Email Security

What is DKIM?

DomainKeys Identified Mail - an email authentication method that adds a digital signature to verify email integrity.

Understanding DKIM

DKIM (DomainKeys Identified Mail) is an email authentication method that uses cryptographic signatures to verify that an email was sent by the claimed domain and hasn't been modified in transit.

When you send an email with DKIM enabled, your mail server adds a digital signature to the email header. Receiving servers can verify this signature against a public key published in your DNS records, confirming the email is legitimate and unaltered.

Why DKIM Matters for Shopify Stores

DKIM ensures your transactional emails (order confirmations, shipping updates) are trusted by email providers. Combined with SPF and DMARC, it creates a complete email authentication system that protects your brand.
