Technically, any messaging sent through a messaging software platform like RumbleUp is Application-to-person (A2P) messaging. Peer-to-Peer (P2P) messaging involves messages sent one by one by a human operator, even if done through an application. Sometimes the term A2P is used to refer to messaging software platforms in which the messages are sent in bulk to a list without the intervention of a human operator. RumbleUp is an A2P messaging platform that enables campaigns and organizations to send messages individually to end users, which is commonly referred to as P2P messaging.
