You can set up a custom tracking domain in BuzzStream so that you can use your own domain when tracking email opens and clicks. This offers a number of advantages over using the standard BuzzStream tracking domain, primarily by giving you more control over email deliverability and reputation management.

How to set up custom domain tracking

Setting up a custom tracking domain is fairly straightforward. To begin, just go to your BuzzStream settings:


From there, click “Tracking Options” on the left hand menu. Note that this section is only available to the admin of your BuzzStream account. If you don't see the that tab in your settings, contact your BuzzStream admin so they can continue with setup.


Now, just click “Add Domain” and follow the instructions in the new window.


One important thing to note: in order to create a custom tracking domain, you need to create a subdomain for your site (e.g. “”). Then, you’ll need to create a CNAME DNS record pointing to This may require you to get in contact with your domain manager if you don’t have these permissions (or have no clue what any of that means).

Once you’ve created your sub-domain, add the tracking domain to the field at the top of the window, then hit Validate. BuzzStream will list the tracking domain below, as well as whether it’s valid or not and which emails are associated with that domain.

DNS changes may take a while to propagate. Please allow up to 48 hours for the change to take effect (though usually it will be much faster). We will automatically start using the domain once we see the changes, even if it doesn't pass validation when initially added.

Custom domain tracking behavior

Once you've set up your custom domain, we will use it to track your opens and clicks as well as use it in any unsubscribe fields you've set up.

We will regularly validate your sub-domain, so if it disappears for any reason we will revert back to our standard BuzzStream tracking domain for future emails. However, emails that have already been sent using the custom domain will not register future events once the DNS is removed.
