Founded in 2005 by childhood friends, Paul Farnell, Matthew Brindley, and David Smalley, Litmus began as a cross-browser testing tool. Shortly thereafter, they recognized another need in the design and marketing field—email testing. And email has been its focus ever since.

Over time, Litmus expanded its platform to include email creation, testing, and analytics tools, empowering marketers, designers, and agencies to deliver superior subscriber experiences. Today, Litmus helps more than 250,000 marketers make email better. It’s been an amazing journey, and Litmus looks forward to continuing to help you create more possibilities with email.
