Litmus is an email marketing platform focused on the quality assurance and design phase of email campaigns. It allows users to preview how emails will look in 100+ different email clients and devices, which helps identify layout issues or broken links before the final send.
The tool is designed for marketers, designers, and developers who need a space to collaborate on email builds and approvals. It includes features for dynamic personalization and monitoring to support the subscriber experience.
Buyers should note that Litmus is not an email service provider (ESP); it does not send the emails itself but works alongside tools like Mailchimp or HubSpot. Those looking for a complete sending solution will still need a separate ESP to deliver their campaigns.
