, first-purchase follow-up, abandoned cart. Not as powerful as Klaviyo but covers the essentials.
Affordable. Free for up to 1,000 subscribers with their sending service. Premium is reasonable.
Weaknesses
Limited advanced features. No browse abandonment. Limited segmentation compared to Klaviyo. Basic reporting.
Template variety. Fewer templates and less design flexibility than Mailchimp.
Scale limitations. For stores with 10,000+ contacts, MailPoet can slow down your WordPress admin.
Best For
Small WooCommerce stores that want simple, affordable email marketing without leaving WordPress.
Verdict: The best starting point for stores that are new to email marketing. You'll eventually outgrow it, but it handles the basics well and the WooCommerce integration is excellent.
Omnisend: E-Commerce Focus at Mid-Range Pricing
Price: Free up to 250 contacts. Standard from $16/month. Pro from $59/month.
Strengths
Built for e-commerce. Unlike Mailchimp (which serves all businesses), Omnisend is specifically designed for online stores. Every feature is e-commerce-oriented.
Multi-channel. Email + SMS + push notifications in one platform. Useful for abandoned cart recovery across channels.
Pre-built automations. Similar to Klaviyo's flow templates but with a simpler interface. Abandoned cart, welcome, post-purchase, browse abandonment all included.
Product picker. Pull products directly from your WooCommerce catalog into emails. Automatic pricing, images, and buy links.
Good WooCommerce integration. Syncs products, orders, and customer data effectively.
Weaknesses
Less powerful segmentation. Not as granular as Klaviyo. Advanced behavioral segments require the Pro plan.
Smaller ecosystem. Fewer integrations with other tools compared to Klaviyo or Mailchimp.
Deliverability. Some users report lower deliverability rates compared to Klaviyo and Mailchimp, though Omnisend has been improving this.
Best For
Mid-sized stores that want Klaviyo-like features at a lower price point. Stores that want email + SMS in one platform.
Verdict: The best middle ground between Mailchimp's simplicity and Klaviyo's power. Good value for stores in the $5K-$30K/month range.
AutomateWoo: WordPress-Native Automation
Price: $9.92/month (billed annually at $119)
Strengths
Deep WooCommerce integration. Made specifically for WooCommerce. Triggers based on any WooCommerce event — order status changes, product reviews, subscription events, customer actions.
WordPress-native. Runs inside WordPress, not an external SaaS. Your data stays on your server.
Flexible automation. Build custom workflows with triggers, rules, and actions. More flexible than most SaaS platforms for custom automations.
One-time/annual cost. No per-contact pricing. Whether you have 500 or 50,000 contacts, the price is the same.
Pairs with any email sender. AutomateWoo handles the automation logic; you can use any SMTP service (Amazon SES, Postmark, SendGrid) for actual email delivery. This keeps sending costs low.
Weaknesses
Not an email platform. It's an automation engine, not a full email marketing platform. You need a separate solution for email templates, campaign broadcasts, and contact management.
Technical setup. Requires more configuration than SaaS platforms. Not for beginners.
No built-in analytics. Revenue attribution and campaign analytics are basic.
Best For
Technical store owners who want maximum automation flexibility at a flat cost. Stores that already have an email delivery setup and need WooCommerce-specific automation.
Verdict: A powerful automation tool, but not a complete email marketing solution. Best used alongside a simpler email platform for broadcasts.

Essential Automations Every Store Needs
Regardless of which plugin you choose, set up these five automations first:
1. Welcome Series (3-5 emails)
- Email 1 (immediate): Welcome + discount code
- Email 2 (day 2): Brand story + best sellers
- Email 3 (day 5): Social proof + customer reviews
- Email 4 (day 7): Discount reminder (if unused)
2. Abandoned Cart Recovery (3 emails)
- Email 1 (1 hour): "You left items in your cart" + cart contents
- Email 2 (24 hours): Social proof + urgency
- Email 3 (72 hours): Small discount to close
3. Post-Purchase Follow-Up (2-3 emails)
- Email 1 (day 3): Delivery check-in + usage tips
- Email 2 (day 14): Review request
- Email 3 (day 30): Cross-sell related products
4. Win-Back Campaign
- Trigger: No purchase in 60-90 days
- Offer: Exclusive discount or new product preview
5. Restock Reminder
- Trigger: X days after purchase of consumable product
- Content: "Time to reorder?" with one-click reorder
These five automations, once set up, run forever and generate revenue on autopilot. They're the foundation of e-commerce email marketing.

Common Email Marketing Mistakes
Only sending newsletters. Broadcasts are the least effective email type. Automated, triggered emails based on behavior outperform newsletters by 3-5x.
Sending too often (or not enough). For most stores, 1-2 broadcasts per week plus automated flows is the sweet spot. More than daily kills engagement. Less than weekly wastes the channel.
Ignoring deliverability. Sending to inactive contacts hurts your sender reputation, which hurts deliverability to everyone. Clean your list quarterly — remove contacts who haven't opened in 6+ months.
No segmentation. Sending the same email to everyone is lazy and wasteful. At minimum, segment by purchase history (buyers vs. non-buyers) and engagement (active vs. inactive).
Skipping abandoned cart emails. This is literally free money. 5-15% of abandoned carts convert via email recovery. If you do nothing else, do this.
The Bottom Line
Email marketing is the highest-ROI channel for e-commerce stores. The plugin you choose matters less than whether you actually set up and use automations.
Start with MailPoet if you're new. Graduate to Omnisend as you grow. Move to Klaviyo when email becomes a primary revenue channel. The important thing is to start — even basic abandoned cart emails will pay for whatever plugin you choose within the first month.
List AI helps WooCommerce stores build bigger carts with AI-powered cart filling. Bigger initial carts mean higher-value customers entering your email automation flows — which means more revenue from every sequence you build.
