There are a few different options for envelopes and outboxes with arrows pointing in different directions:

:email: :incoming_envelope: :outbox_tray: :postbox:

Another route would be something a bit more comical. Since `send` is typically used to invoke `private` methods. I think this one implies “throwing caution to the wind”:

Another thing to consider is how/if we want to represent `public_send` as opposed to send. Maybe I’m taking this too seriously but I’d like to think this all the way through before merging.
