Processing Methods Compared
Understanding the difference between file processing and real-time API validation
MillionVerifier: File Processing
MillionVerifier focuses on bulk file uploads and processing. Great for cleaning large lists but requires file management and doesn't offer real-time validation.
1Lookup: Real-time + Bulk
1Lookup offers both instant real-time validation and efficient bulk processing through modern APIs. Perfect for form validation and automated workflows.

MillionVerifier vs 1Lookup FAQ
Common questions about MillionVerifier and switching to 1Lookup
What is MillionVerifier?
MillionVerifier is a bulk email verification service that cleans email lists by removing invalid, risky, duplicate, and undeliverable addresses before you send. It is built around uploading a list and downloading verified results, with an emphasis on high accuracy and low cost at large volumes. It also offers an API and integrations for teams that want to verify addresses programmatically. Its focus is specifically email, not phone numbers or IP data.
How much does MillionVerifier cost?
MillionVerifier uses a pay-as-you-go, credit-based model rather than a monthly subscription, and purchased credits do not expire. You buy a pack of verifications and draw them down over time, with the per-verification rate dropping as volume increases. As of publication, entry-level credit packs start around $37 for 10,000 verifications, and an API is available for teams that want to verify programmatically. Always check MillionVerifier’s site for current pricing, since rates can change.
What is the best MillionVerifier alternative?
The best alternative depends on what you actually need to verify. If email list hygiene is your only goal, MillionVerifier is a strong, low-cost option; if you also need to validate phone numbers and IP addresses, 1Lookup is a natural alternative because it handles phone, email, and IP through one API. 1Lookup also offers real-time validation and a 7-day free trial, so you can test it against your own data before committing.
How is 1Lookup different from MillionVerifier?
MillionVerifier is focused specifically on email list verification, while 1Lookup is a broader data-verification API that validates phone numbers, emails, and IP addresses through a single API and one universal credit system. 1Lookup also provides carrier and HLR lookup, reverse lookup, and fraud and IP intelligence, with data updated daily from FCC and carrier sources. The practical difference is unification: instead of one tool for email and separate tools for phone and fraud checks, 1Lookup covers them in one place. Both are capable at what they do, but 1Lookup’s edge is combining phone, email, and IP in a single API.
Can I try 1Lookup for free?
Yes. 1Lookup offers a 7-day free trial so you can validate real phone numbers, emails, and IP addresses through the API before you pay. This lets you compare its results and developer experience directly against MillionVerifier or your current stack. You can start the trial without a long-term commitment.
Is MillionVerifier worth it in 2026?
For pure bulk email cleaning, MillionVerifier is one of the strongest value picks: 1M verifications cost $449, credits never expire, and a 100% money-back guarantee even covers risky emails it cannot verify with certainty. The buying-shape catches sit at the small end: the smallest package is 10,000 credits ($39), the rate at that size ($3.90 per 1,000) is far above the bulk rate, and the free allowance is a one-time 100 credits rather than a recurring tier. It is also strictly a verification tool, with no email finding and no phone, IP, or address lookups. If your stack needs phone or IP validation alongside email, a multi-channel per-lookup API like 1Lookup consolidates those checks on one balance.

The same month, priced both ways
Pick one of MillionVerifier’s own published volumes. Their figure is their published price at that tier; ours is the cheapest plan on our rate card that covers it. Nothing here is interpolated.
1Lookup
$99/mo
The Starter plan, 20,000 credits a month at $4.95 per 1,000. Using 10,000 of them is 50% of the plan, so $9.90 per 1,000 effective.
MillionVerifier
$39
Their published price for “10,000 verifications”, at $3.90 per 1,000.
At 10,000 a month, MillionVerifier is $60 cheaper. Our smallest plan that covers this volume includes 20,000 credits, so the gap closes as you use more of it.

MillionVerifier fine print worth reading twice
Published terms that change what MillionVerifier costs or what you can do with it. Each one links to the MillionVerifier page it was read on, because a claim about somebody else’s contract should be checkable in one click.
An account can be treated as inactive after 12 continuous months with no credits purchased and no credits used, and MillionVerifier may then remove the account and delete credentials, API keys, integrations and customer content, after at least one month's email notice; remaining paid credits themselves are not forfeited.
