Let agents run your Lob campaigns end-to-end

QX shortens links, builds tracked QR codes, verifies recipient identities and watches campaign performance—so your team ships direct mail that actually converts, without the operational drag.

@QX How's last week's postcard campaign performing?

The Q4 reactivation drop is at a 12.4% scan rate—well above your 8% benchmark. The 'winback-vip' QR code is driving 68% of it. Want me to spin up a follow-up to the non-scanners?

Lob

HubSpot

Stop juggling link shorteners, QR codes, address checks and campaign reports. Hand it to an agent.

Campaigns

Launch direct mail without the setup

An agent spins up branded short links, generates trackable QR codes, and wires them into each campaign—so your team ships mail drops in minutes instead of coordinating across three tools.

Tracking

Always know what's working

QX pulls scan analytics, segments responders from no-shows, and surfaces which creative is converting—so you stop guessing and start doubling down on the variants that earn real attention.

Data quality

Mail that actually reaches the right person

Before anything ships, an agent runs identity checks against your recipient list, flags mismatches, and cleans the file—cutting return-to-sender waste and protecting your campaign budget.
