Many emails I receive from sites have HTML markup of some sort for their newsletters. I would like to be able to have this in my phpBB emails I send to my users. How can I do this? I tried editing admin_send_email.txt with HTML but that obviously wouldn't work. Is there a file within PHPBB for this to change what it sends?
I read in a few places when I searched for an extension that it is bad because HTML displays differently on different mail clients and uses more memory. I get it, but I see this everywhere else.
EDIT: Maybe just thought of a better idea. I could have all my users be auto subscribed to a mail chimp system or something, then they could opt-out of it still. I read of issues with Bluehost letting people mass emails to users. Any thoughts appreciated.
