SMS List Building | Build a Consent-Based Contact List | TextingOnly
Contact Intelligence · List Building · Outbound Automation
The list builds
itself. The
strategy is
built in.

Every opt-in creates a contact record. Every entry point creates a segment. Every interaction appends to the journey. By the time you send the first outbound message, you already know who you’re talking to, where they came from, and what they need to hear.

Scan to qualified lead in under 4 minutes.
See every step in detail →
01
Scan, tap, or click
A QR code, SmartLink, or click-to-text button triggers the flow. Geo-stamp and campaign attribution fire at the moment of scan — before the user takes any further action.
02
One tap creates the contact
The native Messages app opens with the message pre-filled. One tap sends. At that instant: phone number captured, TCPA consent documented, contact record created. No form. No typing.
03
OTTO collects intent data
OTTO runs the qualification flow — ITR menu, data collector, or both. Every answer becomes a structured field in the contact record. Partial completions still capture the phone number.
04
Lead delivered, list updated
Structured lead fires to your team. Contact lands in your segmented list — attributed to campaign, entry point, and intent. Permission to contact stays active until opt-out.

Guide
Zero-Party Data

What carrier-verified, consent-based mobile identity means for your marketing — and why it outperforms every other data type.

Start at zero. Grow on intent.
Your list is already
building itself.

Every scan, every tap, every opt-in creates a contact that belongs to you — verified, attributed, segmented, and ready to be worked. Not a rented audience. Not a cold import. Yours.

Four entry points into the bottom bar
Every path leads to
the same destination: native SMS.

The entry point is where you meet the prospect — in print, online, on their phone, or in a missed moment. The SmartLink is the engine beneath all four. Every entry is geo-stamped, attributed, and OTTO-ready the instant it fires.

Four paths. One destination. Hover any tab to see the user experience live — or tap on mobile.
