First 100 full SMTP verifications/month free forever. No credit card required.
Comparing email verification vendors by headline per-credit price alone hides the two biggest drivers of your real annual bill: credit expiration forfeitures and charges on "Unknown" / greylisted results. On a typical 100,000-row B2B list, 8% to 14% of rows are duplicates or corporate gateways (Proofpoint, Mimecast) that temporarily defer initial probes.
When a vendor charges you $400 for 50,000 credits AND burns 6,000 of those credits on inconclusive unknowns and duplicates, your effective cost per usable verification spikes by 15%+. KaijuVerifier combines a $49/month rate for 50,000 checks with $0 client-side deduplication, $0 unknown billing, and automatic monthly credit rollover.
| TCO Cost Component | Legacy Verifiers (ZeroBounce / Kickbox / NeverBounce) | KaijuVerifier Swiss Precision TCO |
|---|---|---|
| 50,000 Monthly Verifications Base Price | $250/mo to $400/mo ($3,000–$4,800/yr) | $49/mo ($588/yr — Save up to 88%) |
| Billing on 12% Unknown / Greylisted Rows | Charged full price (burns 6,000 credits per 50k list) | $0 Charged (100% automatic credit protection) |
| Pre-Upload Duplicate & Syntax Removal | Often billed unless manually cleaned in Excel first | $0 Charged (Instant browser pre-scanner strips duplicates free) |
| Multi-Sheet .XLSX Workbook Preservation | CSV-only (requires manual sheet splitting & merging) | Included Free (Native multi-tab .XLSX upload & export) |
Teams verifying 50,000 emails/month save $4,092/year switching from ZeroBounce ($390/mo vs $49/mo) and $2,412/year switching from NeverBounce or Bouncer ($250/mo vs $49/mo).
Yes. Because 8% to 18% of raw B2B lists consist of duplicates and greylisted unknowns that competitors bill for, KaijuVerifier’s $0 unknown/duplicate policy adds an extra 12%–20% in effective credit savings.
