Best Email Marketing for E-commerce in 2025
E-commerce email is different from general email marketing. Here's which platforms are worth using for online stores and which ones to avoid.
Why e-commerce email is different
General email marketing tools let you send newsletters and basic campaigns. E-commerce email marketing tools let you trigger personalised messages based on what customers buy, browse, and do — and show you exactly how much revenue each email generates.
The difference is data integration. Klaviyo, Omnisend, and Drip connect directly to your store and pull in real-time purchase and browse data. Mailchimp has e-commerce integrations, but they're less deep, and the attribution is less accurate.
Klaviyo — The standard for serious stores
Used by Glossier, ColourPop, and tens of thousands of Shopify and WooCommerce stores, Klaviyo is the industry benchmark for e-commerce email marketing. Its edge is data depth: predicted lifetime value, churn probability, product affinity, and purchase frequency segmentation enable personalisation that general platforms can't replicate.
The pre-built flows are the fastest path to revenue. Welcome series, abandoned cart, browse abandonment, post-purchase, and win-back sequences can be live in an afternoon and will generate revenue from day one.
Klaviyo gets expensive as you scale — the pricing jumps significantly at higher contact counts. But the revenue attribution shows you clearly what each segment generates, which makes the ROI calculation straightforward.
Best for: Shopify stores doing $20k+/month in revenue that want to maximise email as a channel.
Omnisend — Best value e-commerce automation
Omnisend offers email, SMS, and push notifications in one platform at lower cost than Klaviyo, with native Shopify and WooCommerce integrations and pre-built automation workflows. For stores just starting to invest seriously in email automation, Omnisend is the most practical starting point.
The free plan (250 contacts) is genuinely useful. The automation quality is good without being as sophisticated as Klaviyo.
Best for: Small to mid-size e-commerce stores wanting email and SMS together without Klaviyo's pricing.
Drip — Best for DTC brand storytelling
Drip was built specifically for DTC brands and covers email and SMS with behaviour-triggered campaigns. It's particularly strong for brands that invest in the relationship side of e-commerce — post-purchase education sequences, product anniversary campaigns, loyalty programmes — rather than just promotional blasts.
Best for: DTC brands focused on customer relationships and lifetime value rather than one-time transactions.
When Mailchimp is fine
For stores with simple email needs — a weekly newsletter and occasional promotions — Mailchimp's Shopify integration is adequate. The automation is basic and the revenue attribution is less precise than dedicated e-commerce tools, but if you're just starting out and your email strategy is still developing, Mailchimp is a reasonable starting point before investing in Klaviyo.
The clear sign you've outgrown Mailchimp: you want to send different emails to customers based on what they bought, browsed, or haven't done recently. That's when a dedicated e-commerce platform pays for itself.
