I'm trying to change the signup email from plain text to HTML in the membership suite. I've checked the 'Use HTML in Emails?' box in the Membership Suite Setting and have created a sample signup email.
When I create a test account I received a plain text email with all the html visible. I've tried with and without body tags, with and without head tags but to no avail. Is there some special format html tag I'm supposed to be using or have I missed something?
