WhatsApp Auto-Reply Guide for Indian Businesses — From Away Messages to AI Bots
Auto-replies range from a basic away message to a full AI chatbot that answers from your product files. Here's a complete guide to every level — with setup instructions, examples and when to upgrade.
WhatsApp auto-replies work at 5 levels: (1) Away message in the Business App — fires outside business hours. (2) Greeting message — fires on every new contact. (3) Keyword-triggered chatbot — sends specific content when someone types a word. (4) Interactive button menu — lets customers self-select what they need. (5) AI bot — reads your product files and answers any question intelligently. Start with Level 1–2 if you're solo; upgrade to Level 3–5 as your lead volume grows.

Business hours scheduling — the most important setting
A poorly timed WhatsApp auto-message at 11 PM annoying a potential customer is worse than no message at all. Business-hours scheduling prevents this. Here's how to configure it at each level:
WhatsApp Business App
Business tools → Business hours → Set your working days and hours. Away message automatically fires outside these hours.
No-code chatbot (via WhatsApp CRM)
In your bot's automation rule, set a 'time condition': only trigger the bot flow during working hours. Outside those hours, the away-message auto-reply fires instead.
AI auto-follow-up bot
In 3Sigma's AI bot auto-follow-up settings: toggle on business-hours scheduling and select working days (Mon–Sat) and hours (10 AM–6 PM). The bot will queue follow-ups for within those windows.
Real examples from Indian businesses
Anjali — Delhi tutoring centre
Student messages at 10 PM. Greeting auto-reply fires: 'Hi! Bright Minds Coaching, Lajpat Nagar. Thanks for reaching out. Please share: (1) Class (2) Subject you need help with (3) Your area.' Anjali's team replies at 9 AM with the student's answers already in front of them — no back-and-forth to collect basic info.
Suresh — Hyderabad tiles dealer
Customer types 'price'. Keyword bot triggers and sends the full tile price list PDF in seconds. Customer replies 'do you deliver to Secunderabad?' → bot sends delivery area list. By the time Suresh's team opens WhatsApp at 9 AM, this customer is already a qualified lead with their budget and location captured.
Radha — Mumbai insurance advisor
Lead from JustDial messages at 6 PM. Interactive menu fires: [Term plan] [Health plan] [Investment plan] [Talk to advisor]. Lead taps 'Term plan'. Bot sends a comparison of the top 3 term plans Radha recommends. Outside business hours — bot scheduled to not follow up until 10 AM next morning.

WhatsApp auto-reply — FAQs
What is a WhatsApp auto-reply?
A WhatsApp auto-reply is an automated message sent to a customer when you (or your team) can't reply manually — either because it's outside business hours, or because a trigger keyword matches. The simplest form is the 'away message' in WhatsApp Business App. More advanced auto-replies use the WhatsApp Business API with a chatbot that sends specific messages based on what the customer wrote.
How do I set up auto-reply in WhatsApp Business?
In the WhatsApp Business App: tap More options → Business tools → Away message. Enable it, write your message, and set the schedule (Always, Outside business hours, or a custom schedule). For a greeting message to new contacts: Business tools → Greeting message. These are basic auto-replies built into the app — no technical setup needed.
What is the difference between WhatsApp away message and WhatsApp chatbot?
An away message sends one fixed message to everyone who messages outside business hours — no intelligence, no conditions. A WhatsApp chatbot (built with a flow builder or AI) can send different replies based on what the customer wrote: if they type 'price', send the price list; if they type 'location', send the address; if they say 'hello', start a qualification flow. Chatbots are the next level above simple away messages.
Can I set different auto-replies for different keywords on WhatsApp?
Yes — with a WhatsApp chatbot on the Business API. Set up keyword triggers: if the message contains 'pricing' or 'cost', send the rate card. If it contains 'location' or 'address', send directions and a Google Maps link. If it contains 'demo' or 'trial', send the booking link. 3Sigma's no-code flow builder lets you set these up without coding.
How do I set business hours for WhatsApp auto-reply?
In WhatsApp Business App: Business tools → Away message → Schedule → Outside business hours. Then set your business hours in Business tools → Business hours. Outside those hours, the away message fires automatically. With a CRM chatbot, you can configure business-hours rules per automation — so the AI bot follows up during working hours only, and stops after-hours follow-up to avoid annoying customers at night.
What is a WhatsApp chatbot and do I need coding skills to build one?
A WhatsApp chatbot is a rule-based or AI-powered responder connected to your WhatsApp via the Business API. You define the conversation flow: what to say when, based on what the customer writes or buttons they tap. 3Sigma's no-code flow builder uses drag-and-drop — no coding needed. For AI-powered replies that answer from your product knowledge base, 3Sigma's AI bot (available on eligible accounts) uses Gemini to generate context-aware responses from files you upload.
Should I use a simple chatbot or an AI bot for WhatsApp auto-replies?
Start with a simple keyword/button chatbot if you have predictable FAQs (price, location, product options). The flows are reliable and easy to control. Upgrade to an AI bot if your customers ask open-ended questions that need nuanced answers — like 'which product is best for my 3BHK flat?' or 'can you explain the loan eligibility criteria?' The AI bot reads your uploaded files and generates answers from them.
