here's one way of doing it using a recursive function

def return_name_and_email(hash)
  if hash['name'] && hash['email']
    puts "Name: #{hash['name']}"
    puts "Email: #{hash['email']}"
  end 

  hash.keys.each do |key|
    return_name_and_email(hash[key]) if hash[key].is_a?(Hash)
  end 
end

return_name_and_email params
