Problem 1: Servers
You rely on narcoleptic servers, and quite honestly, this shouldn't even be a problem because all other email providers seemed to have solved it. Even email providers offering instant messaging capabilities, a feature you're just now looking into, crash less often than you, while being used more frequently. Your servers go down more often than a prostitute who just gave up turning tricks for a better life and then tragically suffered a stroke causing her to fall down a lot.

Problem 2: Security
Remember when we were all sophomores and Rob hacked into everyone's email accounts and registered with hundreds of fetish porn sites and then we were inundated with amputee erotica and we thought it was a pretty good prank but then Rob ended up leaving school for that sex addict rehabilitation center in Oregon? I think we all learned a valuable lesson that year: Your security was terrible. Rob was not a genius; his crowning achievement of technological wizardry was memorizing cheat codes for SimAnt. He hacked into our email just by testing the password "eh" and it worked... on every account. You were responsible for what is still considered, the most widespread security incident in the history of the Web.
