Inactive + disconnected numbers
Disconnected lines and reassigned numbers sit in old CRMs, ad-platform exports, and lead-buy lists. Every send to one of them is wasted spend AND a deliverability ding.
Tells Number Intelligence analyzes carrier data, line type, phone activity, and engagement signals to generate an Activity Score for every number. Identify high-quality contacts, filter out inactive or low-value numbers, and stop spending budget on messages that will never land.
Our 28-second take on what happens when you don't check your list first.
The problem
Lists rot. Numbers recycle. Bots flood signup forms. Inactive, disconnected, and low-quality numbers waste budget the moment a campaign hits send and quietly drag down deliverability scores across your whole program. Number Intelligence catches them before they cost you anything.
Disconnected lines and reassigned numbers sit in old CRMs, ad-platform exports, and lead-buy lists. Every send to one of them is wasted spend AND a deliverability ding.
Click-farm and form-spam traffic come with thousands of low-quality numbers. They eat budget and skew your reporting if you do not screen them at ingestion.
Carriers watch your bad-send ratio. Too many failed deliveries and your throughput cap drops for every campaign that follows, not just the one with the dirty list.
A bare phone number tells you nothing. Carrier, line type, activity indicators, and engagement signals change which numbers your reps and best creative should get first.
Flagship signal
Every phone number gets an Activity Score from carrier data, line type, phone activity indicators, and engagement signals. A higher score means the number appears active and engaged. A lower score means it is less reliable, inactive, or unlikely to respond. Use it to prioritize, filter, route, and protect deliverability all in one signal.
Inactive, disconnected, or repeatedly flagged signals. Do not send. Saves the budget AND the deliverability score.
Active but lower engagement signal. Downgrade to a cheaper sender, keep the volume, optimize cost-per-reach.
High activity, identity-verified, engagement-positive. Send your best creative through the premium route.
The path
The same scoring pipeline we run inside our own high-volume SMS programs, exposed for any list you already own. Most teams pilot with a CSV in a single afternoon.
Upload a CSV, hit the API, or wire it into your CRM through our integrations catalog. Tells Number Intelligence works with whatever you already use.
Each number gets an Activity Score plus carrier, line type, validity, and reachability signals. Sub-100ms per lookup typical, batch-friendly for backfills.
Skip sub-30, downgrade 31 to 70, premium-route 71 to 100. Or define your own bands per campaign. Pipe straight into Tells SMS or write-back into your CRM.
Numbers decay. Run Number Intelligence on existing lists quarterly so a six-month-old "clean" list stays clean instead of quietly sliding to 15 to 20 percent rot.
Where it shows up
Six places running Number Intelligence ahead of the send measurably moves the metric: cost per delivered message, lead quality, response rate, sender reputation, and overall ROI on the list you already paid for.
Score every contact at ingestion or pre-send. Send only to numbers worth reaching. Activity Score tells you which ones are worth the spend before the campaign fires.
Automatically suppress sub-30 Activity Score contacts. Stop paying to message dead lines, recycled numbers, and bot-shaped form submissions.
Same audience, fewer wasted touches. Higher response rate per dollar spent because the budget concentrates on numbers actually likely to respond.
Route high-score leads to your best reps and your best creative. Deprioritize the rest into nurture cadences instead of burning headcount on dead end leads.
Poor-quality data hurts your sender reputation across every campaign. Number Intelligence keeps your scores clean by suppressing the sends that would have dragged them down.
Re-score old lists before re-engaging. A six-month-old "clean" list is usually 15 to 20 percent rotten. Re-scoring is the cheapest lift you can give an existing audience.
Why Tells
Most "validation" tools hand you a score and walk away. Tells runs the same Number Intelligence inside the send path so the routing decision happens automatically. Same signal, same platform, no integration gap to maintain.
The same Activity Score Tells's own routing engine uses to decide what to send and where. Score the number, then send through high-volume SMS or an AI agent on the same stack. No integration gap.
Carrier data, line-type classifications, activity indicators, engagement signals. No scraped data, no opaque aggregators, no audit landmines.
Carrier info, line type (mobile, landline, VoIP, other), validity, disconnect signals, reachability. Actionable insight that drives a routing decision, not just metadata sitting in a column.
Volume pricing that scales with your campaign rhythm. Pilot with a CSV today. Most teams find Number Intelligence costs a fraction of the wasted-send cost it eliminates inside the first campaign.
