We currently deliver campaigns from the following IP addresses: • 206.72.127.0/24 • 184.106.87.160/29 • 184.106.87.168/29 • 184.106.86.128/28 If you are finding that certain clients are not receiving their campaigns, you may ask their mail administrator to whitelist these IP’s to ensure the emails are let through. These IP’s may change (or be added to) in the future as we add more delivery servers, and we will keep this page up to date.
