As Jason Rodriguez over at Litmus has put it, "the world of email design is full of hacks." We are a community continually forced to find the small hacks that make a world of difference to us and our clients.
I have yet to find a place where all of the brilliant hacks the members of our community have discovered can be easily found. With such a creative, intelligent, and dedicated community the potential for a collaborative archive of sorts is very exciting.
And so, I bring you the HTML Email Hacks repository. I hope we can use this as a way to archive and localize useful hacks, email templates, code snippets, etc. So please feel free to fork and make any contributions you think would be helpful to the community or for your own work (you never know who could find it useful!)
