It has been around since the early 2010s and built its reputation on straightforward PAYG pricing and simple bulk verification. If you are evaluating it against BillionVerify, this comparison covers accuracy, API performance, pricing at each volume tier, support quality, and integration depth — with real numbers, not marketing claims.

API Performance

Our email validation API is designed for production workloads where latency matters:

A 500ms API response versus a 300ms one does not sound significant in isolation, but at 100 requests/second in a real-time signup flow, that 200ms gap affects user experience noticeably. BillionVerify's higher rate limit also means less throttling under load.

Integration Ecosystem

MillionVerifier covers the essentials. BillionVerify has a broader native integration library, which reduces the amount of custom glue code teams need to write.

Customer Reviews

Alex Romero, Growth Engineer at SaaSFoundry ⭐⭐⭐⭐⭐ (5/5) "We tested BillionVerify and MillionVerifier in parallel on the same list of 50,000 emails. BillionVerify caught 8% more invalid addresses. At scale that is a meaningful deliverability difference. The API latency was also noticeably lower, which mattered for our real-time form validation."

Priya Nair, Email Operations Lead at DataPulse ⭐⭐⭐⭐⭐ (5/5) "The 100 free verifications per day means our team can test before committing credits. MillionVerifier's one-time 50 check limit was not enough to properly evaluate the service. That daily free quota is something we use regularly for spot-checking lists before campaigns."

James Whitfield, Marketing Automation Manager at Revion Media ⭐⭐⭐⭐⭐ (5/5) "Support was the deciding factor for us. We had a billing question on a Saturday evening and got a response within 20 minutes through BillionVerify's live chat. With MillionVerifier's email-only support we were waiting two days for an answer that turned out to be straightforward."

Frequently Asked Questions

How does BillionVerify's accuracy compare to MillionVerifier's in practice?

BillionVerify achieves 99.9% accuracy consistently across list types — transactional, marketing, and cold outreach. MillionVerifier claims 99.5%, but independent user reports in email marketing forums suggest accuracy varies at high volumes, particularly with catch-all domains. Our multi-layer SMTP verification and ML-powered disposable detection catch emails that static database checks miss.

MillionVerifier claims 250K/hour processing speed. Why is BillionVerify's 50K/hour sufficient?

Most email list verification use cases do not require 250K/hour throughput. A list of 100,000 emails completes in 2 hours at 50K/hour — the same day. For the rare use case requiring faster batch processing, BillionVerify supports prioritized queue options. The speed metric that matters more for most teams is API response time, where BillionVerify is 40% faster.

What does BillionVerify do with catch-all domains?

BillionVerify's catch-all verifier tests catch-all domains with multiple probe addresses and applies pattern recognition to estimate delivery probability. Addresses at catch-all domains are flagged with a risk score so you can decide whether to include or exclude them. This is more nuanced than a simple "accept-all" flag.

Are MillionVerifier's credits flexible like BillionVerify's?

MillionVerifier credits expire after 12 months. BillionVerify credits never expire, which matters for teams that verify large lists a few times per year rather than continuously. Expiring credits create pressure to use them and can result in wasted spend.

Can I test BillionVerify without entering payment information?

Yes. You get 100 free verifications every day with no credit card required. This is a genuine ongoing quota, not a trial period. You can use these to test accuracy, evaluate the API, and run small lists indefinitely.

How does role-account detection work?

BillionVerify's role-account detection identifies addresses tied to functions rather than people — info@, support@, admin@, sales@, finance@, and dozens of others. Sending to these increases spam complaints and rarely converts. We categorize them so you can filter them out of marketing sends while keeping them for transactional messages if appropriate.

What support does BillionVerify offer during migration?

24/7 live support covers the migration period. If you run into an API integration issue at 2am, someone is available. We also provide a migration guide, code examples in six languages, and can schedule a technical call for complex integrations.

Does BillionVerify verify emails in real-time during user registration?

Yes. The API is built for real-time inline validation. At under 300ms average response, it fits within the acceptable UX threshold for form feedback. You can validate on blur or on submit and return a result before the form is submitted. MillionVerifier's ~500ms response is on the edge of acceptable for this use case.

Conclusion

Verdict: BillionVerify is cheaper than MillionVerifier at every volume — 75% cheaper at 5K ($5 vs $20), 73% cheaper at 10K ($10 vs $37), 29% cheaper at 50K ($45 vs $63), 38% cheaper at 100K ($80 vs $129), and 50% cheaper at 500K ($200 vs $399). Combined with higher accuracy, 40% faster API responses, 24/7 support, daily free credits, and non-expiring purchases, BillionVerify is the stronger product at all volume levels.
