I just want to wrap notifications sent by WHMCS in a boxed, responsive, email template. Basically just one block of content, with a header and a footer. Wanted a boxed template that would look decent on Gmail App / Outlook.
I tried sending samples from some templates around here but they all looked awful in Gmail App. And I don’t wanna buy the ones that i can’t send a sample just to see if it’s compatible, because the chances are very low 
Any suggestions? I’m starting to feel depressed about this
