DomainKeys Identified Mail (DKIM) adds a digital signature to your emails. This proves the email hasn't been tampered with during transit.
Tamper-Proof Communications
DKIM uses public key cryptography to sign emails. If a hacker intercepts an email and changes the body or headers, the signature breaks, and the email is rejected.
Manage multiple DKIM selectors (keys) for different sending services. Rotate keys easily to stay secure.
We verify that your public key is correctly published in your DNS records so receiving servers can find it.
DKIM prevents "Man-in-the-Middle" attacks where emails are altered in transit. It guarantees the email came from you.
