``` Note: This feature works the same across all Freshservice products. Some screenshots or articles may reflect older designs, but the functionality remains unchanged. If certain options do not appear in your account, they may not be included in your current plan. ```

This article describes how to allowlist specific IP addresses and domains to ensure smooth email delivery from your Freshservice helpdesk, especially if your network setup includes firewalls or restrictions. If your data center is in the US, use the IP addresses and domains below.

Types of mail server

Freshservice offers two options for sending emails:

  • Default (Freshservice/FSBT) \- If your Freshservice/FSBT helpdesk is set up to send emails directly from Freshservice (without additional configurations), you are using the default mail server.
  • Use your own mail server \- If you have configured Freshservice/FSBT to send emails through your organization's mail server (e.g., a server with custom settings or company-specific domains), you are using a custom mail server.

    • IP addresses for your cu stommail server

    If you use a custom mail server to send emails through Freshservice/FSBT, allowlist the following IP addresses in your mail settings to enable Freshservice/FSBT to access, authenticate, and send emails without interruption.

    34.199.167.230
    34.198.193.174
    34.202.174.188
    52.203.5.138
