About DKIM Selectors

DKIM records require a "selector" to identify which key to use. Common selectors include "default", "google", "k1", or "selector1". If you don't know your selector, try the "Scan Common Selectors" button to automatically discover available selectors.

Why use the DKIM record checker?

DKIM records digitally sign your emails to prove authenticity and prevent tampering. Our tool helps you ensure your DKIM records are properly configured and secure.

Understanding DKIM Records

DKIM (DomainKeys Identified Mail) is an email authentication method that uses cryptographic signatures to verify email authenticity and prevent tampering.

description
DKIM Record Location
DKIM records are TXT records published at "selector._domainkey.domain.com" where "selector" is chosen by your email provider.
key
Public Key Cryptography
DKIM uses public-key cryptography with RSA or Ed25519 algorithms to sign email headers and verify authenticity.
label
Selector Management
Selectors allow multiple DKIM keys per domain and enable key rotation without changing the main DKIM setup.
security
Signature Verification
Email receivers use the DKIM record to verify that email content hasn't been modified during transit.

DKIM Best Practices

Follow these guidelines to implement effective DKIM authentication that improves email deliverability and security.

check Use Strong Keys

Use RSA keys of at least 2048 bits or Ed25519 keys for strong cryptographic security. Avoid deprecated algorithms.

check Regular Key Rotation

Rotate DKIM keys periodically for security. Use multiple selectors to enable seamless key rotation without disruption.

check Test Configuration

Regularly test your DKIM records and verify that email signatures are being generated and validated correctly.
