Data Quality Standards
Know your data quality before you spend a dollar.
Deliverability, phone type, DNC risk, freshness — every field matters. We verify before you buy so your team connects, not bounces.
"Bad data costs more than no data. Every unverified phone number is a wasted dial, a compliance risk, or a lost hour."
The Quality Engine: 6 layers of verification
Every lead passes through a multi-step pipeline before it reaches your download.
Sourcing
Multi-source data collection
Every record originates from opt-in directories, public business registrations, or licensed data partnerships. No scraped, non-consented, or purchased personal data.
SOURCES VERIFIED:
Verification
Multi-step verification
Email addresses pass syntax, domain, and mailbox-level checks. Catch-all detection and spam-trap identification flag risky addresses before they reach your list.

Phone Type
Mobile vs. landline classification
Real-time carrier lookups classify every number as mobile, landline, or VoIP. Connect rates for mobile numbers are typically 3–5× higher than landline.
📱 3–5× higher connect rate on mobile
DNC / Compliance
Registry screening
Numbers are screened against Federal and all 50 state DNC registries, plus TCPA litigator databases. Updated daily to match the FTC's refresh schedule.
Freshness
Daily database refresh
Contact data degrades over time. Our database is refreshed daily with new records and updated information, so you're working with current data.

Limitations — what verification does not guarantee
- Typical results show 95%+ email deliverability — not 100%; some addresses may still bounce.
- Contact information changes daily — even verified data can become stale over time.
- DNC compliance is point-in-time — consumers can register after your download.
- Cannot verify purchase intent or sales readiness — only contact accuracy.
- Match rates depend on input data quality and available identifiers.
Start with data you can trust.
- Real-time verification
- DNC + litigator scrubbing
