The electronic message delivery service obtains, based at least in part on the first information and a cryptographic key, cryptographic information that can be inserted into the electronic message. The electronic message delivery service inserts the cryptographic information and second information usable to validate at least a portion of the electronic message with the cryptographic information into the electronic message. The electronic message is transmitted to the recipient.
