Dmail is a Chrome extension which allows you to un-send, or revoke any emails you send through your Gmail account. The service was launched by the same brainiacs that brought us the Delicious social bookmarking tool.

Self-destructing email isn’t exactly a new thing. Google itself rolled out a feature that lets you un-send a message once you’ve sent it. The only issue with Google’s built-in service however, is that you only have 30 seconds to change your mind about sending an email to someone. Dmail lets you revoke emails whenever you like. I took it for a quick spin to see what it’s like, and I have to say, it’s an incredibly convenient way to make all your outgoing communication more secure. It also happens to be ridiculously easy to use.
