Send to thousands. Read like one. Dynamic keywords pull each contact’s name, location, service type, timeline, and last interaction into your message at send time. OTTO intercepts every reply automatically — routing hot contacts to your team, cold contacts to nurture, and opt-outs to instant compliance. Bulk reach. Personal feel. No manual follow-up.
Dynamic keywords are placeholder fields in your message that are replaced with contact-specific data at the moment of send. You write the template once. TextingOnly fills in the details from each contact’s record — pulling name, city, service type, last interaction, declared interest, or any field you’ve captured — before the message leaves the platform. The result reads as individually written even when you send to ten thousand contacts at once.
Select the contacts from your opted-in list — full list, a segment by service type, a geo filter by zip code, or contacts tagged by a prior OTTO interaction. Write your message template with dynamic keyword placeholders. Map each keyword to a field in the contact record. Preview the personalized output for a sample contact before sending. Schedule the send or trigger immediately.
Segment by tag, service, geo, or prior interaction · Preview before send · Schedule or immediateTextingOnly renders each contact’s personalized version at send time and dispatches from your dedicated 10DLC-registered number. Carrier throughput is managed automatically — large sends are paced to comply with carrier requirements without manual rate management on your side. Every message is sent from the same number your contacts already recognize from prior OTTO interactions.
10DLC registered · Dedicated sending number · Carrier-paced · MMS capableEvery reply — YES, NO, STOP, a question, a custom keyword — hits OTTO first. YES or positive reply triggers the ITR qualification flow, Prepare Caller message, and lead alert to your team. NO triggers a graceful opt-down with a follow-up sequence at a longer interval. STOP triggers immediate compliant opt-out. Questions trigger OTTO’s response library. No reply triggers a timed follow-up sequence. Not a single contact falls through the cracks.
YES → Prepare Caller + alert · NO → opt-down + nurture · STOP → instant opt-out · Silence → follow-upFirst name, last name, company name. The simplest personalization — “Hi Sarah” vs “Hi there” — increases open-to-reply rates measurably. Already captured at opt-in for every contact in your list.
City, zip code, neighborhood, service area. “We’re running a special in Towson this week” outperforms “We’re running a special in your area.” Geo precision signals relevance at a glance.
What OTTO captured during their original opt-in — HVAC, roofing, new vehicle, kitchen remodel. The message references their specific interest, not a generic category. Converts dramatically better.
“It’s been 6 months since your estimate” or “Your last service was in March.” Acknowledging the relationship history positions your message as a follow-up, not a cold blast. Changes the psychology of the open.
Tags applied during prior OTTO interactions — “interested in financing,” “owns not rents,” “timeline under 3 months.” Segments get different message angles based on declared intent. One list, multiple campaigns running simultaneously.
Any field you configure in the contact record. Vehicle year and model, property type, insurance carrier, preferred language. The more OTTO captures at opt-in, the richer the personalization available for every future send.
Mass texting is only legal to opted-in contacts. TextingOnly is a 10DLC-registered platform — every message goes out through your registered brand and campaign, which carriers and the CTIA require for any business SMS program. Every contact in your list needs a documented SMS opt-in: a specific timestamp, the channel through which they opted in, and the message that was pre-filled when they consented. TextingOnly’s inbound entry points (QR codes, SmartLinks, keyword flows) capture and store this documentation automatically at every opt-in.
Required by all major US carriers for business SMS. TextingOnly handles registration for your brand and campaign — you don’t manage this directly. 10DLC registration →
Every contact who opts in through a TextingOnly entry point has a documented consent record — timestamp, method, message content. STOP is honored immediately and logged. Audit-ready at all times.
STOP triggers immediate opt-out, logged with timestamp. The contact is removed from all active sequences and excluded from future sends automatically. No manual list management required.
