In order to point a domain to Postalytics for a pURL Campaign, you’ll need to add an ‘A‘ Record with a Host value of ‘*’ to your domain registrar’s DNS Zone File.  This will point everything except subdomains that are already assigned to our IP address:

Log in to your hosting company’s admin dashboard, navigate to your domain’s DNS settings, and add an ‘A’ Record with the following values.

  • Host: *
  • Points to:
  • TTL: 1 Hour

Below you will be able to view what your  ‘A’ Record should look like when entered into the dashboards of some popular web hosts including Godaddy, Network Solutions, and Register.com.  Note that the new and correct IP address for Postalytics is ““.


  • After logging into Godaddy, Click your User ID in the upper right corner.
