Omnisend vs Klaviyo (2026)

What sets it apart Combined email, SMS, and web push with ecommerce-specific automations

Best for Ecommerce store operators running email and SMS together · Pricing model Contact-based freemium: Free ($0, 250 contacts), Standard (from $11.20/mo, 500 contacts), Pro (from $41.30/mo, 2,500 contacts), plus volume-priced SMS add-ons; custom plan above 150,000 contacts

Omnisend is an email, SMS, and web push marketing platform built for ecommerce merchants, with integrations for Shopify, BigCommerce, WooCommerce, Wix, and similar storefronts. It combines campaign creation, pre-built automation workflows (welcome, abandoned cart, post-purchase), behavioral segmentation, and lead-capture forms and popups, with an Omnisend AI layer for content generation and audience insights. Billing counts subscribers plus non-subscribers who received automated messages, across a Free, Standard, and Pro tier structure. It fits store operators who want email and SMS managed together rather than through separate tools.

What sets it apart Deep native integration with ecommerce platforms feeds a customer-data layer that powers segmentation and behavior-triggered flows (abandoned-cart, browse-abandonment, back-in-stock), rather than treating email as a channel separate from store data

Best for Small and midsize direct-to-consumer ecommerce brands that want email and SMS automation driven by their store's own order and behavioral data (Shopify and similar platforms) · Pricing model Free tier: up to 250 active profiles, 500 email sends, and 150 SMS/mobile message credits per month. Paid plans scale by active-profile count; email plans start around $20/mo (per third-party coverage) and Email + SMS plans add roughly $15/mo per tier, with SMS billed through separate message credits. Klaviyo moved to active-profile-based billing in 2025.

A marketing automation platform built for ecommerce, Klaviyo pulls order, catalog, and behavioral data from a connected store and turns it into segments and automated message flows across email, SMS, WhatsApp, and mobile push. Its distinguishing trait is how closely it binds to store data: native integrations with Shopify and similar platforms feed a customer-data layer that triggers sequences such as abandoned-cart, browse-abandonment, and back-in-stock alerts. A free tier covers up to 250 active profiles and 500 monthly email sends, after which pricing scales by active-profile count, with SMS charged through separate message credits. The core users are small and midsize direct-to-consumer brands, though newer AI agents for campaign building and customer service extend it toward larger merchants.
