Whether you are having an event at your store, or a giveaway on an e-commerce website, the information that you capture is a gold mine. If you partake in Facebook giveaways to encourage engagement from your followers and gather new followers, an absolute must is to make sure they are giving you something for entering to win. Maybe you are having a gift card giveaway each week, or maybe it is a bigger prize that allows people to enter multiple times throughout a 6 month period to win. Every time they enter, they not only give you engagement with your Facebook page but also share that engagement on their facebook profile.
After you have the email address and the contest is over, send an email announcing the final winner to everyone that entered and thank them for their participation. Finally, don’t abuse the power of the gold and use the email address wisely.
