Why should I use a custom domain?

To run high-volume campaigns, we recommend using your custom tracking domains instead of a default one.

RedTrack users not using a custom domain will be automatically assigned our default tracking domain http://rdtrck2.com which may not always suit your advertising needs.

And as we don’t take responsibility for what other users run through our default domain, there is a risk that it may potentially get flagged by antivirus and add-block software, traffic sources (for example Google is very aggressive in that question), etc.

Please see this article to find out how to set up your custom domain.
