Say goodbye to broken emails in less than 2 minutes.

An email preview shows how your email looks across different inboxes and devices like Gmail on iPhone or Outlook on desktop. It lets you check your email’s appearance before sending, so everything is just right. Each inbox or version you test counts as one preview; for example, checking six Outlook versions and three Apple Mail versions on both mobile and desktop would use 18 previews.

An email impression is how we count usage of personalized content like dynamic images or countdown timers. An impression is counted after the email is sent—every time someone opens and views your email. It helps you measure how many people actually see the dynamic content you send.

You don’t need an ESP to use Litmus, but Litmus can’t send emails for you. You’ll still need an ESP to deliver emails after you’ve tested, previewed, and improved your emails.

Think of Litmus as your trusty co-pilot: it checks your emails, ensures they look great everywhere, and tells you how they’re performing, while your ESP handles the actual delivery.

Litmus takes security seriously. That’s why we invest in the team, tools, and processes that keep your data safe, including completing a successful SOC 2 examination. Learn more about how we’re committed to keeping your data safe.
