DKIM

What is DKIM?

DKIM (DomainKeys Identified Mail) is an email authentication method that uses digital signatures to verify that an email was sent from an authorized server and hasn’t been tampered with during transit.

‍

Why is DKIM Important?

DKIM helps:

• Ensure Email Integrity: Verifies that the email content hasn’t been altered.
• Improve Deliverability: Increases the likelihood of emails reaching the inbox.
• Build Trust: Shows recipients that your emails are legitimate.

How Can I Use DKIM?

1. Generate a DKIM Key: Create a public-private key pair.
2. Publish the Public Key: Add it to your DNS settings.
3. Sign Outgoing Emails: Configure your email server to sign emails with the private key.
