Litmus develops a cloud platform that enables marketers, designers, and agencies to build, preview, and optimize email campaigns. The service delivers instant email previews and quality-assurance tools that flag issues such as broken links or missing images before a message is sent. Its analytics suite then tracks performance so users can refine future outreach. More than 250,000 professionals rely on the product, underscoring meaningful market penetration. In October 2015, Litmus rolled out a major redesign incorporating instant previews and an interactive checklist feature. With fresh capital, the company plans to accelerate engineering and sales hiring, expand internationally, and launch new training and education initiatives. Although headquartered in Cambridge, MA, Litmus was originally founded in London by CEO Paul Farnell, CTO Matthew Brindley, and Managing Director David Smalley.
