Two email verification services, side by side. We cost less per 1,000 credits at 9 of the 10 sizes compared, and we guarantee 99.2% accuracy on bulk lists, refunding the difference when a list falls short. MillionVerifier has credits that never expire, a lower price on its 1,000,000 pack ($449 against our $450), a published time for 1,000,000 emails (about 6 hours; we have not timed a list that size yet) and a money-back guarantee for uploaded lists with more than 4% hard bounces.

Accuracy
Accuracy and what each one promises
Every verifier says it is accurate. What matters is what you get back when it is not.
email-validation.org
99.2%guaranteed on bulk lists
We guarantee that at least 99.2% of the valid and invalid results of every bulk list are right, or we refund the difference.
Refund = 99.2% minus the measured accuracy, as a share of what the list cost. A list at 70% gets 29.2% back, paid to the original payment method.
Claim within 15 days with your bounce evidence. A person decides every claim.
Not covered, among others: catch-all, disposable and unknown results (unknowns are never charged) and single checks. The guarantee page lists every condition.
We have not tested MillionVerifier's accuracy, and ours has not been independently tested either. Both publish a refund promise: MillionVerifier's money-back guarantee for uploaded lists with more than 4% hard bounces, and our accuracy guarantee when a bulk list's valid and invalid results are less than 99.2% right, refunding the difference.
