A credit is a search within the tool. Each time you perform a search, a credit will be deducted from your account.
We charge 1 credit per search, even when the email is not found. This is because we apply more than 14 verification processes before delivering any results. In comparison, other competing tools simply give you a random email permutation without any verification.
Please note: we do not charge for repeat leads that you have searched for during the month.
