Recruiting lead verification
Recruiting firms sit on some of the largest and most frequently updated contact databases in any service industry — candidate pipelines, hiring manager networks, and alumni placements built over years inside ATS platforms like Bullhorn, Greenhouse, or Lever. The problem is that candidate email addresses shift with every job change, and a mobile number captured during a 2022 placement may belong to an entirely different person today. Sourcing efficiency falls sharply when a meaningful portion of outreach never reaches its intended recipient.
What's hiding in your list
Candidate records in an ATS are typically enriched at the point of application or sourcing and then rarely updated, so a pipeline built from LinkedIn exports and resume submissions accumulates stale work email addresses with every passing quarter.
Hiring manager contacts captured during a client engagement become unreliable as soon as that contact changes roles or companies, turning a warm relationship into a dead deliverable.
Contractor and gig-worker pools maintained for high-volume placements often contain personal Gmail or Yahoo addresses that candidates cycle through or abandon as their working status changes.

Frequently asked
How do we validate the candidate data we export from Bullhorn before a reactivation campaign?
Export your candidate segment as a CSV and run it through BounceBlock — email verification, phone validation, and duplicate removal happen simultaneously. You get a scored file back with each record rated 0 to 100, so recruiters can prioritize high-confidence contacts for immediate outreach and deprioritize uncertain records rather than wasting a touch on a dead inbox.
We source passive candidates from LinkedIn. Are those emails worth verifying?
Absolutely. Passive candidates listed on LinkedIn often have corporate emails that change the moment they leave a role, and personal emails from data enrichment tools are notoriously inconsistent. Verifying at the mailbox level before sequencing those contacts prevents hard bounces that damage your sending domain reputation — a real operational risk for agencies running large outreach volumes.
Our firm places candidates across multiple verticals. Is flat-rate pricing practical for us?
Flat monthly pricing is exactly what makes BounceBlock practical for recruiting firms that process varying volumes each month. You are not charged per verification, so you can clean a 10,000-record passive candidate list one month and a targeted 500-record hiring-manager list the next without recalculating budget. Start with the free 100-row preview at /signup to validate the output format before your first full run.
