When B2B outbound teams and SaaS developers look beyond legacy providers like ZeroBounce and NeverBounce, three mid-market email verification platforms frequently top the shortlist: Bouncer (usebouncer.com), Kickbox, and Clearout. While all three offer solid REST APIs, their pay-as-you-go (PAYG) credit rates still charge $400 to $500 per 100,000 verifications—nearly 7x to 8.5x more than MailVeri ($59 per 100,000 non-expiring credits).
Verified 2026–2027 Pay-As-You-Go Rate Card Comparison
| Provider | 10,000 Credits | 100,000 Credits | 1,000,000 Credits | Credit Expiration |
|---|---|---|---|---|
| MailVeri | $9 ($0.0009/check) | $59 ($0.00059/check) | $299 ($0.0003/check) | Never Expire (Lifetime) |
| Bouncer (usebouncer.com) | $64 | $400 | $2,000 | Never Expire |
| Kickbox | $70 | $500 | $2,999 | 12 Months |
| Clearout | $65 | $400 | $1,400 | Never Expire (PAYG) |
Where Bouncer, Kickbox & Clearout Cost You Extra
- Kickbox's $500 per 100K Tier & 12-Month Credit Expiry: Following Kickbox's acquisition by PerformLine, verifying 100,000 contacts costs $500 ($0.005/email), and unused PAYG credits expire after 12 months. MailVeri verifies the same 100,000 contacts for $59 (an 88% savings) with credits that never expire.
- Bouncer's 6.7x Price Premium at Scale: Bouncer is well-regarded in Europe for GDPR compliance, but charges $400 for 100K checks and $2,000 for 1M checks—compared to $59 for 100K and $299 for 1M on MailVeri.
- Clearout's Mid-2026 Rate Hike (+27% at 1M): Clearout raised its PAYG rates from $58 / $350 / $1,100 to $65 / $400 / $1,400, making high-volume waterfall enrichment in Clay or n8n nearly 5x more expensive than MailVeri.
7-Status Verification Precision & 5-Minute API Migration
Beyond saving 85% to 90% on Pay-As-You-Go verification credits, switching from Bouncer, Kickbox, or Clearout to MailVeri gives your engineering and growth teams deterministic 7-status classification (VALID, INVALID, DISPOSABLE, ROLE_ACCOUNT, CATCH_ALL, FULL_INBOX, and UNKNOWN), direct 1,000,000-row CSV/Excel batch uploads, signed MailVeri/2.0 completion webhooks, and native Model Context Protocol (MCP) tools for Claude Code and Cursor.
Migrating an existing Kickbox, Bouncer, or Clearout HTTP call takes under 5 minutes by pointing your request to MailVeri's REST endpoint—with 0 credits deducted whenever a target mail server returns an inconclusive UNKNOWN deferral:
