To build complex HTML Mail-Templates (multi-columns with tables, bullet proof buttons …) and make these modules editable for editors, who don’t want to copy and paste such confusing constructs and probably are missing spaces or tables, it would be absolutely great to restore the repeater option (http://designers.hubspot.com/docs/tutorial/how-to-create-a-repeater-module-with-hubl). From my point of view this function is really essential for a correct displayed Mail, which should be userfriendly, too. Perhaps you have a better advice. Creating templates with all possible cases is not the smartest solution (my opinion). Thanks for your support.
Best Regards!
