DKIM (DomainKeys Identified Mail) uses cryptographic signatures attached to email to verify that the message was authorized by the sending domain and was not altered.
What is a DKIM selector?
The selector is a label that helps receivers find the corresponding public key in DNS as a TXT record at <selector>._domainkey.<domain>.
Can NetQuery.tools auto-detect my DKIM selector?
Yes. NetQuery.tools can try common selectors for popular providers when you leave the selector blank and will surface any matches it finds.
How do I check my DKIM record?
Enter your domain and optional selector. The tool retrieves DKIM TXT records and displays their details.
Why should I monitor DKIM status?
