Why would you use something like PGP if you have to send your encryption key unencrypted to the party you are sending to? And if you leave this key out on something like Twitter for example, couldn’t law enforcement or a third party if they gained access to the other persons email still read the contents of the encrypted email by using this key? Doesn’t this defeate the purpose of using encryption?

A public key only allows someone to encrypt messages that you can decrypt with your private key. The person encrypting the message can’t even decrypt it again themselves unless they have your private key.
