Which IP addresses are used for sending webhooks?

If you send your parsed email data via webhooks to your own server you can add an extra layer of security by white-listing only certain IP addresses. The webhooks issued by mailparser.io are sent from one of the following IP addresses: 


Please note: The IP addresses listed above are used by our worker nodes. However, when you are testing the webhook integration with our app, requests are sent from the app server you are currently connected to. That said, these IP addresses are constantly changing as we scale up our service, and as a result we do not recommend locking down your API to the above source IPs. If you must, the recommended way is to set up and test your webhook with an open firewall. Once, everything works as expected you can close the firewall to the listed IP addresses.
