A sweepstakes is a lottery in which the winners are determined before notifying all participants, who are automatically entered without any action required. Results can be viewed immediately via a toll-free number, a website, a scratch-off ticket, by mailing a reply slip, or by visiting a retail location. This type of lottery is not used to build a contact list, as this must be established before the draw. Its primary objective is to engage or qualify a database of prospects or customers.
