What is DKIM?

DKIM adds a digital signature to every email you send. Receivers look up the public key in your DNS and use it to confirm the message really came from your domain and wasn't altered.

What's a selector?

A domain can have several DKIM keys, one per sending service. The selector names which key to look up. You'll find it in the s= part of the DKIM-Signature header of an email you've sent.
