Whenever you get a notification email from Facebook, such as for a tagged photo, those emails can be encrypted with plain text communication protocol STARTTLS, creating a more secure connection.

In May, Facebook said that just 28.6 percent of such emails sent out were protected with STARTTLS, but now that number is up to 95 percent.

Facebook’s Michael Adkins, a Messaging Integrity Engineer, explained what led to the shift of STARTTLS encryption:

We previously reported that only 28.6% of our outbound notification emails were successfully encrypted and passed strict certificate validation (58% if you count opportunistic encryption). Since STARTTLS encryption requires both sides to deploy it, we encouraged others to take the next step. As a result of recent changes by major providers, most notably Microsoft and Yahoo, 95% of our notification emails are now successfully encrypted with both Perfect Forward Secrecy and strict certificate validation.
