What is Google Postmaster?

The Google Postmaster is a performance measurement tool that tracks and analyzes email campaigns of Gmail users. It provides the performance data only against Gmail users. The factors you can measure are:

  1. Domain reputation

  2. IP reputation

  3. Delivery errors

  4. Spam rate

  5. Authenticated traffic

  6. Encryption

We will discuss these factors in detail later in the guide but first, let’s discuss the benefits of using Google Postmaster.

Why should you use Google Postmaster?

Gmail is the email client of choice for a good portion of email users for several reasons:

  • With a market share of 27.4%, Gmail held its ground as one of the most popular email clients.

  • If you regularly send emails to your email list, most of them probably are Gmail users. So, Gmail is already familiar with your sending IP address and domain name.

  • Since Google owns Gmail and Postmaster, it can take the performance data from Gmail and provide that in the Google Postmaster. So you’re getting accurate data straight from one of the largest inbox providers in the world.

  • Google Postmaster also helps you track many different criteria all in one place. This eliminates the need to juggle multiple apps making the tracking process easier.

But before you do any tracking, you’ve to set up your domain and verify the details. Then only Google can know which domain you own and provide you with the right data. Let’s learn how to add your domain to Google Postmaster.

How to set up Google Postmaster?

Follow these steps to set up your domain on the Google Postmaster:

  1. Visit the and log in with your Gmail account.

  2. Click the “+” icon at the bottom right of the screen.

  3. Enter your authentication domain name in the popup that appears next.

  2. The below image shows how you can add your record to a GoDaddy domain name. It will be similar for other domain name providers as well.

  1. Once you’re done adding and verifying the domain, wait for some time until Postmaster collects your associated data. Once it’s done with that, you can explore the tools it offers and measure your email campaigns.

Let’s learn what it offers and how it can benefit you.

6 beneficial tools that Google Postmaster offers

Here we will discuss 6 vital Google Postmaster tools that can help you track and analyze your email marketing performance:

1. Domain reputation

Domain reputation is how inbox providers see your domain name. If the emails you sent from have received significant spam complaints, your domain reputation will be poor. Instead, your reputation will be good if you send helpful emails with great open rates from your domain.

Google Postmaster will rate your domain reputation as bad, low, medium, or high. If it is nearer to the bad spectrum, you should work hard to improve it. If it is nearer to the high spectrum, you should work hard to maintain it. Either way, this feature gives you a score to measure and improve your reputation.

2. IP reputation

Your emails are sent from a device with a particular IP attached. If many spam emails are being sent from that IP, the inbox providers will assign a negative reputation to it. On the other hand, if it is a dedicated IP address and well-maintained, it will earn a good reputation from inbox providers.

Again, the Google Postmaster will rate your IP’s reputation as bad, low, medium, or high. If it is on the lower end of the spectrum, improve it. If it is on the higher end, maintain it.

3. Spam rate

Spam rate helps you identify the percentage of users marking you spam. These people may not have found your content helpful. So if this number is significantly high, you'll have to make some tweaks to your email campaigns. Here are some suggestions:

  1. Find the right email cadence and follow it.

  2. Form a sunset policy and identify disengaged users.

  3. Create a suppression list and cut your ties with these users.

You’ll see a positive change in your spam rates if you follow these three steps.

4. Delivery errors

Not every message reaches your user’s inbox, and there can be many reasons for that. The delivery error dashboard shows you the percentage of emails that didn’t make it to the users’ inboxes and got rejected – temporarily or permanently. Follow these steps to lower this rate as much as possible:

  1. Set up your DMARC, DKIM, and SPF record.

  2. Don’t add a malicious attachment to your emails.

5. Authenticated traffic

In this dashboard, you’ll be able to see how many emails have passed the DMARC, DKIM, and SPF records versus the total number of emails that attempted to pass. This dashboard has three graphs meant to show the data of these three records.

  • SPF graph: This graph shows the percentage of emails that passed SPF vs. all emails from that domain that attempted SPF, excluding any spoofed emails.

  • DKIM graph: This graph shows the percentage of emails that passed DKIM vs. all emails from that domain that attempted DKIM.

  • DMARC graph: This graph shows the percentage of emails that passed DMARC vs. all emails received from the domain that passed SPF or DKIM.

6. Encryption

Emails must be encrypted to keep your data safe from third-party intruders. And for that reason, this graph shows you the number of incoming and outgoing emails that were encrypted. The Transport Layer Security (TLS) mechanism is used to check the encryption of emails.

The encryption graph should always be at 100%, and if it isn’t, it can become a serious security and deliverability threat, and you need to get it sorted quickly.

That’s it. Congratulations on making it this far!
