I recently updated an email template in Marketo for a client of ours. The client requested removing some photos and other elements, but the template code contained a lot of lines of code for something as simple as 1 photo. The emails seems to work great, but does not render properly in Yahoo. I spent a lot of time in the code looking for the problem, and another developer told me the template CSS was to blame. However, today our client is saying we can fix the issue in our html.
Has anyone had this problem with email templates not rendering correctly in Yahoo email after editing the templates?
