Automatically stop the campaign after prospect's reply

When prospects make an inquiry online, you reach out to them and they don't answer. You put them on a campaign for example "initial contact attempt" telling them you have been trying to reach them till certain number of attempts, etc... I'd love to see a feature of having the campaign stop/be completed after the client replies to that email or text. This is specially helpful when agents are not by the computer to manually remove/stop/complete the task from that prospect.
