Your customers might ignore a promotional email, but they almost always open a WhatsApp message. That makes WhatsApp a powerful retention channel, and an easy one to abuse. The brands that win treat it like a conversation, not a billboard.
Five flows to set up first
- Order confirmation and updates. Useful, expected and a great way to earn the right to message later.
- Abandoned cart. A friendly reminder with a direct link back to the cart, sent within the hour.
- Cash-on-delivery confirmation. In COD-heavy markets, a quick confirm button reduces failed deliveries.
- Reorder reminders. Timed to how long the product actually lasts, not a random schedule.
- Win-back. A personal note and a reason to return for customers who have gone quiet.
Rules that keep you welcome
- Collect clear opt-in and make opting out easy.
- Use approved templates for business-initiated messages, as the WhatsApp Business API requires.
- Send fewer, better messages. Every message should be useful on its own.
- Reply like a human. Quick answers turn a broadcast into a relationship.
