Read the fine print
Before you verify any e-mails, you better make sure they're all verified, cause hunter will charge you for EVERY SINGLE query, even the unknown ones.
Even though it explicitly says "You won't be charged for duplicates or unknown results" before you try to verify.
This is by definition misleading, and very scummy.
Better read the fine print before using this very overpriced, scummy software.
07/11/2025 EDIT: The reply to this comment is a lie, the way the system charges per verification is extremely misleading.
The reply below claims 0.5 credits per verification, well I'm looking at it right now and it says 1 credit per verification, it is very inconsistent.
Furthermore they claim not to charge for "unknowns" and "duplicates". This is semi-true, very misleading yet again.
They WILL charge you for every single attempt at verification, even if the result comes back with nothing.
Snov.io for example does this fairly, they only charge for succesful verifications + catch-alls, which is what Hunter.io claims to be doing, but it's a lie, there's probably some fineprint hidden in the terms and conditions.
Don't use this service, there's so many better options out there.

Hi Anthony,
Thanks for sharing your feedback.
To clarify, Hunter doesn’t charge for duplicates or unknown results: those occur mostly when an email server doesn’t respond. Unlike many other verification tools, you only use 0.5 credit for emails that are getting verified.
You can also re-verify an email you have already verified at no extra cost during the same monthly period. Most emails found through Hunter are already verified, but you can also verify them again to ensure accuracy.
If you’d like us to review your case, feel free to reach out to [email protected], and we’ll be glad to check it for you.
Also, paid plans include monthly re-verification at no extra cost to keep your leads always up to date.
