Litmus provides an email marketing platform for creating, testing, reviewing, and analyzing email campaigns. Teams can build templates, preview how messages render across email clients, check accessibility and spam-related issues, collaborate on approvals, and measure performance. These tools help marketers improve quality assurance before sends and understand how campaigns behave afterward. Litmus is software used by email and marketing teams rather than a traditional agency, so its directory profile should focus on its campaign production and testing capabilities.
