Custom Tracking Domain: what it is, how it works, and why it can improve deliverability.

Setting up a custom tracking domain allows you to optimize the delivery rate, building trust among subscribers and positively impacting metrics. But how do you create a custom tracking domain? And how do you configure it on TurboSMTP? We’ll explain it to you in this guide.

To begin: what is a Custom Tracking Domain?

A Custom Tracking Domain is a domain you exclusively use to track email opens and clicks. 

If you haven’t set up a custom tracking domain but are still tracking email opens and clicks, then you are using a shared tracking domain.

A custom tracking domain can have significant benefits for your campaigns. In fact, it allows you to:

  • Preserve your sender reputation,
  • improve email deliverability (by avoiding being blacklisted due to a domain shared with spammers),
  • enhance engagement rates for your contents using branded links that communicate to the reader that it is your company (and not someone else) tracking your emails.

But if you haven’t set up a custom tracking domain yet, how can you find out which one you are using? 

Simply hover your mouse over one of the links in your email (without clicking on it) and observe the URL it points to. 

You should replace this default tracking domain with your organization’s domain. For example, if your domain is mycompany.com, you should configure a tracking domain like link.mycompany.com or x.mycompany.com or news.mycompany.com and use it with TurboSMTP.

The tracking domain is only visible to people who receive your email and hover or click on one of the tracked links. The same domain is also present in the open tracking pixel, but in this case, it won’t be visible to recipients (unless they carefully inspect the email and view its source code).

If you are one of those rare individuals who disable both open and click tracking, you can ignore this guide because the tracking domain will never appear in your emails. However, if you belong to the 99% of senders who track their metrics, a custom tracking domain could be beneficial to you.

But what are the benefits of a custom tracking domain?

The main advantages are two:

  1. A custom tracking domain creates a sense of greater reliability among the recipients of your emails. More experienced users often hover their mouse over links before clicking, and seeing a domain they are familiar with (in this case, your company’s domain) instead of a default tracking domain can help build trust and, in turn, increase the click-through rate. This is why larger companies often use custom tracking domains rather than relying on the default ones provided by their email service providers.
  2. Setting up a custom tracking domain isolates your reputation from that of other users. This means that if a spammer manages to bypass security measures and send a campaign using the same tracking domain as yours, you could end up being blacklisted, negatively affecting the deliverability of your emails. However, by configuring a custom tracking domain, you can protect yourself from the negative consequences of other users’ actions.

How to register a custom tracking domain: everything you need to know.

First of all, you’ll need to decide whether to use a subdomain or register a new tracking domain.

The best solution is generally to create a subdomain of an existing domain, as this way you can leverage its reputation. A subdomain could be something like link.yourdomain.com or x.yourdomain.com.

If you don’t have a domain that you can use for tracking (or if you can’t modify the DNS of your existing domain), you can register a new one.

Here’s how:

  1. Choose the domain registration service you want to use. Among the best options are GoDaddy and Register.com.
    GoDaddy is a reliable and reputable domain registration service known for its user-friendly interface, extensive domain options, and excellent customer support, making it a great choice for hassle-free domain registration.
    Register.com is one of the most popular services. It offers a broad range of domain extensions, hosting services, and tools for website creation. It has good customer service and features a simple and intuitive interface.
  2. Choose the name you desire to create the tracking domain. If your organization is called BusinessABC and your existing corporate domain is businessabc.com, you could opt for a domain name like businessabc.net. If the exact name is not available, you could consider alternatives like businessemail.net. 
  3. You won’t need additional services like email hosting or a website; you only need the domain. You might consider opting for WHOIS protection to safeguard your contact information, but in any case, most services offer this feature for free.
  4. After registering the name, you can set up a CNAME record for the domain, which can be found in the ‘DNS Settings’ of the chosen service.

If you’re not familiar with what a CNAME record is, you may need to consult your webmaster or domain administrator. 

Here is a support page provided by Google that explains how to configure a CNAME record.

Below are instructions on setting up a CNAME record with some of the most popular services.
