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 Proofy's accuracy, and ours has not been independently tested either. Our accuracy guarantee refunds the difference when a bulk list's valid and invalid results are less than 99.2% right.
