i do. love their self destructing email and password protected email options. they bought out simplelogin so paid plans get alias emails that you can receive AND send from. i'm also a fan of their active involement with the OpenPGP Working Group at the Internet Engineering Task Force (IETF).

""The result of this is the “crypto refresh" of the OpenPGP standard, as it has been dubbed, has brought about modern authenticated encryption, more secure curves, memory-hard password hashing, and more."

that said, email is inherently not secure, but we all have to use it. i recommend using simplex or better yet, in-person communication for sensitive matters
