Under some circumstances, contrary to normal expectations, your email may not be private. Much as with passwords, it's possible to snoop email while it's traversing the network.

In addition to signing email, PGP will also allow you to encrypt your email, so that only your intended recipient can read the message. The encryption used by PGP can be very strong, virtually guaranteeing that only the recipient (or somebody knowing their secret PGP password) will be able to read your message.
