I send a lot of HTML emails. The problem with GMail is, if there are more than one emails with the same subject, it hides some similar content and shows a "..." to show the "trimmed content". This screws up with my formatting.
If changing the subject is not an option, is there is any way to avoid this behaviour?
Edit: I should clarify that I programmatically send emails using Amazon SES from a php script. That is why I posted the question in Stack Overflow.
