How DMARC affects Email Sender Reputation

For marketing departments, maintaining high email delivery rates can feel like an uphill battle. And with pesky metrics like engagement rates, spam complaints, and unsubscribes constantly posing threats, it can even feel like an all-out war. 

We’ve already discussed how DMARC affects Email Deliverability in general. Now let’s take a closer look at a key factor in keeping high delivery rates: Email Sender Reputation.

What is Email Sender Reputation?

Email sender reputation is a complex score calculated by Email Service Providers (ESPs), which helps determine the fate of your email in terms of delivery. Essentially, it measures how trustworthy an email sender is over time. This trust—or lack thereof—is determined by a variety of factors, including:

1. IP Address and Domain Reputation : Frequent high-volume sends from unknown IP addresses or domains can raise red flags, potentially identifying the sender as a spammer.
2. Email Engagement Metrics : High open rates and low bounce rates signal positively to ESPs, indicating that recipients value the content they receive from you.
3. Spam Complaint Rates : The frequency with which recipients mark your emails as spam directly impacts your reputation. High complaint rates can quickly erode trust.
4. Mailing List Practices : The quality and cleanliness of your email list (e.g., use of double opt-in methods, regular list cleansing) can affect your reputation scores.

The Importance of a Strong Email Sender Reputation

A strong sender reputation means better email delivery rates to inboxes, while a poor reputation can lead to emails being diverted to spam folders or outright blocked, reducing the effectiveness of your campaigns.

When it comes to deliverability, it can be a bit of a chicken-and-egg situation. On the one hand, improving your Email Sender Reputation increases your email deliverability. However, on the other hand, you need to increase your email deliverability in order to improve your Email Sender Reputation. 

That’s why it is crucial to maintain best practices when it comes to your email campaigns. Of all the email best practices available, at the top of the list is DMARC.

DMARC – What is it?

Domain-Based Message Authentication, Reporting & Conformance (DMARC) is an email authentication protocol that improves email deliverability by verifying the identity of an email sender (usually the identity of a company rather than an individual). 

By verifying the sender’s identity, spoofing risks drop dramatically, and customer trust goes up. This is a big win in the eyes of Email Service Providers. 

It’s also a massive help on the sender side, because DMARC gives you direct visibility into the specifics of which emails are delivered (and why). It can eliminate a lot of the guesswork when it comes to optimizing email deliverability for your campaigns. 

How does DMARC affect sender reputation?

Although DMARC itself does not directly alter your reputation score, it does influence several factors that collectively contribute to an improved reputation. Here’s how:

1. Increased Trust and Credibility : Implementing DMARC signals to ESPs and recipients that your emails are secured. This can help establish your domain as trustworthy and score points for your Email Sender Reputation.
2. Alignment with Best Practices : Adopting DMARC aligns your domain with industry standards for email authentication. Since DMARC is becoming a necessary requirement by more and more ESPs, adherence to these standards reflects well on your domain.
3. Proactive Issue Identification : The reporting feature in DMARC allows you to monitor email activities related to your domain. By identifying and addressing issues quickly, you can maintain a clean email sending history.
4. Enhanced Email Authentication : By using DMARC in conjunction with SPF and DKIM, you ensure that only verified emails are sent from your domain. This reduces the likelihood of your domain being used for phishing or spoofing attacks.
5. Reduced Spam Complaints : With DMARC, unauthorized emails are less likely to be sent from your domain, decreasing the chances that recipients will mark them as spam.
