HTML Email & “Bulletproof Background Images”

I have a guilty pleasure. Writing HTML email. 😅

I know it’s something I’m supposed to hate as a “Modern Developer”, but there’s something about writing in <tables> and debugging obscure alignment issues that brings me back to the earliest days of my career.

Anyway, I have a client that sends me these projects every so often, and a I recently received a design that relied heavily on background images. I was going to snap back a reply and insist that “background images aren’t supported in email clients” (something I’d been told, and have repeated often over the years), but then I decided to take a look around.

Turns out, either the techniques or documentation has evolved, and you can get pretty good support for background images in email!
