This is one of the most important questions.

Once someone buys the offer you send them (read the previous question) then they join your loyalty program.

This means:

• You get their data like name, email and telephone number
• You can email them each time you want them to come back. A cafe client emails his database of 3,450 clients each month via LoyaltyNation.io and manages to get a staggering 20% to visit their business in the following 3 days. This results in sales of more than 10,000 Euros per month on average.
• You can send them an SMS message, right from the app and ask them to buy your special, or announce a new product you just brought
• You can also send them a free PUSH notification, or schedule it so when any registrant is within a certain proximity from your store, to instantly get the notification

This means, that by regularly promoting your offers, products, new products or services to your list you will be attracting new and retaining old clients, simply by being in front of them.
