Client churn starts with bad data. BounceZero verifies every email address before delivery - so your clients' campaigns land, your reputation holds, and your contracts renew.
100 free verifications every month - No credit card required
You can source the perfect ICP, write flawless copy, and build a beautiful sequence - but if the emails bounce, the client blames you. Email verification for lead generation agencies isn't optional. It's your retention strategy.
Email data decays at ~22% per year. Scraped and purchased lists are worse. When your delivered leads bounce, the client's sender reputation tanks - and your invoice gets questioned.
Around 23% of B2B domains are catch-all - they accept every email, then silently drop the bad ones. Most verifiers mark these "unknown". BounceZero's 3-probe catch-all analysis resolves them.
Clients renew when you show hard numbers. Delivering lists verified to 99.8% accuracy with sub-0.5% bounce rates gives you a deliverability guarantee competitors can't match.
Before a single email lands in your client deliverable, BounceZero validates it against every signal that predicts a bounce, a spam trap, or a wasted send.
SMTP-level confirmation that the inbox actually exists and accepts mail - before your client ever sends to it.
Triple-probe analysis resolves catch-all domains that other tools dump into "unknown", turning risky leads into scored ones.
Flags info@, sales@, and support@ addresses that inflate lead counts but rarely convert - and often trigger complaints.
Catches throwaway and temporary addresses from form-fill spam so they never reach a client deliverable.
Confirms the domain has live, correctly configured mail servers - dead domains are filtered out instantly.
Identifies known and suspected spam traps that can blacklist your client's sending domain from a single send.
Slot BounceZero between your data sourcing and client delivery. Most agencies verify a 10K-lead list in 5-10 minutes.
Pull your raw list from Apollo, Clay, LinkedIn scrapers, or your enrichment stack - CSV in whatever shape it comes.
Drag and drop up to 500K emails per batch. Column mapping is automatic; duplicates are deduplicated for free.
All 6 checks run on every address - mailbox, catch-all, role, disposable, MX, and spam trap. A 10K list finishes in 5-10 minutes.
Download deliverable, risky, and undeliverable segments separately. Ship only the verified segment - keep risky leads for manual review.
Attach the verification report to your client deliverable. A documented sub-0.5% expected bounce rate is a renewal argument in itself.
Wire the 340ms API into your Clay tables, n8n, or Zapier flows so every lead is verified the moment it's sourced - zero manual steps.
At $3 per 1,000 verifications, cleaning a 10,000-lead deliverable costs $30. One saved client relationship pays for years of verification.
Everything agencies ask before adding verification to their delivery pipeline.
Because your product is data quality. Email lists decay at roughly 22% per year, and scraped or enriched lists routinely contain 10-30% undeliverable addresses. Verifying every email before delivery keeps client bounce rates under 0.5%, protects their sender reputation, and directly drives retainer renewals.
Around 23% of B2B domains are catch-all, meaning they accept mail for any address. Most verifiers mark these "unknown" and leave you guessing. BounceZero runs a 3-probe catch-all analysis that scores deliverability confidence for each address, so you can make an informed call on every lead instead of discarding a quarter of your list.
Bulk uploads of 10,000 emails typically complete in 5-10 minutes, and batches scale up to 500,000 emails. For real-time workflows, the API averages 340ms per verification - fast enough to verify leads inline as your Clay, n8n, or Zapier pipeline sources them.
Pricing is $3 per 1,000 verifications, with volume discounts on bulk plans. A 10,000-lead client deliverable costs about $30 to verify - a rounding error against the value of the retainer it protects. You also get 100 free verifications every month with no credit card required.
Yes. Agencies typically run one BounceZero account with per-client bulk jobs, or wire the API into their sourcing stack so every lead is verified automatically at capture. Results export as segmented CSVs (deliverable / risky / undeliverable) that drop straight into your client deliverables.
BounceZero verifies at 99.8% accuracy versus an industry benchmark of roughly 95%. Every address passes six checks - mailbox existence, 3-probe catch-all analysis, role account detection, disposable detection, MX validation, and spam trap screening - so the lists you deliver hold up when clients actually send.
99.8% accuracy. $3 per 1,000 verifications. Results in seconds. Start with 100 free verifications - no credit card required.
