Direct mail teams running postcard and letter campaigns need to know the moment someone actually engages with a piece that landed in a mailbox days ago, rather than waiting on reply rates that trickle in over weeks. HomeDrop tracks that moment with its Tracking Link Opened trigger, firing whenever a recipient scans a QR code or visits the link printed on their mail, alongside actions like Add Recipient to Open Campaign, Add to Nearest Neighbor Campaign and Send Mail (No Campaign).

Through Zapier, a scanned tracking link can prompt Mobile Message to text that person straight away, while a reply on the SMS side can add their address to HomeDrop's do-not-mail list. A prospect who scans a postcard and gets a text within minutes is far more likely to respond than one who waits for the next mail drop, and a customer who opts out by text stops receiving paper as well as messages. A campaign manager running several mail drops at once gets a live signal instead of guessing which piece actually landed with someone.
