Why isn't my k1._domainkey TXT record being recognized?

I was following the instructions provided by Mailgun to add DNS records necessary for sending. However, Mailgun won’t recognize k1._domainkey TXT record. How come? Is domainkey supposed to be a placeholder? Can somebody please help me fix this problem. My domain is and I have attached two picture belows. The first picture shows Mailgun’s instructions and the second picture shows my records.


I ran a command on the VPS to check the record and it is indeed visible. Check the link below:

In addition to what has already been mentioned, as far as I can see from this external DNS checker, your TXT record appears to be added two times:

This might also cause an issue with the validation, if this is the case, I would recommend deleting the duplicate DNS record.



Hello there,

DNS changes might take up a few good hours in order to update. If after a few hours the domain is still not verified then you can double-check the DNS records for any misconfiguration.

You can check Mailgun’s docs for the verification process here:

Hope that this helps!
