Fractal: HTML-CSS Validation For E-mails

E-mail code validation is a painful job considering many e-mail clients/applications have a low-level HTML-CSS rendering support and many others have their own standards. Actually, it is worse than designing for the browser.

Fractal is a free-to-use web application for validating HTML-CSS code across 24 most-popular e-mail clients.

It simply works by pasting the code to the application and finding out if each line is validated, if not, why and in which e-mail clients.


Best of all, Fractal doesn't come with only the bad news but also suggests fixes.

P.S. Besides the desktop and web-based e-mail applications, it also checks the code for the mobile as well.

    Thank you for writing about us! We hope this tool helps a lot of people out.

    We will soon be adding the ability to validate HTML via the W3C validator and also validating any links/images present in the HTML email, as an option.
