Hi Alison! It differs from sweep to sweep. Be sure to check the official rules for a guaranteed answer. Usually winner notification is by email. Sometimes it's a phone call or a message on social media. In some cases, sponsors will just ship the prize to you without notice. I definitely reccommend checking email daily and checking spam once in a while too, just in case!Congratulations! How does we know if we won or not? For any sweepstakes. Do you get an email? And how do you tell its not spam?
