Can I have 5 people share my youtube channel on social media and reward them with a coupon code for $1 off a graphic? Would that be possible with InviteBox? Steve Hall April 12, 2015 22:28 Follow Yes, This is basic functionality with the InviteBox system, but a larger reward may work better. Related articles I would like is to send an email to my subscriber list of about 10,000 people asking them to refer their friends and they will receive one entry in our sweepstakes per friend. Is this possible with InviteBox? Comments 0 comments Please sign in to leave a comment.
