Don’t know if any of my followers do any work in email marketing/promotions, but I find this tool ridiculously useful so figured I’d pass it along to anyone who might find it similarly useful. Premailer a free-to-use preflight tool for HTML email that automatically formats an HTML page into the best format for cross-compatability across different email platforms. Basically, making sure your email looks the way you want it to in as many places as possible. I usually store my HTML emails online, but you can just paste the code in, too.
Sorry if this was boring.
