A few things worth knowing.
Does this confirm delivery or authentication?
No. We query public DNS; we do not send messages, test your mailbox or validate an actual message’s signature and alignment. Published records do not guarantee inbox delivery.
Where do I find the DKIM selector?
In your provider’s panel or the s= field of a sent message’s DKIM-Signature header. Without it, DKIM is not queried; we do not guess selectors.
Does this measure global propagation?
No. This is a reading from the resolver used for the check. Use the DNS propagation checker to compare points. DMARC is queried at the entered domain without evaluating a message or policy inheritance.
