It is wrapped in an html tag...

Please adopt decent HTML structure in the composer.

Just check the output of the composer and wrap it if needed. This is as simple as this...

I don't know, the developer needs to look at the code, needs to look at HTML in email spec if there is some and fix or implement the right format.
