Validate your DKIM (DomainKeys Identified Mail) record to ensure your emails are properly signed and authenticated.
Enter your domain and selector to check if your DKIM record is properly configured
DKIM (DomainKeys Identified Mail) is an email authentication method that allows the receiver to verify that an email was actually sent and authorized by the owner of that domain. It uses cryptographic signatures to ensure email integrity.
When you send an email, your mail server signs it with a private key. The recipient's server then uses your public DKIM key (published in DNS) to verify the signature. This proves the email hasn't been tampered with and confirms its authenticity.
Generate a public/private key pair using your email service provider or mail server.
Add the public key as a TXT record in your DNS with the selector name.
Configure your mail server to sign outgoing emails and verify with this tool.
