DMARC is a relatively recent email authentication protocol created to help protect users from malicious email activities like phishing and spoofing. But does it really improve email deliverability?

In this blog, we'll explore this question in depth and look at the evidence that DMARC does, in fact, improve email deliverability.

We'll look at how DMARC works, how it helps protect users from malicious email activities like phishing and spoofing, and how it affects email delivery performance.

So let's get started!

What Is Email Deliverability?

Email deliverability is an important metric for any email marketer, as it determines your email campaigns' success. It refers to the ability of an email message to be successfully delivered to its intended recipient.

A successful email delivery means that the message has been delivered to the correct mailbox on time with the correct content.

To ensure successful email deliverability, a marketer must consider many factors, such as email content, the sender’s reputation, and the recipient’s email server settings.

Poor email deliverability can result in emails being blocked by the recipient’s email server or, even worse, being marked as spam.

Email deliverability is a complex and ever-changing process. It is essential to stay on top of the latest trends and best practices to ensure your emails reach the intended recipient.

Understanding the fundamentals of email deliverability and taking appropriate steps to improve it can help ensure that your email campaigns reach the right people at the right time with the right message.

What Is DMARC?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that helps protect an organization’s domain from malicious actors.

It is an important security measure that protects the reputation of an organization’s email domain and helps ensure that emails sent from that domain are authentic and not spoofed by malicious actors.

The protocol enables organizations to protect their email streams from being hijacked or used for malicious purposes. Furthermore, it allows companies to set specific policies that define how emails sent from their domain should be authenticated and what should happen if they fail authentication.

DMARC also provides detailed reports that enable organizations to monitor their email streams and help identify and address any issues related to email authentication. Using DMARC is an indispensable part of any organization’s email security strategy.

It is critical to understand how it works to ensure that your organization is adequately protected from malicious actors.

DMARC: Does It Improve Email Deliverability?

In short: yes.

The use of DMARC has become increasingly popular among email senders as it enables them to take control of their domain’s reputation and protect their email from being marked as spam.

It is a key tool for email senders focused on deliverability.

By setting up DMARC, senders can protect their domains from being used to send spoofed emails, which can negatively affect their reputation and increase the chance of their emails ending up in the spam folder. This, in turn, can lead to lower open rates and fewer conversions.

In addition, it provides senders with a better understanding of how their emails are being handled. It includes a reporting feature that enables senders to monitor their email performance, such as the number of emails sent, the number of emails rejected, and the rate of email authentication.

This allows for greater transparency and better control over their email campaigns.

5 Ways DMARC Improves Deliverability

1. Reduces Spoofing

DMARC helps reduce spoofing by verifying the authenticity of an email message and ensuring that the sender is legitimate.

This helps to protect users from receiving malicious emails that could potentially harm their data or computer systems.

2. Identifies Spam Sources

DMARC allows organizations to identify the sources of spam and phishing emails, allowing them to take action to block the sender or report them to the appropriate authorities.

3. Prevents Email Bounces

DMARC helps to prevent email bounces by verifying the sender’s authenticity and ensuring that the receiving server is expecting the message.

This helps to ensure that messages are delivered to their intended recipients.

4. Enhances Reputation

DMARC helps to enhance the reputation of an organization’s email domain by ensuring that it is only sending legitimate emails.

This helps to improve the organization’s deliverability rate and reduces the chances of its emails being marked as spam.

5. Improves Visibility

DMARC provides visibility into an organization’s email activity, allowing it to identify trends in email usage and quickly respond to any issues or changes in behavior.

This helps to ensure that the organization’s messages are always delivered.


DMARC is a powerful tool in the fight against email fraud and phishing.

It can help protect users from malicious emails and improve email deliverability by ensuring that emails sent from your domain are authenticated.

Using DMARC, you can ensure that your emails are sent securely and delivered to the intended recipient.

With the growing prevalence of email scams, ensuring that your emails are secure and delivered reliably is becoming increasingly important. DMARC is the perfect tool to ensure this.
