What is a custom tracking domain and what does it do?

In order to track certain things like email opens (for example - and link clicks in the future), we insert special code into the body of your emails.

That special code is generally in the form of a URL - for example: xyz.inreg1.com

Now while we keep changing that URL every once in a while, that same domain is used by every Instantly customer - unless you setup a custom tracking domain.

When you setup a custom tracking domain, the special code that we insert will use your specified domain instead of ours.

And so it will be unique - which helps ensure that your sending reputation and deliverability are completely isolated from the rest of the accounts.

Think of it as bringing your own toothbrush on a road trip rather than using one

that's shared by multiple people. Only you get to use it, which prevents any dental problems that you could get by using a shared one.

When you add a custom tracking domain, it essentially works as a proxy/mask for

the tracking end-point and it isolates your sender reputation from the rest of the

user base... and so in a nutshell, always use a custom tracking domain.


How to add a custom tracking domain to Instantly?

Start by logging in to your Instantly and Namecheap accounts.

In Instantly, open the Settings window for the account that you are setting up Custom Tracking Domain for.

Check the Custom Tracking Domain box.

In the text field, enter inst.yourdomain.com

Go to Namecheap DNS records for your domain.

Create a new record by clicking on Add New Record:

Choose CNAME for the record type. Host: inst Value: prox.itrackly.com

Click Save all changes.

A minute or two is needed for records to propagate.

You can go back to Instantly and click Check Status:

If everything is set up correctly you will receive the following notifications below the Check Status button:

  • CNAME Verified

  • SSL Verified

After the records have been verified, don't forget to Save Changes in the same window.

For other sending accounts with the same domain, you can go ahead and update Custom Tracking Domain settings by entering the same tracking domain or subdomain that you've just created.

For instance, use inst.domain1.com for all sending accounts with domain1.com and inst.domain2.com for all sending accounts with domain2.com.
