Karen M Designs review for Smile: Loyalty Program Rewards

Positive reviews MUST be fake. This is TERRIBLE! I watched as 6 people signed up for my rewards program yesterday and not one is in my database now. This thing sent them a confirmation email, they went to spam folders. It gives a code that you then have to go back to the website to be added to my reward program. When they clicked the link - it gave them a 404 error. I just checked and it is now NOT LIVE on my website even tho it's showing in the Shopify store. Waste of time. Customer support is useless.
