# DKIM

This is an abbreviation of DomainKeys Identified Mail, or domain key signed email. DKIM is a type of electronic signature that protects email recipients from spam. Email signed with DKIM has no claims on end users. You can generate this key/signature yourself in most [freemail](https://www.bartvisions.cz/en/slovnikovy-pojem/freemail-2/) services (in Gmail, you can generate the key via Apps – Gmail – Authentication – DKIM), preventing your emails from falling into spam or promotions for your recipients. DKIM works on a similar principle to SPF, but is a more modern and secure way to verify the sender’s identity. The DKIM signature is decrypted by the email service itself based on the public DNS key of the domain.
