In Hunter, your usage is measured with credits.
Two credit quotas are included in every plan:
Searches: used to find emails.
Verifications: used to verify emails.
Credits are counted as follows:
1 search credit is counted from 1 to 10 email addresses found per domain with a Domain Search.
1 search credit is counted for every email found with the Email Finder. A verification is already included at no extra cost.
1 verification credit is counted for each email processed in the Email Verifier (except for Unknown and Disposable emails that are skipped).
Our Bulk tasks will always provide the number of credits needed to process a CSV or Txt file before downloading the file. Credits will be counted based on the same criteria applied for the Domain Search, Email Finder, and Email Verifier.
The same logic applies when counting the number of requests associated with an API call.
No credits are counted if Hunter cannot provide an email.
