What is DKIM and Why It Matters for Email Deliverability

DomainKeys Identified Mail (DKIM) is a crucial email authentication protocol that helps protect your domain from email spoofing and phishing attacks. It works by adding a digital signature to your outgoing emails, allowing receiving mail servers to verify that the email actually came from your domain and hasn't been tampered with during transit.

Key Benefits of DKIM Authentication:

• Enhanced Email Security: DKIM provides a cryptographic signature that verifies the authenticity of your emails, protecting your domain from unauthorized use.
• Improved Deliverability: Emails with valid DKIM signatures are more likely to reach the inbox rather than the spam folder, as they're trusted by receiving mail servers.
• Brand Protection: Prevents cybercriminals from impersonating your domain, protecting your brand reputation and customer trust.
• Authentication Chain: Works alongside SPF and DMARC to create a robust email authentication framework.

How DKIM Works:

1. Your domain publishes a public key in its DNS records
2. When sending an email, your mail server signs the message with a private key
3. Receiving mail servers verify the signature using your public key
4. If the signature is valid, the email is authenticated as legitimate
