$ buster -e [email protected]
Query for list of emails`
$ buster --list emails.txt
Generate emails that matches the pattern and checks if they exist or not(use the -a argument if you have more info to add(ex: -a nickname fav_color phone #)

$ buster -u johndoe
Generate a company email and returns info associated with it
$ buster -f john -l doe -c


  • 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, and google wont function properly
