For many comms channels push notifications, email, SMS etc. drop-off recovery is one of the most common campaign use cases and is very easy to automate. You will need a trigger event and a stop event for example, "Order.Started" and 'Order.Complete".
For details on adding events on Mobile and web see docs here:

Once you have a trigger and stop event you are ready to automate a drop off campaign. Open a triggered campaign from the create campaign menu and get your options and content set-up. You can then use the trigger event on the events page like this example below which is an event based on a sign-up start:
In the above example the user is set to get the communication an hour after the trigger event (you can have additional follow on campaigns that go out after 24hrs, 3 days, 5 days etc.).
You then use the stop event that indicates that the user has finished this journey on the segments page to prevent the user from receiving any communication if they did not drop off and went on to complete the journey.
