Abstract: The subject disclosure provides systems and methods for sender verification for encrypted electronic messaging. The discloses systems and methods may facilitate reducing or preventing spam messages between electronic devices. An electronic device may determine, prior to sending an electronic message to another device with a first level of encryption that is higher than a second level of encryption, whether the electronic device is eligible to send the message with the first level of encryption. If an electronic device determines that it is ineligible to send the message with the first level of encryption to another electronic device, a first message from the electronic device to the other electronic device may be sent with the second level of encryption as part of an unencrypted or low encryption handshake between the devices.
