Litmus Inbox Preview In Mailchimp
Preview your emails as you build
Email clients update every 2 days on average, so it’s not enough to simply test at template creation. Preview and test emails in 100+ email clients and devices—including Dark Mode—as you build in Mailchimp’s editor.
Litmus Test + Chrome Extension
Catch costly errors before you send
Remember the last time you (or your boss) caught an error in your email… after you sent it? Analyze subject lines, verify links, preview your emails, and check your code for critical accessibility tags—before you send.
