Now it's on @gmittal to actually test things 😉

One thing to consider is how to test functions such as sending an SMS/email (because that has a tendency to break silently).

Sending an SMS from the Twilio number to itself should work. It'll test both the sending functionality (which Twilio will complain about if something is configured poorly) and the receiving handler (which mailroom will complain about as well).

Proof you can SMS yourself (we already knew you could email yourself):

After the Twilio incident (#75) finally taking a look at this again.
