Silent Mail email service, founded by Silent Circle, has decided to shut down. The decision, announced in a blog post, comes on the same day that Lavabit, another secure email service, decided to close because it cannot guarantee users' security.

Silent Circle has not received any “subpoenas, warrants, security letters, or anything else by any government”. By acting now the post says Silent Circle and users can avoid dealing with them in the future.

The post mentions Lavabit (the email service that whistleblower Edward Snowden used ) and its unwillingness to “be complicit in crimes against the American people” and says Silent Circle can “see the writing the wall” and has therefore “decided that it is best for us to shut down Silent Mail now.”

Silent Circle says it is still working on “innovative ways to do truly secure communications”.
