Overview
Litmus
Litmus is an all-in-one email optimization platform designed to help you create flawless email experiences for every subscriber. You can build emails from scratch using a specialized code editor, or use visual tools to quickly assemble templates that work across all major platforms. The core strength lies in its automated testing, which lets you preview how your messages look in over 100 email clients and devices before you hit send.
Beyond just testing, you can use the platform to manage your entire email workflow, from collaborative reviews and approvals to advanced post-send analytics. It helps you identify broken links, missing alt text, and slow loading times that might hurt your engagement. Whether you are a solo marketer or part of a large enterprise team, the platform ensures your brand remains consistent and professional in every inbox.
