Alternative to QuickEmailVerification on Email Verification

Introduction

QuickEmailVerification is one of the older email verification services, and it shows — both in its established reputation and in where it hasn't kept pace. The claimed accuracy of 95% is noticeably below current industry standards. At 100,000 emails, that 4.9% gap versus BillionVerify's 99.9% means roughly 4,900 more bad addresses making it into your list.

This comparison breaks down where QuickEmailVerification falls short and where BillionVerify is a better fit for teams that care about list quality and cost.

Customer Reviews

Marcus Chen, VP of Marketing at DataDriven Co. Rating: 5/5 "We verified the same 200K list with both services. QuickEmailVerification marked 95% valid — BillionVerify flagged an additional 9,800 addresses as invalid or risky. Those addresses had been hurting our sender reputation for months. After switching and cleaning the list properly, our open rates improved by 18 points."

Elena Vasquez, Email Deliverability Specialist at Agency Scale Rating: 5/5 "The pricing difference is real. We were paying around $400/month for 100K verifications with QuickEmailVerification. BillionVerify charges us $80 for the same volume. That's $3,840 per year back in the budget. The accuracy improvement is also noticeable — fewer bounces on every send."

Tom Bergstrom, Head of Growth at FinTech Startup Rating: 5/5 "QuickEmailVerification's API was a bottleneck in our signup flow. At 800ms we were adding nearly a full second of latency to every registration. BillionVerify's API responds in under 300ms — our forms now feel instant. The six SDK options also meant we could integrate with our Go backend directly instead of through a workaround."

Frequently Asked Questions

What does the 4.9% accuracy gap mean in practice?

At 100,000 emails, QuickEmailVerification's 95% accuracy leaves approximately 4,900 more bad addresses in your verified list compared to BillionVerify at 99.9%. Those addresses bounce, hit spam traps, or go to role accounts — all of which damage your sender reputation with ISPs like Gmail and Outlook. The bulk email verification accuracy gap compounds over time.

Why is BillionVerify so much cheaper at scale?

BillionVerify's pricing structure is designed for volume. At 10K, the effective rate is $0.001/email. By 100K it's $0.0008/email, and by 1M it's $0.00035/email. QuickEmailVerification's dynamic calculator pricing does not scale down as aggressively, which is why the savings at 500K reach approximately $700 per run.

Is QuickEmailVerification's API easier to use?

QuickEmailVerification uses a simple GET request with the email as a query parameter, which is easy to test in a browser. BillionVerify uses a POST with a JSON body, which is standard modern API design. Both are straightforward to integrate. BillionVerify's documentation includes interactive examples and SDKs in 6 languages, which simplifies integration in most tech stacks.

Does BillionVerify detect catch-all domains better than QuickEmailVerification?

BillionVerify tests catch-all domains using multiple probe addresses and risk scoring, achieving about 95% detection accuracy on catch-all configurations. QuickEmailVerification offers basic catch-all detection. The catch-all verifier capability matters because catch-all addresses are often unreliable — some domains accept all mail at the server level but bounce it later.

What about the free trial comparison?

QuickEmailVerification gives 100 credits once. BillionVerify gives 100 free verifications every day, indefinitely. Over a month, that's 3,000 free verifications versus 100. This also means you can use the free tier to test the service continuously without committing.

How does role-based email detection compare?

BillionVerify's role-account detection categorizes addresses into specific types: Generic (info@, contact@), Support (support@, help@), Admin (admin@, webmaster@), and Sales (sales@, business@). This lets you make granular decisions about which roles to exclude. QuickEmailVerification flags role accounts but provides less categorization detail.

Can I import lists from QuickEmailVerification into BillionVerify?

Yes. Export your lists from QuickEmailVerification as CSV and upload them directly to BillionVerify. The upload process takes a few minutes and supports files up to large sizes. We recommend re-verifying any list older than 30 days regardless of the source.

Does BillionVerify support the same upload formats?

BillionVerify supports CSV, Excel (XLSX and XLS), TXT, and JSON. QuickEmailVerification supports CSV and TXT. BillionVerify covers all formats QEV supports plus more.

Conclusion

Verdict: QuickEmailVerification built a reputation as a simple, reliable service in an earlier era of email verification. In 2026, BillionVerify offers meaningfully higher accuracy (99.9% vs 95%), faster processing at 3.3x the speed, API responses 2.7x quicker, and substantially lower pricing at every volume above 10,000 emails. At 100K, BillionVerify is approximately 80% cheaper; at 500K, approximately 78% cheaper. The savings at scale are large enough to be a primary reason to switch, independent of the accuracy and speed advantages.
