Best Free Email Marketing Tools in 2026

Email, SMS, and push marketing for ecommerce

4.6/5 across G2 and Capterra · 2,080 ratings, Sep 2026

Omnisend is an ecommerce marketing automation platform that runs email, SMS, and web push notifications from one tool built specifically for online stores. Founded in 2014 and now used by more than 150,000 brands, it concentrates on the workflows that drive store revenue rather than general-purpose newsletters. It ships with 27 pre-built automation workflows for the moments that matter to merchants: welcome series, abandoned cart and browse-abandonment recovery, order and shipping notifications, and post-purchase win-back. A product picker drops catalog items straight into emails, and segmentation targets shoppers by purchase history, lifecycle stage, and engagement. Integrations are the main draw alongside price. Omnisend connects natively to Shopify, WooCommerce, BigCommerce, Wix, and Magento, plus around 160 other apps, syncing product, customer, and order data without custom development. It positions itself as a lower-cost alternative to Klaviyo while keeping the ecommerce-specific depth, with a free plan for up to 250 contacts and paid plans offering paid tiers. Omnisend suits ecommerce teams that want email and SMS in a single platform and value retail-ready automation over the breadth of a general marketing suite. It is a weaker fit for non-retail or B2B senders, where a general-purpose tool serves better.
