DKIM is Securing Your Email Content

When sending emails to your customers, it's not enough that messages reach the inbox - you also need to ensure the content hasn’t been altered along the way. That’s where DKIM helps secure your email integrity.

What Is DKIM (DomainKeys Identified Mail)?

DKIM applies a digital signature to each outgoing email, verifying that the content has not been altered in transit and that the sender is authorized. This adds a layer of trust and protects your email integrity.

Why DKIM Matters

If anyone tries to tamper with your message after it's sent, DKIM verification will fail. Email providers use this check to prevent altered or malicious messages from reaching recipients.

Example of DKIM in Practice

Your DNS publishes a DKIM record that includes a cryptographic public key. When you send an email, your system signs it using a private key. The recipient’s mail server checks this signature against your published key.

Why Businesses Need DKIM

For any business that sends email, DKIM helps:

• Verify sender identity

• Prevent tampering and data manipulation

• Improve deliverability and inbox placement

• Build trust with recipients
