Data Verification Service
Don't trust data you haven't verified. Our verification service confirms email deliverability, phone accuracy, and current employment on your existing contacts.
Data verification is a quality check on your existing data. We test every record and provide a confidence score so you know exactly which contacts are campaign-ready.

Scope
What's included in the deliverable
- SMTP-level email validation on every record
- Catch-all detection per domain, flagged on the record
- Phone line-type verification (mobile / desk / VoIP / fax / ported)
- Current-employment confirmation against LinkedIn + company website
- Per-record confidence score (Verified / Risk / Failed)
- Documentation per record for compliance audits
Method
How we deliver it
Send us the records you need verified. Each one runs through the full 5-step pipeline (see our methodology post). The deliverable is a CSV with each input row tagged: Verified, Risk (catch-all or single-source positive), or Failed (likely a bad record). Failed records get a brief reason — bounced, employment-stale, line-type mismatch — so you can decide whether to re-research or remove.
Sample output
What the deliverable looks like
Original input + three appended columns: verification_status (Verified / Risk / Failed), verification_reason (free-text explanation), verified_date (ISO date). A summary report at the end of the deliverable tallies pass/fail by source if you tagged the input rows by data source.
Pricing example
What it costs in practice
A 10,000-record verification pass ships in 2–4 business days. Per-record cost is significantly lower than fresh list-building because the sourcing has already been done; we only run the verification stack.
A go-to-market team was about to run a 30,000-contact campaign off a vendor list. We verified the list as a pre-flight check — found 22% of records were employment-stale and 8% had bad emails. They paused, re-ordered the failing records, and ran a clean campaign with 4% bounce rate instead of the projected 15%.
Boundaries
What we won't do
Honest scope. We'd rather pass on a project than deliver something we can't stand behind.
- Mark a Risk record as Verified to inflate accuracy.
- Verify records sourced from non-business contexts (consumer breach data, etc.).
- Skip catch-all detection because the SMTP probe came back positive.
More FAQs
Additional questions about this service
Should I verify before every send or once a quarter?
For active campaign lists: re-verify within 7 days of send. For static CRM data: once a quarter is reasonable for emails, once every six months for titles. Job-changes are the leakage source — most of the staleness comes from people moving roles.
What happens to records that fail verification?
They stay in the deliverable, tagged Failed with a reason. You decide: drop them, send them to us for re-research, or keep them in your CRM with an inactive flag. We do not silently delete records.
