Litmus - 2026 Pricing, Features, Reviews & Alternatives

Litmus in an email development tool for marketing teams. Litmus allows marketers from companies of all sizes to build, preview, test and track their email campaigns. With Litmus, teams can resell, markup & add value to all of their client engagements.

Litmus's web-based drag & drop email editor enables teams to build their own emails from scratch or select one from Litmus's gallery of fully customizable templates. Changes made to emails can't be lost thanks to Litmus's timeline view. Contributors can see who made changes and when, and restore previous versions at any time.

Users can preview emails simultaneously in mobile and desktop as they build them, ensuring that they're optimized for both dimensions. HTML changes can be applied and viewed immediately and in real-time, eliminating the need for "guessing and checking".

After building and previewing emails, users can send them to Litmus for rendering testing with Litmus's one-click email testing. Litmus's comprehensive spam testing then checks your authentication, IP addresses & reputation and provides feedback and scores for ISP and corporate filters to ensure that your emails reach inboxes.

Once emails are sent, Litmus's engagement summary reports to users on not just open rate, but whether the emails were deleted, glanced at, skimmed over or properly read. Geolocation tells users where emails were opened, too.
