DKIM (DomainKeys Identified Mail)

In the world of email marketing, sending the right message to the right audience is not enough.

It’s also essential to ensure that the message actually reaches its destination.

That’s where DKIM, or DomainKeys Identified Mail, comes in.

If you’ve ever wondered how to improve the delivery rate of your newsletter, this term should be on your radar.

Let’s explore what DKIM is, how it works and why it’s so essential to the effectiveness of your newsletters.

What is DKIM?

DKIM is an email authentication standard that helps ensure that emails sent from a domain are legitimate and have not been tampered with in transit.

In essence, it acts as a digital seal that confirms the authenticity of the email sent, helping email servers and filters to differentiate genuine messages from possible phishing or spam emails.

How does this system work?

When an email is sent using DKIM, a unique digital signature is generated for that specific message.

This signature is attached to the email header.

When the destination server receives the email, it looks for this signature and compares it with a public key registered in the DNS of the sender’s domain.

If the two match, the email will be authenticated and will pass through the spam barriers, increasing the chances of it being delivered successfully.

The importance of this setting for email marketing campaigns

If you work in the email marketing sector, you probably send newsletters as part of your communication strategies.

Newsletters are an effective way of keeping your customers informed, but their effectiveness is reduced if they don’t reach the recipient’s inbox.

This is where DKIM becomes an indispensable ally.

By authenticating your emails, DKIM improves the delivery rate and ensures that your campaign reaches its target: the user’s inbox.

Steps for using DKIM

Implementing DKIM involves a series of technical steps that require access to the mail server and the domain’s DNS records.

The basic steps include:

• Generate a private and a public key.
• Configure the mail server to sign outgoing messages with the private key.
• Publish the public key in the domain’s DNS records.

Complementarity with other techniques

It is essential to note that DKIM is most effective when used in combination with other security protocols, such as:

• And DMARC (Domain-based Message Authentication, Reporting, and Conformance)

These three protocols together form a powerful trio that guarantees the security, authenticity and delivery rate of your emails.
