WhatsApp loyalty coupons in brief
WhatsApp loyalty coupons after purchase are reward messages that reach the customer seconds after the bill is closed, while the salon visit or shop trip is still fresh. WappBlaster delivers them through its Coupon & Loyalty Management product, made for salons, kirana shops and other retail that bills at a counter. Typical offers are a stamp card such as visit 5 get 1 free, ₹200 off the next service, or a festival deal, each carrying an expiry date and plain terms. The coupon can be tied to billing through a POS webhook or sent by hand, and it can follow a COD delivery as well as an in-store sale. At the counter, staff validate each code in the WappBlaster Android app before applying it, which stops expired or reused coupons slipping through. Time-boxed offers can also trigger an automatic reminder shortly before they lapse. Setup fits into one afternoon: build the templates with their expiry and terms, hook them to the bill, and show staff how redemption works.
