Just like how you wouldn't want to get on stage without your pants on (how embarrassing), Litmus makes sure that your emails look great before they are on stage in your subscribers' inbox.

Catch errors before you hit the send button

Ensure your email follows key accessibility best practices

Looks aren’t everything. Hear how your email sounds on a screen reader and check if your HTML is optimized for subscribers with visual or cognitive impairments—and create emails that are accessible to everyone.
