I created an eNewsletter in Joomla. The url is http://epulse.optionlineextend.com. It looks perfectly fine in the browser but when I bring it into Campaign Monitor I'm losing the header graphic and it's changing up the layout. I assumed that it just wasn't compatible with Joomla so I re-created it using HTML. Now basically the same thing is happening. What could I possibly be doing wrong? Thank you in advance.
Is it breaking just after import but still previewing in the browser? Or when you send a preview to your email client? I noticed that your header image is a background image, which isn't supported in a few email clients, so if it's losing the image when testing in email that could be the culprit.
