How We Evaluated
Ecommerce email marketing is different from regular email marketing. You need abandoned cart flows, post-purchase sequences, product recommendations, and segmentation based on what people bought, browsed, or added to their cart. A platform that's great for newsletters might be terrible for ecommerce automation. This list focuses on what each software platform offers for online stores specifically, not just whether it can send campaigns.
We evaluated each platform on four ecommerce-specific criteria: depth of store integration (product sync, purchase tracking, browsing data), pre-built ecommerce automations (abandoned cart, win-back, browse abandonment), revenue attribution (can you see which email generated which sale), and SMS capabilities (increasingly important for store communication). We tested fit across Shopify, WooCommerce, and BigCommerce, since the best email automation software for one store stack is not always the best for another.
1. Klaviyo
Top pickPower smarter digital relationships
Klaviyo was built for ecommerce and it shows in every feature. It syncs product catalogs, purchase history, and browsing behavior from Shopify, WooCommerce, and BigCommerce in real time. Predictive analytics (customer lifetime value, churn risk, expected next order date) are included on all plans, not locked behind premium tiers. The 80+ pre-built flows cover abandoned carts, post-purchase sequences, win-back campaigns, browse abandonment, back-in-stock alerts, and price drop notifications. SMS is built in on the Email + SMS plan. Revenue attribution is automatic: you can see exactly how much each flow and campaign generated. The free plan covers 250 active profiles.
Strengths
- Best-in-class e-commerce integrations with Shopify, WooCommerce, and BigCommerce
- Powerful predictive analytics including customer lifetime value and churn risk
- Advanced segmentation driven by real-time behavioral and purchase data
- 80+ pre-built automation flow templates for abandoned carts, win-back, and more
Weaknesses
- Pricing gets expensive quickly as active profiles grow (e.g. $150/mo at 10K profiles)
- Steep learning curve with technical jargon in segment builder
- No built-in landing page builder (requires third-party tools)
- No migration support or onboarding assistance on non-Enterprise plans
Verdict: Best overall for e-commerce. If you run an online store and can afford it, start here.
2. Mailchimp
The #1 AI-powered email marketing and automations platform
Mailchimp is the most accessible ecommerce email marketing software for small stores. It integrates with Shopify, WooCommerce, and BigCommerce with product recommendation blocks, abandoned cart emails, and purchase follow-up automations. The drag-and-drop editor makes it easy to create product-focused emails without design skills. The free plan covers 250 contacts with landing pages included, and Essentials starts at $13/mo. Where Mailchimp falls short for ecommerce: segmentation based on purchase data is less granular than Klaviyo's, there's no predictive analytics, no browse abandonment tracking, and automation is capped at 4 steps on Essentials.
Strengths
- Intuitive drag-and-drop editor requiring no technical skills
- Generous free plan with landing pages, forms, and CRM included
- 300+ integrations with popular e-commerce, CRM, and analytics tools
- Extensive template library with hundreds of mobile-responsive designs
Weaknesses
- Pricing escalates sharply as contact lists grow past 500
- Unsubscribed and inactive contacts still count toward billing limits
- SMS marketing requires a separate paid add-on starting at $20/mo
- Advanced automation limited to 4 journey steps on Essentials plan
Verdict: Best for small stores on a budget that need basic e-commerce email without Klaviyo's complexity or cost.
3. ActiveCampaign
Marketing automation for any business
ActiveCampaign is the pick for stores that also need a CRM or more flexible ecommerce email automation. It integrates with Shopify, WooCommerce, and BigCommerce with abandoned cart tracking and purchase-based automation. The automation builder (135+ triggers, unlimited steps) is more flexible than Mailchimp's and can handle complex multi-branch sequences. The built-in CRM with deal pipelines lets you track wholesale accounts or B2B orders alongside your ecommerce marketing. The trade-off: the ecommerce data sync isn't as deep as Klaviyo's. No real-time browsing data, no predictive CLV, and fewer pre-built ecommerce flows.
Strengths
- One of the most powerful automation builders available (135+ triggers, 500+ recipes)
- Built-in CRM with deal pipelines for marketing-sales alignment
- High email deliverability with built-in list hygiene and spam testing
- 900+ native integrations plus 8,000+ via Zapier
Weaknesses
- Costs scale aggressively with contact count (Pro jumps to $339/mo at 10K contacts)
- Significant learning curve requiring 3-4 training sessions for most users
- Key features like A/B testing and predictive content gated behind Pro tier
- Overkill for simple newsletters or basic email needs
Verdict: Best for stores that need e-commerce email plus a CRM for wholesale or B2B sales. Not as deep on store data as Klaviyo.
4. Constant Contact
Digital and email marketing platform for small business
Constant Contact works for very small stores with simple email needs. It integrates with Shopify and WooCommerce with basic product blocks and purchase-triggered emails. The editor is straightforward, deliverability is strong (88% in independent tests), and the 60-day free trial gives you more time to evaluate than any other platform. Where it falls short for e-commerce: no browse abandonment, no predictive analytics, automation is limited to 3 pre-built workflows on Standard, and A/B testing covers subject lines only. If your store needs anything beyond basic abandoned cart emails and newsletters, Constant Contact will hold you back.
Strengths
- High email deliverability rates (88% average in independent tests)
- Unique niche features like event ticketing, surveys, and registration
- Generous 60-day free trial with no credit card required
- 200+ responsive email templates with a straightforward editor
Weaknesses
- Poor price-to-performance ratio compared to modern competitors
- Limited automation capabilities lacking sophistication on lower tiers
- Account cancellation requires calling during business hours
- A/B testing restricted to subject lines only (no content testing)
Verdict: Adequate for very small stores with simple needs. Most growing stores will outgrow it quickly.

Klaviyo. It has the deepest Shopify integration of any email platform, with real-time product sync, predictive analytics, 80+ pre-built e-commerce flows, and built-in SMS. Mailchimp is a good budget alternative with a simpler Shopify integration.
Klaviyo is usually the best email automation choice for BigCommerce because it supports deeper product and purchase-data sync, stronger abandoned cart flows, and better post-purchase automation than the simpler alternatives. ActiveCampaign is the better fit if your BigCommerce store also needs a CRM or wholesale sales workflow.
If you sell products online and want to automate based on purchase data, browsing behavior, and cart activity, yes. General-purpose platforms like Mailchimp handle basic e-commerce email, but dedicated platforms like Klaviyo go much deeper on store data, predictive analytics, and pre-built flows.
Mailchimp starts at $13/mo for 500 contacts. Klaviyo starts at $20/mo for 500 active profiles. ActiveCampaign starts at $15/mo billed annually for 1,000 contacts. At 10,000 contacts, expect $100-150/mo depending on the platform. See our email marketing pricing comparison for detailed breakdowns.
For small stores with basic needs, yes. Mailchimp supports abandoned cart emails, product recommendations, and purchase follow-ups through its Shopify and WooCommerce integrations. It won't match Klaviyo on predictive analytics, browse abandonment, or real-time product sync, but it covers the basics at a lower price.
Most successful e-commerce brands use both. Email handles longer content (product launches, newsletters, educational content) while SMS drives urgency (flash sales, shipping updates, abandoned cart reminders). Klaviyo bundles both in a single platform. Mailchimp and ActiveCampaign treat SMS as a paid add-on.
Abandoned cart recovery. It targets shoppers who added items but didn't check out, and typically recovers 5-15% of abandoned carts. Every platform on this list supports it. After that, post-purchase follow-ups and win-back campaigns for inactive customers deliver the highest ROI.
