A: Hi mike5515

1 credit = 1 email validation
Regarding our deal, we give 2M credits for 1 code, those credits never expire.
If you verify 10 meails today and in 10 month validate 100 emails we will deduct 110 credits from your total balance of 2M.

Currently we set limits per month, we do this to ensure our infrastructure will be viable and everyone receive the needed speed of validation.
Our month limit set to 100k, meaning you may not validate over 100k emails per month, however, if you want, we may not refuse, just let us know via email or chat.

Should any further questions left ping me here.

Best regards,
