enigma shares secrets securely

Email is not private or secure. It wasn’t designed with privacy or security in mind.
Anyone who handles your email in transit can read it,
including your ISP, a hacker, or the NSA (U.S. National Security Agency).
End-to-end (e2ee) encryption for email can be used to ensure
that only the sender and the recipient of a message can read the contents.
PGP is the best solution for secure communications with a partner that is
already using it. Asking your counterpart to start using PGP could be hard.
