A canvass is expensive and high-value: a real person reaches a voter at their door. But the contact usually ends when the canvasser walks away, and reaching that voter again means another door knock. The door-to-text handoff fixes that, capturing a text opt-in at the door turns a one-time field contact into a subscriber you can reach for the rest of the cycle at a fraction of the cost. Here's how it works.
Why capture an opt-in at the door?
Because the door contact is the hard part, and it's wasted if it doesn't persist. Canvassing is the most resource-intensive voter contact there is, so getting a durable opt-in out of it multiplies the return: instead of one conversation, you get a channel to that voter for every future reminder, ask, and GOTV nudge. A canvass that captures opt-ins builds your texting list with exactly the engaged voters you most want on it, so the field program feeds the texting program.
How does the handoff work?
Make the opt-in the natural close of a positive door conversation:
- A canvasser QR code. The walker shows or leaves a QR code the resident scans to subscribe, one tap, on their own phone.
- A keyword or link the canvasser gives verbally or on a leave-behind for the residents who aren't home.
- A clear, honest ask. "Want reminders and updates from the campaign? Scan here", framed as a benefit, not a data grab.
- Capture the consent record as the resident opts in, so it's documented.
Even the empty doors become opportunities: a door hanger with a QR code turns a no-answer into a possible subscriber.
How does it fit the program?
It closes the loop between field and text. The canvass identifies and persuades voters in person; the opt-in captures them into a channel; texting then reinforces, reminds, and turns them out cheaply, and the data the canvasser collected sharpens those texts. This is the door-to-text integration that makes an integrated program more than the sum of its channels: the most expensive contact (the door) seeds the cheapest ongoing one (text), so every canvass pays dividends long after the canvasser goes home.
Frequently asked questions
Why capture a text opt-in during canvassing?
Because the door contact is the expensive, hard part, and it's wasted if it doesn't persist. A text opt-in turns a one-time field conversation into a channel you can reach that voter through cheaply for the rest of the cycle.
How do you capture opt-ins at the door?
With a canvasser QR code the resident scans on their own phone, a keyword or link for a leave-behind, and a clear, honest ask framed as a benefit. Even door hangers on empty doors can carry a QR code.
How does the door-to-text handoff help the program?
It connects field and text: the canvass identifies and persuades in person, the opt-in captures the voter into a channel, and texting reinforces and turns them out cheaply, with the canvasser's data sharpening the messages.
