So I was working on an html email that works across all emails, and everything works with the exception of one thing: The background color doesn't show up in yahoo mail (tested in chrome). Optimally, the linear gradient would work in yahoo mail, but that isn't showing up. I know for HTML emails the format should be a table, but the format is working in this instance. I also know that everything should be inline, I just put the code in putmail to move everything inline. Attached is a link to the full HTML/CSS code. If you guys could let me know why yahoo isn't displaying the background color or linear gradient, that would be great. Thanks :)
