EngageApp is the AI-native retention product for small e-commerce shops — abandoned-cart recovery, win-back, and lifecycle messaging across email, SMS, WhatsApp, and push. You pay per message successfully sent, not per profile stored.
It is built and operated by Mantissa Software Solutions Ltd. The product lives at engageapp.xyz — not engageapp.co.
