When you get that email you input what the date (or also time) as the key. As long as no-one knows that you use the date. Theoretically you could have Alice and Bob have a shared date/time encryption key that is generated from Alices and Bob's public keys, and thus Alice and Bob don't know what that key is. It encrypts the time then encrypts the message with the encrypted time then encrypts the time with Bob's public key to ensure total security. After the message and ecrypted time is sent, Alices computer wipes the memory and Bob now has the key/keys to decrypt it. The moment Bob decrypts the message, all memory of the keys is lost. If Alice and Bob want to communicate again, the date will always be different, and thus instant self-destructing keys.
