Why WhatsApp marketing works

  • Open rates far above email — most people read WhatsApp messages quickly.
  • Rich formats — images, buttons, carousels, catalogs and quick replies.
  • Two-way — customers can reply and buy in the same thread.
  • Trusted channel — it's where people already talk to people they trust.

Opt-in is non-negotiable. You can only message people who agreed to hear from you. Marketing templates need pre-approval, you're billed per delivered marketing message, and spam reports lower your quality rating and daily limits.

A 5-step WhatsApp campaign framework

  1. Segment. Split by behavior — new, repeat, lapsed, cart-abandoners.
  2. Craft the template. One clear offer, one clear button. Get it approved as marketing.
  3. Time it. Send when your audience is active; avoid message fatigue.
  4. Make it two-way. Invite replies so the free service window opens and conversation (and conversion) can continue.
  5. Measure & iterate. Track delivery, read, click and reply — then refine.

Cost tip: Marketing messages carry no volume discount and are the priciest category. Get customers to reply, and your follow-ups happen inside the free 24-hour window (until Oct 2026). Design campaigns to start conversations, not just broadcast.

Common mistakes

  • Buying lists or messaging people who never opted in — fastest route to a ban.
  • Over-sending — fatigue drives blocks and spam reports.
  • Weak CTAs — every message needs one obvious next step.
  • No segmentation — the same blast to everyone underperforms every time.
