You could pass the two arrays into the method, then populate them in there:

invalid_emails = []
valid_emails = []
parse_emails('long list', valid_emails, invalid_emails)


def parse_emails(emails, valid, invalid)
  .... stuff
  while ...
    if is_valid?
      valid << current_email
    else 
      invalid << current_email
    end
  end
end

valid_emails, invalid_emails = parse_emails(whatever)

Please take time to read some basic intro into Ruby syntax ;)

Construct an class with two lists in it, one for valid emails and one for invalid emails and populate the object of this class in parse_emails function and return it.

Then, in the outside, you can access those two lists as properties of the return value.
