Methodology
Triple-Verification: Every Record, Every Time
Layer 1
Email Ping Verification
Every email address is verified using SMTP handshake verification (mail server ping) before delivery. We check MX record existence, mailbox existence, and catch-all flag. Temporary and disposable email domains are automatically suppressed.
Accuracy
99.1% deliverability
Method
SMTP + MX lookup
Layer 2
Phone Carrier Lookup
Every phone number is verified via real-time carrier lookup (HLR query). We confirm: number is active, carrier assignment, line type (mobile vs. landline vs. VoIP), and porting status. Disconnected numbers are suppressed from delivery.
Accuracy
97.8% connected rate
Method
HLR carrier query
Layer 3
USPS CASS Address Validation
Every mailing address is validated against the USPS CASS (Coding Accuracy Support System) database. We standardize the address format, verify ZIP+4 accuracy, and flag addresses that are vacant, commercial-only, or P.O. boxes.

Freshness & SLA
Freshness Guarantee & Error Correction SLA
30-Day Re-Verification Cycle
All contact records in the LiveLeadz database are re-verified every 30 days. Records that fail re-verification are suppressed from delivery until they pass a fresh verification check.
Error Correction: 72-Hour SLA
Valid accuracy disputes are acknowledged within 24 hours, investigated within 48 hours, and resolved (replacement or credit) within 72 hours.
Monthly 5% Audit
Each month, a random 5% sample of all delivered records is independently re-tested against live email, phone, and address verification endpoints to confirm the 98% accuracy benchmark.
Source Data Audits
Data sources that generate above-average dispute rates are flagged and undergo a full quality audit. Sources that fail the audit are removed from the delivery pool.
FAQ
Data Accuracy Questions
How is the 98% accuracy claim measured?
The 98% figure represents the average deliverability rate across all three data fields (email, phone, address) on a rolling 90-day audit of delivered lead records. We test a random 5% sample of all delivered records monthly against live verification endpoints.
What happens if I receive an inaccurate record?
Submit a data quality dispute through your LiveLeadz account. We investigate within 48 hours. Verified inaccurate records are replaced at no charge under our Error Correction SLA. Patterns of systematic errors trigger an immediate data source audit.
How fresh is the contact data?
LiveLeadz re-verifies all contact records on a 30-day cycle. Any record older than 30 days that fails re-verification is suppressed from the delivery queue until it passes fresh verification. You receive only currently-verified contacts.
What is the Error Correction SLA?
For valid accuracy disputes: acknowledgment within 24 hours, investigation within 48 hours, replacement or credit issued within 72 hours. Enterprise accounts on monthly or annual plans have dedicated account support.
Do you verify B2B work emails differently from consumer emails?
Yes. Work email verification includes domain MX record validation, catch-all detection, and an additional API check against our B2B email database to confirm the individual is still associated with that company domain.
