When is Swiping Intuitive?

What sort of operations make sense with swipe gestures? For dating apps, swiping left and right make sense because the context of the operation is sorting. Some go left, others go right. Goats and sheep etc.

Our app is a game, and it's possible to send messages to other users. There would be a send message screen. If the background of the screen has a mailbox on the right, and a garbage bin on the left, then swiping left and right can be used as the user input for "send the message" and "cancel message" respectively. However, does that make sense?
