DKIM Lookup Tool

Verify your domain's DKIM records to ensure email authenticity and prevent spoofing.

What is a DKIM Lookup Tool?

A DKIM (DomainKeys Identified Mail) lookup tool verifies the DKIM record of a domain by querying the DNS. DKIM records help authenticate the source of an email, preventing spoofing and improving email deliverability.

How to Use the DKIM Lookup Tool

  • Enter the Domain and Selector: Input the domain name (e.g., example.com) and the DKIM selector used by the sending service.
  • Click 'Check DKIM Record': The tool will query the DNS to fetch the DKIM public key associated with the domain and selector.
  • Review the Result:
    • Selector: The name identifying the DKIM key (e.g., google).
    • Public Key: The cryptographic key used to verify the email's authenticity.
    • TTL (Time To Live): The time the DKIM record is cached before refreshing.

Frequently Asked Questions

1. What is DKIM?

DKIM (DomainKeys Identified Mail) is an email authentication method that allows the receiver to verify that an email was sent by an authorized server, preventing spoofing and tampering.

2. How do I find my DKIM selector?

The DKIM selector is typically configured in your email provider's settings. It is added as part of the DNS TXT record and is often provided by services like Google Workspace, Microsoft 365, or custom mail servers.

3. What if my DKIM record is missing?

If no DKIM record is found, it means the domain is not signing outgoing emails with DKIM. To improve email deliverability and security, you should generate a DKIM key and add it to your DNS records.
