Small doubt you extracted usernames along with emails or just usernames ? Cause one of the user was guiding about regex which is best option but that works only when you have emails but not usernames. And these comes under cold mailing i doubt any company would allow to send to those emails they simply ask you to verify that you know these list something like verification which is nonsense.
Good luck.
