Does DMARC Improve Email Deliverability?

If you're at all interested in email deliverability, you've heard about DMARC as an email authentication method that helps you.
DMARC is a relatively recent email authentication protocol created to help protect users from malicious email activities like phishing and spoofing.

But does it truly 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 a necessary metric for any email marketer and salesperson, as it determines your email campaigns' success. It refers to the ability of an email message to be successfully delivered to its intended recipient.

Successful email delivery means the message has been delivered to the correct mailbox on time with the right content.

To ensure successful email deliverability, a marketer or salesperson 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. Staying on top of the latest trends and best practices is essential to ensure your emails reach the intended recipient.

Understanding the fundamentals of email delivery and 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 protects organizations from hijacking or using their email streams for malicious purposes. Also, 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 it is an indispensable part of any organization’s email security strategy.

It is imperative to understand how SPF, DKIM and DMARC works to ensure that your company is adequately protected from malicious actors.

5 Ways DMARC Improves Deliverability

Reduces Spoofing

Spoofing is a deceptive technique cybercriminals use to forge the sender's identity in email messages. This can lead to legitimate emails being flagged as spam or rejected by recipient mail servers.

By implementing DMARC, companies can set an exact framework for email authentication. It verifies the authenticity of an email message by aligning the sender's domain with the email's domain, guaranteeing that the sender is legitimate.

This helps to significantly reduce the chances of spoofed emails reaching recipients' inboxes.

Identifies Spam Sources

DMARC aligns the sender's domain with the email's domain and authenticates the message, providing valuable information about the source of the email. This visibility allows companies to identify unauthorized senders or compromised accounts for sending spam or phishing emails.

By monitoring DMARC reports and analyzing authentication results, companies can pinpoint the IP addresses or domains associated with spam or phishing activities. This information helps in taking prompt action to block the sender, preventing further malicious emails from reaching recipients.

In addition to blocking senders internally, it also facilitates reporting the identified sources of spam and phishing to the appropriate authorities.

Companies can provide these authorities with crucial information such as IP addresses, domain names, or email headers, which assists in investigations and enforcement actions against the perpetrators.

Prevents Email Bounces

DMARC improves email deliverability by preventing email bounces through the verification of the sender's authenticity and ensuring that the receiving server is expecting the message.

When an email is sent, it allows the receiving server to verify the sender's authenticity. Aligning the sender's domain with the email's domain confirms the email is legitimately sent from the claimed source. This verification process reduces the chances of the email being rejected or bounced by the recipient's server due to suspicions of spoofing or unauthorized sending.

Also, DMARC enables organizations to publish policies that specify how receiving servers should handle emails that fail authentication. By setting up policies such as "p=quarantine" or "p=reject," companies can lead recipient servers to place suspicious emails in separate folders or outright reject them.

This helps to guarantee that legitimate emails are delivered successfully while unauthorized or suspicious messages are addressed according to the designated policy.

Improves Sender Reputation

When a company implements DMARC, it establishes policies that specify how receiving servers should handle emails that fail authentication. Enforcing strict authentication guarantees that only authorized emails are sent from the company's domain.

This proactive approach enhances the reputation of the email domain by reducing the risk of unauthorized or malicious emails originating from it.

A positive email domain reputation is crucial for achieving high deliverability rates. Internet Service Providers (ISPs) and email service providers consider the sending domain's reputation when determining whether to deliver emails to recipients' inboxes or divert them to spam folders.

A company's email domain builds a reputation for trustworthiness and reliability by consistently sending authenticated and legitimate emails.

Improves Visibility

DMARC reports provide detailed information about email authentication results, including data on successful deliveries, failures, and potential threats.

Companies can identify patterns, trends, and potential issues affecting their email deliverability by analyzing these reports.

By monitoring DMARC reports, they can detect unusual email behavior, such as unauthorized sending, spoofing attempts, or a sudden increase in failed authentication. This visibility allows them to identify and address potential issues frustrating email deliverability quickly.

Also, DMARC's visibility enables companies to approach email deliverability proactively. By regularly reviewing authentication results and monitoring trends, organizations can make informed decisions and take corrective actions promptly.

For example, if a sudden increase in failed authentication is detected, they can investigate and resolve configuration or security issues affecting email deliverability.

Conclusion

DMARC is a great asset for delivering messages securely and in a timely manner - something that’s becoming increasingly more important as email becomes an essential part of our lives.

With its unique ability to identify false messages, prevent email bounces, and improve visibility, DMARc is undoubtedly powerful. The five ways DMARC can improve deliverability are just the tip of the iceberg in terms of the service’s full capabilities.

From improving reputation to reducing spoofing, having a secure way to deliver emails is key.
