Is there SMS marketing for membership marketing in barber shop cashier system? Seek an answer

Many businesses don't know how to make a high-precision membership marketing campaign. It's actually quite simple. We can send blessing messages and in-store promotion information to the members of the store through the SMS marketing function of the cashier system in the burning shop and barber shop before each holiday and birthday of the members, so as to maintain our relationship with customers and improve the loyalty of the members. Our store is the cashier system used by barbershops. I recommend it to you. We have used it for more than half a year and the effect is really good.
