IP Addresses that I should whitelist?

If you are finding that certain clients are not receiving their campaigns, you may ask their mail network administrator to whitelist these IP’s to ensure the emails are let through.

We currently deliver email campaigns from the following IP addresses ranges:

  • 27.126.144.0/21
  • 103.28.40.0/22
  • 180.189.136.0/22
  • 184.106.86.128/28
  • 184.106.87.160/29
  • 184.106.87.168/29
  • 203.55.21.0/24
  • 204.75.142.0/24
  • 205.166.177.0/24
  • 206.72.127.0/24

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.
