# IP Restrictions for Tokens

> Lock a sending token to specific IP addresses so only trusted servers can use it.

Add a list of allowed IP addresses to any token you use to send emails. Requests from anywhere else are rejected, even if someone gets hold of the token. Perfect for locking a token to your production servers, so a leaked key can't be used from an unknown machine.

**Status:** Done
**Completed:** Jul 2026
