What is DKIM Record Checker?

DKIM Record Checker scans common selectors to find your domain's DKIM (DomainKeys Identified Mail) records. DKIM adds a cryptographic signature to outgoing emails, proving they weren't altered in transit and came from your domain.

How to use this tool

  1. Enter your domain name.
  2. The tool checks 9 common selectors (default, google, selector1, selector2, k1, mail, dkim, s1, s2).
  3. See which selectors have DKIM records published.
  4. Review the DKIM record content for each found selector.
  5. If no records found, you need to configure DKIM with your email provider.

Frequently asked questions

What is DKIM?
An email authentication method that adds a digital signature to outgoing messages. The receiving server verifies the signature using a public key published in your DNS. This proves the email wasn't modified after sending.
What is a DKIM selector?
A label that identifies which DKIM key to use. Each email provider uses a different selector — Google uses "google", Microsoft uses "selector1"/"selector2". The selector is included in the email header so receivers know which DNS record to check.
Why were no DKIM records found?
Either DKIM isn't configured, or your provider uses a non-standard selector. Check your email provider's documentation for the correct selector name. Some providers like SendGrid use randomly generated selectors.
Do I need DKIM if I have SPF?
Yes, you need both. SPF verifies the sending server, DKIM verifies the message content. DMARC requires both to work together. Without DKIM, your emails are more likely to be flagged as spam.
