When QuickEmailVerification is the better pick

QuickEmailVerification (QEV) is an established brand in the developer community with a proven API, extensive documentation, and SDKs across multiple languages. Their weekly subscription model ($99/wk for 50 000) can suit burst workloads where you need a concentrated volume in a short window. QEV's long track record and developer-focused resources make it a safe, well-known choice for engineering teams.

When emailzeno is the better pick

emailzeno offers significantly better ongoing value. Our Growth plan ($29, 25 000 verifications) replaces a $40 pay-go spend. Unlimited ($39) has no volume ceiling — their equivalent burst pricing is $99/week for 50 000. EU hosting is default, not a DPA negotiation. Auto-credit on hard bounces directly reduces effective cost. For any recurring or high-volume workflow, emailzeno is the more economical choice with equivalent API capability.

Moving from QuickEmailVerification?

Export your verified CSV lists, filter invalid rows, and import to our Suppression Manager. SDK migration: replace the base URL and API key — the REST conventions are nearly identical.

Frequently asked questions

Our single-email endpoint returns in a median 240 ms. Bulk throughput depends on plan tier — Scale plan supports concurrent workers. Both services offer real-time and batch modes.

QEV: ~$0.004/email = $400. Our Unlimited plan: $39 (or $79 Scale for dedicated concurrency). That's a 10×+ cost difference at this volume. The savings grow with scale.

No. QEV credits expire after one year, and they don't offer per-hard-bounce refunds. We auto-credit your account when an address we verified triggers a confirmed hard bounce — our Unlimited plan effectively means you never pay twice for the same address.
