I test an email tempate by using Outlook express in HTML mode, copy the HTML code into the email and email to my OE, Hotmail and Gmail accounts.
I tried this with a free email template and it only displays correctly in OE. Google does not show any of the body styliing of the email, hotmail flags the images used and dupes the header at the bottom of the email.
not good results, what changes are required in general to fix these problems? is this a good way to test email templates?
