Concepts and technologies are disclosed herein for providing and using a secure email verification service. A processor can receive verification data and identify a user identifier associated with a sender identifier included in the verification data. The processor can generate a hash value of the user identifier, a global time indicator, and message-specific data; and send the hash value to the sender device. The processor can receive a verification package that comprises the hash value and a recipient device version of the verification data and generate a new hash value of the user identifier and the recipient device version of the verification data. The processor can compare the new hash value to the hash value to determine if the email message should be verified.
