Mailinator is known for high-speed receipt of both Email and SMS. But in reality, a message is a message and that includes inbound webhooks from any source (i.e. HTTP POST). Whether you hook up Mailinator to your alert system or a third-party like Zapier or Twilio, you can send anything into your Private Mailinator Inboxes.
From there, it only gets better. Injected messages are then treated like any other message entering the system. The message is stored in your Private Repository and is run through all the Rules you configure.
