Loyalty programs are a popular and common method to reward your customers and especially to repeat customers.
Customers like to be rewarded and it encourages them to think favourably about your ecommerce website and to return on a regular basis.
You can set how often and how much that you reward your clients and how they can redeem their rewards.
Loyalty programs also give you valuable information about your customers and their spending habits. This information can be used in tailoring your marketing activities.
