Yahoo! Mail Beta

STATUS: Solid Support screenshot

Summary: Yahoo! Mail is a model webmail client, supporting nearly everything on our list and a whole lot more. We can only hope that other webmail-client developers will learn from the support Yahoo! Mail offers without compromising security, speed or features.

Note that when inline styles have been applied to the body tag, these styles can be moved by Yahoo! Mail Beta and affect the entire email newsletter in unexpected ways. In our screenshot, text-align: center and width: 100% has ended up unintentionally being applied to all content, not just the container. Last updated: 09 July 2011
