In practice
It runs through an API call from a form or app and returns a result within the time a person will wait. It stops bad addresses at the door, while batch verification cleans a list that already exists.
Verification and sending
ValidReach offers a real-time API for single addresses and file upload for lists. Use the first at capture and the second for older data.
