DKIM generator

Email doesn’t inherit authentication. Without DMARC enforcement, any SMTP server can use your business domain name to send out email.

Without DMARC, hackers and other malicious users can impersonate messages, making them appear to come from your organization or domain. Turning off DMARC puts your users and your contacts at risk for spam, spoofing, and phishing.

DMARC ensures the destination email systems trust messages sent from your domain. Using DMARC with SPF and DKIM gives organizations more protection against spoofing and phishing email. DMARC helps receiving mail systems decide what to do with messages from your domain that fail SPF or DKIM checks.

Is your organization capable of authenticating email and thereby securing email traffic? A valid DKIM record must be published in order to use DKIM. This kind of verification is crucial to DMARC protection. To verify the DKIM Record that has been published for a certain domain, use our Free DKIM checker.

DomainKeys Identified Mail (DKIM)

DomainKeys Identified Mail is an email authentication method that allows the receiving server to check if an email was sent and authorized by the owner of the email’s domain. The email is given a digital signature which is a header that is added to the message and secured with encryption.

Why look up your DKIM record?

To verify if the DKIM TXT record is published in DNS for the domain, to check the DKIM TXT record syntax that was published and to validate the selector's DKIM public key.

How DKIM authentication works

Each DKIM-signed email message contains a DomainKeys Identified Mail-Signature header field. When a message is received, the receiving mail server can use the information in the DKIM-Signature header field to verify the message's authenticity.
