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

In order to track certain things like email opens and link clicks, 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.


  1. Log in to your Instantly account in one tab, and your Google domains in the other.

  2. In your domain section, click on Manage

3. From the left-hand side menu, click on DNS

4. In the Custom records section, click on Manage custom records

5. Click on Create new record

6. Go to Instantly account settings, check the Use custom tracking domain, and copy the data from there for a new record:

7. Paste the data and click Save:

Host name: inst
Record type: CNAME

TTL: 3600

Data: prox.itrackly.com

8. In Instantly, in the account settings, under Your tracking domain or subdomain enter: inst.yourdomain.com (change it with your sending domain).

Then, click on Check Status.

9. After both SSL and CNAME records have been verified, you can go ahead and save changes.
