Générateur de messages WhatsApp Business + modèles (IA gratuite)

WhatsApp Business message types

Four common message types covered by the generator.

**Auto-reply (away message)** — sends when a customer messages outside business hours. Should set expectation ('we reply within 4 hours during business hours, 9am-6pm GMT') and offer a fallback ('for urgent matters, email [address]').

**Greeting message** — sends when a new customer messages for the first time. Welcomes them, sets tone, asks a qualifying question to triage faster.

**Broadcast message** — sent to a list (up to 256 contacts at a time on Business app; thousands via API). Must offer value, not pitch — broadcast pitches get reported as spam.

**Customer service reply** — responds to a specific inquiry. Empathetic, solution-first, clear timeline.

WhatsApp Business API compliance

WhatsApp's Business API has strict messaging rules:

**24-hour window** — you can only reply freely to customers who messaged you in the last 24 hours. Outside that window, you must use pre-approved template messages.

**Template approval** — broadcast templates (transactional notifications, marketing messages) require Meta approval before sending. Templates can't be promotional/spammy.

**Opt-in required** — recipients must have explicitly opted into receiving WhatsApp messages from your business. No cold outreach.

**Reply rate matters** — high spam-report rates lead to messaging tier downgrades or account bans. Keep broadcast lists clean and offer value.

The generator outputs templates structured to fit these rules.

What makes WhatsApp messages convert

Three patterns from high-conversion WhatsApp accounts.

(1) **Conversational tone, not corporate** — WhatsApp is personal-feeling. Even B2B messages should feel like one person writing to another, not a brand to a customer.

(2) **Quick replies** — WhatsApp Business supports quick-reply buttons (up to 3). Use them to surface common next steps without forcing typing. Drives 30-50% higher reply rates.

(3) **Voice + media** — WhatsApp users send voice notes, photos, and videos in real conversations. Marketing messages that mix media (a short product video + text) outperform text-only.

The generator can suggest quick-reply options + media placeholders alongside the text.

WhatsApp Business greeting message examples

Greeting messages auto-fire when a new customer DMs your business for the first time. Three patterns that perform.

**Service business** — 'Hi 👋 Thanks for reaching out to [Business]. To help faster, can you share: 1) what service you need, 2) your preferred date? We reply within 1 hour during 9am-6pm GMT.'

**E-commerce** — 'Welcome to [Brand]! 🛍️ Browse our latest drops: [link]. For order help, reply with your order number. For product questions, reply with the product name.'

**SaaS / agency** — 'Hey, thanks for messaging [Company]. Quick triage: are you (a) an existing customer, (b) considering signing up, or (c) something else? Pick a number, we'll route you to the right person.'

All three set tone, set expectation, and qualify the conversation in one message.

Scheduling WhatsApp Business messages

The free WhatsApp Business app supports scheduled messages via labels + Quick Replies, but native scheduling is limited. For real scheduling (broadcasts at specific times, drip sequences, behavior-triggered messages), you need WhatsApp Business API integration via a provider (Twilio, MessageBird, Sinch, or specialized CRMs like Zoko, Wati).

API pricing (as of 2026): roughly $0.005-$0.07 per message depending on country and message type (utility messages cost less than marketing messages). Free tier: 1,000 service conversations per month included with Meta's Cloud API.

For high-volume scheduling, weigh per-message API cost vs the manual cost of sending via the Business app.
