Did this ever happen to you?

One day you wake up and decide to make it the most productive day of your life. So you energetically start your day, and now it's 8 p.m. You’re disappointed with your performance and wonder what went wrong. But if you haven’t tracked your day, there’s no way to know that.

Similarly, you can’t demystify why your email campaigns are not working if you don’t track them. Fortunately, Microsoft SNDS will give you all the important data you need to track your email campaigns.

So let’s uncover what Microsoft SNDS is and how to use it to track your email campaigns.

What is Microsoft SNDS?

SNDS is a Microsoft service providing email senders with insights into their email traffic, delivery, and reputation. It helps identify and resolve issues related to email delivery, ensuring better communication between senders and recipients. Whereas SNDS full form is Smart Network Data Services.

If you have ever heard of Postmaster by Google? Then SNDS is like Postmaster, but by Microsoft. It gives you crucial data about your email campaigns measured only against users. Here’s what you can measure:

  1. Spam complaints
  2. IP reputation
  3. Emails volume
  4. Spam traps
  5. Bounce rate

This data will help you measure your campaign’s performance and will be discussed in detail in upcoming sections. But before that, let’s talk about why you should care.

Why should you use Microsoft SNDS

Outlook domains capture a good portion of 4.1 billion email users. And if the majority of your email subscribers are users, then there is no better tool to get accurate data from than Microsoft SNDS. Apart from tracking, it also helps IP owners to detect compromised servers, malware, viruses, and botnets.

Besides that, Microsoft SNDS gathers all essential data in one place. So you don’t have to juggle between multiple tools and waste your time. This helps you see where you’re in your marketing efforts and work on improving them.

But before you track any data, you’ve to follow a setup process to configure your sender IP address. Follow these steps to see (and act) how it’s done.

5 Data points Microsoft SNDS provide

It’s time to look up the numbers of your email campaigns. Let’s see what SNDS has to offer:

1. Spam complaints

Not everyone likes everyone. You may be sending valuable content to your users, but they may mark you as spam for various reasons. This report shows the number of spam complaints you’ve received from Outlook domain users. If this is higher than normal, you need to take action to control it.

You can start by creating a sunset policy and removing unengaged users. Then you can create an email cadence that’ll guide you to respect your users’ inboxes and, in turn, make them happy.

2. IP reputation

IP reputation is the measurement of the trustworthiness of a sender's IP. If your sender IP has a history of sending spam and malware to Outlook users, you’ll see a bad IP reputation. On the other hand, if you’ve maintained a good relationship with your users, you’ll see a healthy IP reputation. Again, if your IP has a bad reputation, consider moving to a dedicated IP address instead of a shared one, as it can improve your IP reputation.

3. Emails volume

This feature will help you know how many emails you’ve sent to Outlook email users (Hotmail emails also included). You can get a rough estimate of the total number of Outlook users that comprise your email list. So you may use this metric to your advantage and send personalized emails to Outlook users.

4. Spam traps

Spam traps are just what they sound. They are traps set by email providers to eliminate spammers. Unfortunately, genuine email marketers like you can accidentally become part of this group. So this feature of SNDS lets you know your spam traps report, and you need to improve it if you don’t see an acceptable score.

5. Bounce rate

Bounced emails are failed emails that didn’t make it to your users’ inboxes. This report will show you the bounce percentage of your IP address. Try keeping it below 2% to enjoy good email deliverability rates.


In the words of Valentino Crawford, “You cannot change what you don’t manage; you cannot manage what you don’t track.” So, you must track your email campaigns with tools like SNDS that give you crucial data about your email campaigns to see a positive change in your email deliverability.
