We are currently experiencing an issue with email, which will show up as you either not receiving emails from 99designs, or them arriving very slowly. It seems AOL customers are especially affected.
We have implemented a fix which should fix the problem, please let us know if anyone is still experiencing problems.
Update 18-Feb: We have fixed all of the email problem, although due to some issues with our DNS configuration, certain mail services, such as hotmail, yahoo and godaddy email will continue to experience some delays for the next 24 hours. I have contacted each of these and asked them to speed things up, so its possible that it might be quicker than this. Sorry guys, thanks for your patience!
