Safelisting On The US (North American) Platform

Proofpoint Security Awareness Training uses a variety of systems to communicate to devices within your network and deliver email messages to your end users. This guide documents the IP addresses, domains and URLs used to deliver this information. This document should be provided to your email or security administrators to ensure reliable communications.  


  • Only perform safelisting for your licensed Proofpoint Security Awareness Training products. 
  • Only safelist the IPs and domains for your hosted location.  If you aren’t sure of your hosted location, please contact Customer Support.

Training Notifications

Proofpoint recommends that Training Notifications are sent with a “From:” address that uses your organization’s domain name. This email address will be more familiar to the user and allow the user to easily reply to the message, should they have questions. Before we can send emails using your domain name, you must contact your mail administrator as most email systems restrict email using your organization’s domain name to authorized mail servers. To allow email from our servers using your organization’s domain name, we recommend asking your email administrator to make the following changes: 

  • Add the appropriate IP addresses to your SPF records and your email filter safelist 
  • is a domain that can also be safelisted for web filtering
