  • You get 200 email validations/day,use them wisely!
  • When using the -a option,avoid using small words(ex:j,3,66),the shorter the words are the bigger the email list is and therefore more validations are needed
  • when adding an email pattern make sure the service providing the pattern displays it with the right size(facebook,twitter,instagram do…others might not)
  • I dont recommend using with Tor as haveibeenpwnd.com,hunter.io and google wont function properly
