On the Integration > POS & eCommerce sites page, a Shopify site may not have been turned ON yet.

When your Shopify site is turned on, you'll be able to collect data from each individual Shopify site and use Marsello's retention marketing features to help increase your customer loyalty. Customers will be able to earn points, redeem rewards and redeem campaign discount codes.
 

If you want customers to earn points, redeem discounts, and sales data to trigger emails, you’ll need to turn the sites you wish Marsello to work with ON.

1. In your Marsello Admin, select Integration > POS & eCommerce sites from the Navigation.

2. Select the sites that you want to use Marsello on by clicking the OFF toggle to turn a site ON.

When a site is on, you will then be able to add customers to your loyalty program, automatically reward points for purchases and redeem loyalty and promotional discount codes from that site.
