MillionVerifier has built a solid reputation as a budget-friendly email verification service with more capability than its price suggests. At $0.0039/email for the 10K tier ($39 for 10,000 verifications), it's one of the most affordable options on the market — and pricing drops further at scale ($389 for 1M). But it's not just about price: MillionVerifier claims 99%+ accuracy backed by a 100% money-back guarantee if bounce rates exceed 4%, has a full real-time API with client libraries in 8 languages, and integrates with 17+ ESPs.
If you've got a large email list and need to clean it before a campaign, MillionVerifier is a compelling option. The economics are strong, and the no-charge policy for catch-all results keeps effective costs even lower.
Where MillionVerifier falls short is the sales use case. No email finding, no catch-all resolution (it marks them as risky but can't tell you if a specific address is valid), and limited integrations with sales tools like Clay and CRMs. For marketing list hygiene, it's excellent. For outbound sales where you need to build and verify prospect lists in one workflow, it's only half the equation.
LeadMagic approaches the problem differently. Instead of optimizing for the lowest per-email cost, it optimizes for the lowest cost per usable contact. 99.5% accuracy, catch-all resolution, and combined finding + verification mean you get a verified, deliverable email in one step. The per-credit cost is higher, but you're not paying for a separate finder, not losing contacts to unresolved catch-all domains, and not eating bounces from lower accuracy.
Feature Comparison
MillionVerifier handles verification well: valid, invalid, disposable, role-based detection, with both bulk CSV upload and a full real-time API. The API supports single email verification with client libraries in 8 languages and isn't rate-limited — though response times (2-60 seconds) are slower than LeadMagic's sub-200ms. For most batch and integration use cases, MillionVerifier's API works fine.
Catch-all handling is the biggest gap. MillionVerifier marks catch-all addresses as "risky" and leaves the call to you — though notably, it doesn't charge for catch-all results, which is a fair trade-off. Given that roughly 30% of B2B domains use catch-all configurations, that's still a lot of contacts left in limbo. LeadMagic resolves catch-all emails to valid or invalid, turning "maybe" into "yes" or "no."
The speed difference matters for specific workflows. LeadMagic responds in under 200ms, which is critical for real-time form validation, Clay enrichment workflows, and any use case where you need an instant answer. MillionVerifier's 2-60 second response times work for background verification but aren't ideal for real-time pipelines.
And then there's email finding. MillionVerifier can only verify addresses you already have. LeadMagic finds and verifies in one step. For teams building prospect lists, that's the difference between needing one tool and needing two.
Pricing
MillionVerifier wins on price. At the 10K tier, you're paying $0.0039/email ($39 total). At 1M, it drops to $389 ($0.000389/email). It's a one-time purchase model — buy credits, use them whenever, no subscription required. Credits don't expire. They also don't charge for catch-all results, which further reduces effective cost.
LeadMagic starts at $59.99/mo for 2,500 credits. Email validation uses just 0.25 credits per email — so the Basic plan covers 10,000 validations at $0.006 each. The Essential plan ($99.99/mo for 10,000 credits) covers 40,000 validations at $0.0025 each. Pay-per-result means no charge for lookups that don't return a result. Credits roll over on Essential+ plans. MillionVerifier is still cheaper on a pure per-email verification basis ($0.0039 vs $0.0025-$0.006). But when you add the cost of a separate email finder to MillionVerifier's verification cost, and factor in the 30-40% of enterprise emails that MillionVerifier can't resolve, LeadMagic delivers more usable results per dollar — with catch-all resolution and sub-200ms speed included.
The right choice depends on your workflow. Cleaning an existing list? MillionVerifier is hard to beat. Building a list from scratch? LeadMagic saves you money by combining steps.
