Special Tags (Mail Tags) [_remote_ip]

Is it possible to hook into the mail / special tags? For instance, I would like to get the IP address of the person submitting the form.

I am using pure JSON method (POST).

Thank you for such a great plugin! I’m sure you can make a PRO version that makes it easy for non-devs to add authorization headers and such.
