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.
Marketing message types that perform
| Campaign | What it does | Why it converts |
|---|---|---|
| Welcome / opt-in | Greets new subscribers | Highest engagement moment |
| Abandoned cart | Nudges an unfinished purchase | Recovers otherwise-lost revenue |
| Product launch | Announces new arrivals | Drives fast, visible demand |
| Back-in-stock | Alerts interested buyers | High intent, low cost |
| Re-engagement | Wins back quiet customers | Cheaper than new acquisition |
| VIP / loyalty | Exclusive offers to best buyers | Boosts lifetime value |
A 5-step WhatsApp campaign framework
- Segment. Split by behavior — new, repeat, lapsed, cart-abandoners.
- Craft the template. One clear offer, one clear button. Get it approved as marketing.
- Time it. Send when your audience is active; avoid message fatigue.
- Make it two-way. Invite replies so the free service window opens and conversation (and conversion) can continue.
- 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.
