Why DMARC Is Important for Your Email Deliverability

Email Deliverability Simplified | The Blog

Maybe you’ve heard about DMARC but you didn’t know that your email deliverability depends on it. In this article we will cover what DMARC actually is and how it can be helpful when it comes to email deliverability.


What is a DMARC Record?

DMARC (Domain-based Message Authentication, Reporting and Conformance) creates a clear image that shows Internet Service Providers or ISPs how to stay clear of malicious email practices. Domain spoofing may be one of those practices, created to obtain personal information from the people receiving the email.

Email senders are allowed to pin point the ways in which to handle emails that have not been authenticated using SPF (Sender Policy Framework) or DKIM (DomainKeys Identified Mail).

Senders also have other several options. They can send those emails straight to the junk folder or just block them all together. By taking these actions, Internet Service Providers can do a better job in identifying spammers and stop unwanted emails from entering the inboxes of consumers, and at the same time, they can minimize false positives by providing a more exact authentication report that leads to overall transparency in the marketplace.

It’s important to know that not all servers perform a DMARC check before accepting a message, but on the other hand, the majority of ISPs do it, and as far as we know, implementation continues to grow. DMARC, along with a dedicated IP is a great way to protect your sender reputation from malicious attacks.


How does a DMARC Policy work?

So, we’ve talked about what DMARC is and what it does, but another important question is: how does it work? Keep reading because we got you covered.

The established SPF and DKIM standards are the pillars of DMARC protocols when it comes to email authentication, alongside the pretty well-known Domain Name System or DNS. Let’s see how this process plays out:

  1. A domain administrator publishes the policy defining the authentication practices of an email, also explaining how mail servers that are on the receiving end should handle violations. The DMARC policy is also listed as part of the domain’s overall DNS records.

2. When an incoming email is received, the inbound mail server uses DNS to check for the DMARC policy for the domain. Then, the server evaluates three key factors:

    • If the message’s DKIM signature is valid.
    • If the message came from an IP address that is allowed by the domain’s SPF
    • If the headers in the message are properly “domain aligned”.

3. By using these data, the server can apply the sending domain’s DMARC policy to choose whether to accept, reject or flag the email. After the proper disposition for the message is determined using DMARC policy, the receiving server will report the outcome to the sending domain owner.


Why Email Deliverability depends on a solid DMARC Record

While using DMARC, Internet Service Providers like Gmail are less likely to place your campaign in the spam folder or even block the emails you send due to the fact that a DMARC policy you create is confirming that it is actually you who is sending the mail message. DMARC is making your emails trustworthy in the face of online servers, by verifying your email sending domain. This allows you to send higher quality outbound email campaigns, maintain your reputation and improve your email deliverability.
