Every time you send an email campaign, ISPs monitor your sending practices and assign a reputation to your domain and IP address. This reputation is based on several factors from spam complaints, to sending volume and everything in between, and impacts if you are let into the inbox, or sent straight to spam.

Google is famous for having its own tools and rules, not just for evaluating your sender reputation, but for things like inbox placement. That’s why we’ve integrated Google Postmaster Tools into our Mailgun Optimize deliverability suite. Here’s how you can benefit.

Overview of Google Postmaster tools

Google Postmaster Tools is a free platform that can provide marketers with valuable insights into the performance of their campaigns for the messages sent to Gmail users. It offers metrics, data, and insights that can be used to improve deliverability and campaign success.

Here are a few of the key features of Google Postmaster Tools:

  • Dashboard: The dashboard provides an overview of your email campaign health which includes your IP and domain reputation and spam rate. It also displays a 30-day snapshot of your delivered message’s inbox and spam rates.

  • Reputation: The reputation tab shows the reputation of your IP address and domain name, as well as flags any spam complaints and provides an authentication status.

  • Deliverability: The deliverability tab has data on how your emails are delivered to Gmail users, including the percentage of emails delivered to the inbox and spam folders, and the number of bounces.

  • Authentication: This provides details on how your messages are being authenticated including DKIM and DMARC.

How monitoring your IP and Domain reputation improves deliverability

Email deliverability can be a scary topic for senders at scale. Identifying an issue with inbox placement isn't always easy, without key insights into reputation, delivery, and engagement it can be hard to first identify if there is an issue. If you are able to identify a deliverability issue, understanding the root cause(s) can be the next challenge. Because deliverability is such a complex topic, there is a long list of potential causes, ranging from the email content itself, to the way you have configured your traffic, and everything in between.

With access to your IP and domain reputation, you can get near-instant insight into any deliverability issues that might be on the horizon. The quicker you identify an issue with your sender reputation, the quicker you can find the source and avoid spam placement or even worse, like landing on a blocklist.

The impact of domain health on your sender reputation

Your sender reputation measures how trustworthy you are. It indicates to ESPs if your messages are legitimate, or if they are spam. Domain reputation is built over time by following best practices for deliverability. Some key factors that can work against you are:

  • Sending frequency: Send too many emails too often and you can be flagged for the spam folder.

  • High complaint rates: How your recipients interact with your messages matters. If your subscribers mark your emails as spam, or report them as unwanted, it impacts your sender reputation. Learn how to use list management to prevent this.

  • Authentication: Authentications like DMARC, DKIM, and SPF are protocols and certifications you can adopt that validate your sender identity based on DNS records and other documentation. They signal to ESPs that you are a legitimate sender.

How Mailgun Optimize can help: Google Postmaster Tools integration

With Google Postmaster Tools now integrated into the Mailgun Optimize suite, you can access essential testing and monitoring tools directly from within your account, keeping all your email metrics centralized. Our Google Postmaster integration reports on:

Delivery errors – The Delivery Errors dashboard will give you a quick look at your delivery rate so you can get a closer look at the volume of messages that were rejected or temporarily failed with the actual reason as to why the failure occurred. For example, if your messages were rejected due to suspected spam, you will be able to see that in the dashboard.

IP and Domain reputation – Your domain and IP reputation dashboard will provide invaluable insight into the overall health of your sender reputation for Gmail accounts. This will help you get ahead of reputation issues and keep your emails landing in the inbox.

User reported spam rate - The Spam Rate dashboard tracks how many users are reporting your messages as spam. Tracking complaints coming from your recipients helps you identify issues within your email program that can be fixed through testing and iterating.

Authentication success rate - The authentication success rate is the percentage of your emails that pass SPF, DKIM, and DMARC authentication against all received traffic that attempted authentication. With Mailgun Optimize you have a convenient place to monitor your authentication status across domains over a selected period of time.
