Best Email Marketing for Ecommerce and Shopify (2026): Klaviyo vs Omnisend vs Shopify Messaging

Omnisend is built for online stores and prices its plans openly. Standard starts at $16 a month for up to 500 contacts and lets you send 12 emails per contact per month. Pro starts at $59 a month and adds unlimited email under a fair-use policy, SMS, personalized product recommendations, conditional content and personalized send times.

Its automations cover what most stores need: cart and browse abandonment, order and shipping confirmations, welcome series and win-back, with pre-built templates for each. Signup forms include exit-intent popups, prize-based sign-up forms and popup A/B testing. Support is 24/7 by chat and email on every plan.

Which plan to pick: Standard if email is your main channel. Pro if you send heavily, want SMS or want product recommendations inside automated emails. New paid customers can save 30% for the first 3 months by paying 3 months upfront.

Watch out for: billable contacts. Omnisend bills for subscribers and for non-subscribers who receive automated messages, such as shoppers who abandoned a cart without opting in. Unsubscribed contacts are not billed. Your price can rise even when your subscriber count does not, so check your billable contact count in Omnisend each month.

Klaviyo is the platform many larger online brands grow into. It connects to your store, builds a profile for every shopper and lets you segment and trigger flows on what they browse and buy. The free plan is a real working account: you can import or sync contacts, use the drag-and-drop editor, and build automations, segments and reports, within 250 active profiles and 500 emails a month.

Beyond email, Klaviyo sells separate products that share the same customer data, including a mobile messaging plan for text messages, reviews, a helpdesk, an AI customer agent and marketing analytics. Each is priced separately, so check Klaviyo’s pricing page for current rates.

Which plan to pick: start free to connect your store and build your flows. Move to a paid email plan sized to your active profile count when you pass 250 profiles or 500 emails a month.

Watch out for: profile growth. Klaviyo prices paid plans by active profiles, which it describes as contacts who can receive marketing emails, and the free plan stops sending once you pass 250 active profiles or 500 emails in a month. Suppress contacts you no longer market to, and check Klaviyo’s billing help pages for how and when your plan is adjusted.

Shopify Messaging is Shopify’s own email marketing app. You create, send and track campaigns inside the Shopify admin, with templates that pull in your products and branding, and Shopify’s Sidekick assistant can edit an email when you describe the change. Automations cover the essentials: abandoned cart and checkout, browse abandonment, welcome, follow-up and win-back emails.

Which plan to pick: there are no plans. You install it free, send up to 10,000 emails a month at no charge, then pay from $1 per 1,000 emails.

Watch out for: depth. It is the cheapest start in this guide for a Shopify store, but if you want advanced segmentation, per-product recommendations or a separate helpdesk and reviews tool, compare it with Omnisend or Klaviyo as the store grows.
