This past week there have been stories of both AOL and Yahoo losing a ton of email (thousands of emails for AOL, millions for Yahoo Japan). This comes just a few months after Google had some problems with mass email deletions in Gmail. While the convenience these services provide is fantastic, all of these stories of lost emails should act as a reminder that you probably shouldn’t trust any of these providers alone to care for your email.
The sad thing is that these providers do -not- make it easy to back up your e-mail at all. In fact, I am not even sure it’s possible with some of them. Their goal is to obviously keep you, by making it inconvenient to leave. If that’s the case, they should work towards making sure you never have to deal with lost e-mail.
