IP Address White Listing

White listing allows you to mark email addresses or IP addresses as trustworthy. Most companies have a firewall that blocks bulk mail. White listing allows mail to bypass firewalls, spam filters and blacklists, allowing emails to be delivered to the inbox without being filtered into spam.

Internal email servers treat the same email sent to multiple recipients in the same domain as suspicious. The email firewall will block these emails. To ensure all internal mails are delivered to internal recipients, your mail security team / IT department will have to white list our email sending servers.

This is a list of our IP ranges:

  • 69.63.146.128/26
  • 69.63.158.32/28
  • 68.169.14.0/24
Do note, these are IP address pools and not single IP addresses.
