WhatsApp Business Marketing: Best Practices
How to use WhatsApp Business API to market effectively and keep your number healthy in Tanzania.
WhatsApp Marketing Is Different from SMS
WhatsApp has stricter rules than SMS — but delivers richer engagement. Getting it right builds loyalty. Getting it wrong gets your number banned.
The Opt-In Requirement
You cannot send WhatsApp marketing to people who haven't opted in. Valid opt-in methods: website form checkbox, in-store QR code, SMS opt-in, or existing contacts who messaged you first.
Template vs. Free-Form Messages
Templates — Pre-approved by Meta. Used for outbound campaigns (promotions, alerts). Must be approved before use.
Free-form — Any message type, but only within 24 hours after a customer messages you.
Protect Your Quality Rating
- Only message opted-in contacts
- Max 1–2 marketing messages per week
- Make opt-out easy — "Reply STOP to unsubscribe"
- High block rate or report rate drops your quality and can get your number banned
High-Performing Message Types in Tanzania
- Flash sales with countdown urgency
- Order confirmation and delivery updates
- Appointment reminders (clinics, salons, banks)
