TL;DR
A WhatsApp auto-reply is a message your business sends automatically when a customer writes to you — so no one is ever left waiting, even at night or on weekends. This complete guide covers everything from the basic built-in feature to a full AI setup that answers real questions, plus templates you can copy today.
A WhatsApp auto-reply is an automated response triggered when a customer messages your business. There are two levels. The first is the built-in auto-reply in the free WhatsApp Business app: a greeting message for new contacts and an away message outside your working hours. These are fixed — they say the same thing to everyone and cannot answer a question.
The second level is an AI auto-reply: instead of a canned line, the bot reads each customer's question and answers it from your business information — prices, availability, policies, hours — and hands off to a human when needed. That is the difference between "we'll reply soon" and an actual answer in seconds.
There are two paths depending on what you need. Start with the built-in option if you just want a greeting; move to AI when you want real answers.
That is the ceiling of the built-in feature: two automatic messages and a few saved shortcuts. It cannot understand or answer questions.

Use these as-is or adapt them to your brand voice. Keep replies short, warm, and clear about the next step.

A few avoidable mistakes are what separate an auto-reply that helps from one that annoys customers:
The best auto-reply does more than acknowledge a message — it moves the conversation forward. Acknowledge the customer, set a clear expectation for what happens next, and give them a reason to stay engaged. If you promise a response time, keep it realistic so you can always beat it.
Match the customer's language and dialect, keep sentences short, and lead with the answer rather than pleasantries. And whenever possible, let AI handle the actual question instead of a fixed line: an instant, specific answer from your own data converts far better than "we'll get back to you," because it removes the wait that sends customers to a competitor.
Yes. The WhatsApp Business app has built-in greeting and away messages, but these are fixed and don't answer questions. For real answers, connect your number to an AI platform like RevoplyAI through the official WhatsApp Business API.
The WhatsApp Business app's basic greeting and away messages are free. AI auto-reply that actually answers customer questions is available on RevoplyAI's free plan with no credit card, with paid plans starting at $29/month as your volume grows.
Not with the official API. Bans come from unofficial automation apps and modified clients. RevoplyAI is a verified Meta Tech Provider and connects through the official WhatsApp Business API built for automated business messaging. See automating WhatsApp without ban risk.
Keep it short, warm, and clear about what happens next: acknowledge the message, set a response-time expectation, and point to a next step. With an AI bot you don't need canned text at all — it answers the customer's actual question instantly.
