The overview of your top 10 most active members can be found on the front of the control panel.
To thank the customers for their loyalty, you can easily click "Create campaign" above the members to create a coupon and an SMS that will be sent only to these members.
Tip! Do you not want to send an offer, but an invitation or similar? Use the same function, but set the coupon to 0 discount. Thus, it can function as a kind of "ticket" instead.
