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)
  • Loyalty reward notifications
  • Product launches with images and order link
BSUID — July 2026 Update: Meta is rolling out Business-Scoped User IDs for WhatsApp users who adopt usernames. Sakura SMS will handle this automatically — no action needed on your end.
