Can I have several DKIM records for the same domain?

Can I have several DKIM records for the same domain?

Yes, you can have several DKIM records for the same domain, provided they use different selectors. A selector identifies the public key used to verify a message’s signature. This allows your regular email service and a newsletter platform to sign messages separately using your domain.

Add each record under the name specified by the relevant service, using the requested record type, either TXT or CNAME. Do not combine keys into one record or replace a key used by another service. When changing a key, follow the service’s key rotation instructions and check that messages are being signed before removing the old record.
