We can’t say it enough: creating HTML emails is tricky. Even with loads of resources to help fix common issues, the bugs that cause rendering problems can be tough to crack.

Introducing Litmus Code Analysis

Code Analysis provides a compatibility report addressing client-specific CSS bugs in your email’s HTML. The report—based on Campaign Monitor’s legendary CSS support matrix and a few home-grown bonus rules—identifies incompatible CSS in your HTML and provides warnings along with their corresponding line numbers from your code.

As you click on each warning in the report, your HTML will automatically scroll to the location of the warning in your code.

Identify, fix and preview issues quickly and painlessly

Code Analysis is great for identifying problem areas so you can fix issues quickly and focus on more important things. Better yet, using Code Analysis in conjunction with Interactive Testing makes troubleshooting a breeze.

Code Analysis is automatically included on every new email test created in your account.
