Reply IP addresses

If your email account can't connect to Reply, your company's firewall or mail server may be blocking connections from unknown addresses. Add Reply's IP addresses to your allowlist, then connect the email account again.

How to use them

Ask your IT team or email provider to add all of these addresses to the allowlist of your firewall or mail server. The exact steps depend on your provider.
Once they're added, reconnect your email account in Reply if it was connected via Single Click or use "Test" inside the email account settings.

💡 Reply doesn't offer the opposite option: you can't restrict who logs in to Reply or uses your API keys by IP address.
