DKIM Record Checker

What is DKIM?

DKIM (DomainKeys Identified Mail) is an email authentication method that uses a digital signature to let the receiver know that an email was indeed authorized by the owner of that domain and has not been tampered with during transit.

Why is DKIM important?

Implementing DKIM is crucial for several reasons:

• Prevents Spoofing: It makes it extremely difficult for attackers to forge emails from your domain.
• Improves Deliverability: Mail providers like Gmail, Outlook, and Yahoo are more likely to deliver your emails to the inbox if they are cryptographically signed.
• Builds Trust: Verified digital signatures help maintain your domain's reputation with receiving mail servers.

How DKIM Works

DKIM works by adding a cryptographic signature to the header of your emails. This signature is created using a private key. Your domain's DNS contains a public key (published via a TXT record) that receiving servers use to verify the signature. If the signature matches the public key, the email is verified.
