Protect your brand reputation with every email send

Email clients update every 2 days. And that means more chances for display errors (and less conversions). How can you keep up? Litmus helps you get more out of your emails with the power to test and preview in 90+ email clients—including Dark Mode—in one spot. In seconds.

“Litmus allows us to catch errors more easily and helps us be more aware of how our emails look to our subscribers—insights we did not have before.”


Sean Kennedy, Product Marketer at Zapier
