WhatsApp auto-message: complete guide (2026)

Auto-message is step zero of WhatsApp automation — and most companies set it up wrong. This guide shows the 5 types that matter, when to use each, and how to set up with no code.

Types of auto-message

1. Welcome

Fired on first contact message. Don't use to "sell" — use to confirm receipt and promise a next step.

"Hi! Got your message. I'll reply in up to 15 min during business hours (Mon-Fri 9am-6pm). Outside that, I return next business day 🙏"

2. Away (outside hours)

Only fires outside business hours. Tell them when you'll be back.

3. Qualification

Bot asks what's needed before human steps in. Accepts free text or buttons.

4. Confirmation/reminder

Appointment reminder, order confirmed, delivery ETA. Fires at scheduled time.

5. Post-sale

X days after purchase: asks for review, offers cross-sell, rebuilds relationship.

Official API vs extension

• WhatsApp Business app — welcome, away, basic quick replies. Limit: ~3 templates.
• Official API (with BSP) — unlimited automation but with per-conversation cost and template approval bureaucracy.
• WhatsApp Web extension (Zapext) — full automation, no per-message cost, 1-click install. Ideal for 99% of SMBs.

When NOT to automate

• Premium customer in sensitive negotiation.
• Serious complaints or crisis — always human.
• Beginning of consultative B2B high-ticket sales.

How to set it all up in Zapext

1. Install the free Chrome extension.
2. In Chatbot, set keyword (e.g. "hi", "hello", "price") and action (text, audio, media, transfer to human).
3. In Scheduling, program recurring messages (welcome, away, post-sale).
4. Test with your own number before enabling for everyone.
