Should SendGrid CNAME records be proxied?

I have CNAME records for SendGrid and everything is working.

However, these records have a proxy status of “DNS only”.

Should these records be proxied?

If so, what are the advantages/disadvantages of doing so?

Are there any general recommendations on what DNS records should be proxied?

Currently only the A records for the domain are proxied.


If you have one or more record(s) with the type CNAME, where the Name contains _domainkey, and you are setting them to Proxied (:orange:), your email authentication (DKIM) will fall apart, which will cause your emails to be rejected.

All DNS records related to email traffic should generally be left at Unproxied (:grey:) / DNS-only.
