What is a DKIM record?
DKIM (DomainKeys Identified Mail) adds a cryptographic signature to your outgoing email. The public key is published as a DNS TXT record at selector._domainkey.yourdomain.com. Receivers use it to confirm the message was not altered and really came from your domain.
Finding your selector
The selector is set by your email provider. Common ones include google (Google Workspace), selector1 and selector2 (Microsoft 365), and k1 (Mailchimp). You can find the exact selector in the DKIM-Signature header of an email you have sent.
