The Meta 72-Hour Free Entry Point (FEP) is a commercial policy where any conversation initiated from a Click-to-WhatsApp (CTWA) ad or Facebook page call-to-action is 100% exempt from per-message Meta fees for exactly 72 hours from the user first message.
- Unlike standard 24-hour service windows, Click-to-WhatsApp ads grant a full 72-hour free window with zero Meta messaging charges.
- Brands can execute a multi-touch follow-up sequence (at 2h, 24h, and 48h) completely free of charge before the window expires.
- WA-CRM automatically tracks the exact second the 72-hour window closes, ensuring zero accidental billing leaks.
Most businesses running Meta ads in Pakistan do not realize that every Click-to-WhatsApp ad click opens an official 72-hour free messaging window. You do not pay Meta a single cent for any message sent during these 3 days. Here is how high-performance brands structure their follow-up cadences to close sales within this free window.
1. Calibrating the 72-Hour Conversion Sequence
Hour 0: Instant qualification and catalogue delivery.
Hour 24: Customer reviews, social proof, and FAQs.
Hour 68: Final call incentive (free express shipping or limited discount) sent right before the 72-hour window expires.
