Cold outreach teams

Stop wasting dials on dead lines. Know which numbers are live mobile phones before your sales team picks up the phone.

Maintain Caller ID reputation
Network analytics flag repetitive calls to disconnected numbers as suspicious. Keep your outbound lines clean to avoid 'Spam Likely' tags.
Actionable data segmentation
Distinguish between mobile, landline, and VOIP. Route mobile leads to SMS and call sequences and deprioritize fixed lines for automated outbound.
Increase connect rates
Focus your team's energy on verified reachable numbers. Higher connect rates directly correlate to better quota attainment and morale.

The workflow

1

Export your leads

Pull your target lists from Apollo, ZoomInfo, or your custom scrapers and upload the raw CSV directly to Numtrue.

2

Filter the noise

We ping the networks to verify reachability. You instantly see which numbers are live mobiles and which ones are dead.

3

Dial with confidence

Import the clean data back into Outreach or SalesLoft. Your reps only call live numbers, keeping morale high and pipelines full.

Your SDRs are paid to close deals, not audit phone numbers.

Every minute your sales reps spend listening to carrier intercept messages is pipeline lost. Protect your outbound Caller IDs and keep your team motivated by feeding them lists that actually ring.
