If your organization uses its domain to send and receive an email, we recommend providing the following IP address range to your domain administrator. Adding these IP addresses to your list of safe senders will ensure your Firewall or Spam Filter does not block email notifications sent through the AppointmentPlus system. This process is also known as Whitelisting.

Please Whitelist the Following IP Address Range: 

• 136.179.33.60
• 146.20.112.24
• 146.20.191.140
• 166.78.71.221
• 216.117.222.0/24
