IP Allowlist

Do you feel the need to secure API access to your account? Well so do we! Because of this, we've implemented the IP allowlist settings, where you can specify the IPs that have permission to access the API.  When utilizing the IP allowlist, only the IPs you have specified will be able to connect to the API. 

Note: this will not impact SMTP connections.

How to Enable IP Allowlist? 

We'll show you how to do this below:

  1. First, log in to the Mailgun Control Panel (if you have not already done so).
  2. Then, at the top-right corner of the page, click the Profile drop-down menu to expand its list of options.
  3. Next, click the Security option. Alternatively, you can use this direct link
  4. On the resulting page, click the API security tab.
  5. In the IP whitelist section, click the Add to whitelist button. 
  6. Finally, enter the IP / CIDR and click the Save IP address/CIDR button.

That's it - you should be all set! While an important and highly effective way to secure your account, it is actually really quite simple to add and remove IPs from the IP allowlist.
