How Do Cryptographic Keys Work in Email Marketing?
When sending an email, the marketer uses a cryptographic algorithm to encrypt the content using a key. The recipient then uses a corresponding key to decrypt the message. This ensures that even if the email is intercepted, the content remains unreadable without the decryption key. This process not only protects the content but also ensures the authenticity of the sender, reducing the risk of phishing and spoofing attacks.
