Another one of those pesky email clients not working properly. With the advent of MailChimp and cool CSS stuff, you kinda get lazy. I did and forgot to add the old school version of layouts on tables. I only added the style=’margin: 0 auto’ but Hotmail web based client actually stripped that out!
Add align=’center’ as well as the style=’margin: 0 auto;’. Another simple thing I know I will forget – hence adding it here.
