Activate the Official WhatsApp API in minutes, cut message costs dramatically, and free your team to focus on what really matters: selling more. With SellFlux, you pay far less to use the official API while scaling your communication efficiently.
 
             
            WhatsApp’s API allows a free 24-hour conversation window whenever a customer initiates contact. SellFlux maximizes this benefit with smart engagement strategies.
The free 24-hour window opens automatically when the customer sends the first message.
Within those 24 hours, you can send unlimited messages at no cost.
Before the window closes, our system automatically sends a follow-up message to re-engage the customer.
When the customer replies, a new 24-hour window opens — and the cycle continues indefinitely.
AI-driven, personalized follow-ups increase reactivation rates, maintaining long-term relationships while using only free 24-hour windows.
