❓ FAQ

What is a DKIM record?
DKIM (DomainKeys Identified Mail) record is a DNS TXT record containing a public key used to verify that an email was actually sent by the domain owner and hasn't been tampered with.
What is a DKIM selector?
A DKIM selector is part of the DKIM record name, formatted as selector._domainkey.domain.com, specifying which key to use for signing. Common selectors include google, default, s1, s2.
How do I find my DKIM selector?
Check the DKIM-Signature header in the raw email, where s= value is the selector. Google Workspace uses 'google', Microsoft 365 uses 'selector1/selector2', SendGrid uses 'smtpapi'.
What do v= and k= mean in DKIM records?
v= indicates DKIM version (usually DKIM1), k= indicates key type (usually rsa), p= contains the actual public key data. These tags together form a complete DKIM record.
