I know theres AES and PGP, but all electronics stuff still has backdoors. You can’t backdoor a piece of paper and a writing utensil.

This is how all modern cryptography works. A deterministic cipher is functionally no different from pig Latin when it comes to actual security. An electronic solution like public key cryptography is infinitely more secure. If you’re especially paranoid you can generate the cryptotext locally and send it by email; that would be much safer than anything you could achieve by hand.
I would think mailing a flash drive with the key and sending the message electronically would be safer. One requires knowledge of the other.
