If you’re an email marketer, we don’t really have to convince you about the importance of email campaigns and how much they can contribute to your marketing efforts. They are a powerful tool for marketers due to their cost-effectiveness, wide reach, and ability to offer your customers personalized engagement. With the potential for high ROI and detailed analytics, email marketing can play a critical role in your digital marketing strategy.

For your emails to give you the kind of response you’re hoping for, you need high open rates. For high open rates, you need high email deliverability — that is, these emails need to be delivered to your customers’ inboxes instead of being blocked by a spam filter. And for high deliverability, the most important metric is probably your email sender reputation

How Exactly Do You Track Your Sender Reputation? 

You can learn more about your sender reputation by monitoring key metrics such as email open rates, click-through rates (CTR), bounce rates, and spam complaints. It’s a given that you should use high-quality email marketing platforms, and reputation monitoring tools can help assess these metrics regularly.

This is where Google Postmaster Tools comes into the picture.

Imagine if you could access tons of data on your recipients using a tool created by the company whose email service is used by almost 50-80% of your target customers. Sounds too good to be true? Well, it’s for real; and it’s free

Google Postmaster Tools is a service provided by Google that offers email senders like yourself valuable insights into your email performance on Gmail inboxes. It provides data on delivery errors, spam reports, email engagement metrics, and a lot more. You can use these insights to improve email deliverability and overhaul your sender reputation, ultimately enhancing your email marketing effectiveness.

To use this tool effectively, we must first understand what Google Postmaster Tools is. After we look at its features and how it benefits you, we will run you through how to add Postmaster Tools to your website and decipher the data it offers you.

Google Postmaster Tools: What Does It Do?

Google developed Google Postmaster Tools as an analytics platform specifically for email marketers. It offers in-depth insights into the performance of the emails that land in Gmail inboxes — since a large chunk of the recipients on your email list likely use Gmail — this information is invaluable. After all, Gmail’s share of the global email market is almost 28%.

This powerful tool provides essential data on the following metrics: 

IP reputationThe credibility and trustworthiness score of your IP address
Domain reputationA score that assigned based on the trust and sender history of your specific domain name
Spam reportsThe percentage of spam reports indicate the number of instances where your recipients marked your emails as spam
Delivery errorsThis stat refers to the number of emails that faced issues preventing email delivery (i.e. bounced messages)
Authentication This number tells you how many of your emails made it past security protocol checks (for SPF, DKIM, and DMARC)
Feedback loopThe feedback loop allows you to view detailed reports on the spam complaints made by your Gmail recipients
EncryptionThis refers to the tracking of email transmission security through TLS (Transport Layer Security), ensuring private and secure email delivery

By leveraging Google Postmaster Tools, you gain the ability to fine-tune your email marketing efforts, ensuring that your email deliverability is high and also resonates with your target audience. This helps optimize the overall impact and success of email campaigns sent to Gmail addresses. 

Postmaster Tools empowers you to make data-driven decisions, maintain sender reputation, and foster better engagement with Gmail users. This ultimately results in your campaign meeting its goals  — higher CTRs, better open rates, and therefore, improved revenue.

Google Postmaster Tools stands out as an indispensable tool for maximizing the reach and impact of email campaigns among this vast and influential user base of Gmail users.

Google Postmaster Tools: Do You Need It?

Let’s imagine a scenario where you don’t use Postmaster Tools. There are so many metrics you are unaware of as an email marketer — you don’t know what’s happening with your emails, whether your customers are liking them, or maybe they are mass reporting the messages as spam — then you wonder, are the emails even making it to the inbox? You’d be flying in the dark without access to credible data on email performance.

In short, you need Google Postmaster Tools to fully understand both your deliverability rate as well as sender reputation.

What could happen if you totally ignore these metrics? Let’s look at the series of events you could possibly face by not actively tracking the statistics shared by the Postmaster Tools:

  1. You will start seeing dips in click-through rates.
  2. You will then see a drop in open rates.
  3. Some of your emails will end up in the spam folder (but you won’t be aware).
  4. This snowballs into a situation where the spam filter is not even letting your emails through.
  5. Finally, you get blacklisted.
  6. Your email service provider kicks you off their platform.

This is, of course, a worst-case scenario, but you’d be surprised how commonly it happens. Being aware of your IP reputation and domain reputation is essential to surviving and thriving as an email specialist.

Now, let’s imagine a scenario where you DO use Google Postmaster Tools on your domain.

How to Set Up Google Postmaster Tools in 2024

We’re fairly confident you’re eager to use Google Postmaster Tools and study the response to your email campaigns — so here’s how you can sign up for the service and set it up. The setup process is simple, as you only need to verify your domain and configure certain DNS records. PS: It’s a good idea to also add authentication protocols such as SPF, DKIM, and DMARC in advance.

How to add Google Postmaster Tools to your domain:

  1. First, head over to the Google Postmaster Tools website. Here, sign in using the same Google account that is associated with your domain’s email.
  2. The next step is to register your domain with Postmaster Tools, so click on the Add Domain button. Enter all the details for the domain you wish to monitor, and hit the Add button.
  3. You will now need to verify this domain as yours. You can choose between DNS TXT records or add a CNAME record to verify ownership.
  4. Follow the on-screen instructions and wrap up this process by hitting Verify. Note that this process may take some time.
  5. While you will be able to view your domain here, the status has to switch from Unverified to Verified before you can do anything more. Do not, in any case, delete the DNS record, as Google verifies it periodically.
  6. Postmaster Tools may ask you to add security protocols like SPF, DKIM, and DMARC at this point. At Campaign Refinery, this is something we insist our clients do as well; it’s a win for them, and it’s a win for us as an email service platform because it improves sender reputation and deliverability, and enables a smooth use of our advanced tools!

Understanding Google Postmaster Tools’ Metrics

After setup, you’re probably wondering how to use Google Postmaster Tools. You can see a lot of statistics on your screen, so here are the descriptions for all these metrics:

  • Spam rate: This is the percentage of emails sent by you that have been reported as spam by Gmail users. This is a metric that you need to pay close attention to as it can quickly affect your overall sender reputation. You should aim to keep this number below 0.1%, preferably at 0%. You do not get details on which users marked your emails as spam.
  • Domain reputation: Domain reputation is probably the most important factor affecting your email sender reputation. It is the measure of the trustworthiness and sending practices associated with a specific domain, and Google takes this extremely seriously. 
  • IP reputation: Google takes into account not only the domain that you use to run your email campaigns but also the specific IP address. If your IP address has been used to send “spammy” emails before, Google uses this IP history to assign you a lower score. This is why it’s critical to use a dedicated IP address over a shared IP whenever possible.
  • Delivery Errors: This is the information on email delivery issues, including bounce rates and error messages that may indicate problems with email delivery. Here, you can see specific error messages as well, like “Suspected spam” (your content is potential spam), “Rate limit exceeded” (too much traffic from your domain or IP), or “Bad or unsupported attachment” (Google can’t read your attachment and has marked it as suspicious).
  • Feedback loop: Feedback Loop or FBL is a mechanism that helps you gain insight into which specific email campaigns, content, or practices are causing recipients to flag your emails as spam. This helps in identifying problem areas and taking corrective actions.
  • Authentication: Security protocols (SPF, DKIM, and DMARC) are vital for email authentication and integrity. They verify sender identity, prevent spoofing and phishing, ensure email content integrity, and improve deliverability by enhancing sender reputation. In Postmaster Tools, you can see the percentage of emails passing through each protocol and success and failure rates for the same.
  • Encryption: This data provides insight into the percentage of your emails sent using encrypted connections, enhancing email security. If you send emails using a non-TLS channel, they will bounce. The goal is to keep this encryption percentage at 100%.

IP and domain reputation: The most critical metrics on Google Postmaster Tools

Unless you intentionally track your IP and domain reputation and investigate issues, if any, you might soon see your email marketing rapidly lose effectiveness. Google Postmaster Tools provides valuable insights into both your IP reputation and domain reputation, helping you assess your email-sending performance on Gmail:

  • IP Reputation: Google assigns a reputation score to your sending IP addresses based on factors like email volume, engagement, and spam reports. Postmaster Tools offers data on this reputation, allowing you to monitor your IP’s health. There are tiers like High, Medium, Low, and Bad — a positive IP reputation leads to better email deliverability and ensures your emails land in the inbox rather than spam folders. Postmaster Tools helps identify issues, such as spikes in spam complaints or sudden drops in engagement, and take corrective measures to maintain your sender reputation.
  • Domain Reputation: In addition to IP reputation, Google evaluates the reputation of your sending domain. This reputation depends on factors such as authentication (SPF, DKIM, DMARC), sending practices, and user engagement with your emails. By analyzing domain-level data, you can pinpoint authentication issues, monitor email engagement trends, and address any potential problems that might affect your domain’s reputation.

Overall, Google Postmaster Tools empowers email marketers to proactively manage and improve their IP and domain reputations, ensuring that their emails have a higher chance of reaching the inbox and engagaging recipients. This, in turn, contributes to the overall success of email marketing campaigns with regard to Gmail users.

The Insight You Get From Google Postmaster Tools

So now you know how to get Google Postmaster Tools up and running, and all the data is in front of you. But how do you use this data to achieve better results from your email marketing activities?

  1. If your IP or Domain score is low: Our recommendation would be to focus on your IP and domain reputation first. We suggest you segment your email lists and focus on your high-engagement users by sending them relevant emails. As you do this, ensure you’re consistently sending emails on schedule and do not, under any circumstances, suddenly increase the volume of emails. A slow and steady email domain warm-up is the only right way to go. 
  2. High rate of spam reports: This tells you that you recipients are annoyed about receiving emails they did not explicitly sign up for. Get proper consent from your subscribers before you add them to your list. Clear sign-ups also translate to better engagement for you.
  3. Low percentage of authenticated traffic: Security protocols are your friend. Adding SPF, DKIM, and DMARC protocols will benefit you greatly because it signals to ESPs that you’re not spoofing or running a phishing campaign; this greatly increases the chances of your emails landing in the inbox.
  4. Delivery errors: You can avoid being marked as spam by using high-quality content and steering clear of spam trigger words. Also, ensure that you don’t accidentally include any corrupted or suspicious files as attachments. Another way to avoid delivery errors is to ensure that you are consistent with your email volume and schedules.
