The subject of HTML emails usually ends up in a 2 hour long discussion about all the hacks and work arounds that need to be put into place to get it working in the series of test mail clients and online “clients” that you’re supporting.

That list of course could be tiny, or very extensive.

Whilst trying to find out why Hotmail wanted to fill my email with lots of margins breaking the layout, I Googled to find an answer and came across http://www.viget.com/inspire/hotmail-image-problems-in-html-emails/

From here, I visited the Email Standards Project which gives a good overview of mail clients and their current ability to ignore all the code you’ve been slaving over.

And I’ll leave you with a Flickr group depicting the hatred of GoogleMail’s current rendering:
