I'm building out an email and testing it across different platforms, and I've noticed it renders differently depending on where it is opened. In Hotmail and Gmail, the width of the email is 600px, so if I limit that table or image to 560px width, it looks great on those two, but then it looks terrible on Outlook and only runs about 2/3 of the way across the email. If I adjust the table to 700px, then it looks great in Outlook, but it stretches the header image in Hotmail and Gmail.
Has anyone else had this issue? I remember having to deal with it in MailChimp too a while back, but I can't remember what I did to rectify it. Any suggestions would be incredibly appreciated!
