WhatsApp Keyword Automation, Auto-Replies & Drip Campaigns | Complete Setup Guide for Indian Businesses
WhatsApp automation for Indian businesses goes far beyond a simple "Hi, thanks for your message, we'll reply soon." When done properly, WhatsApp automation is a complete sales and marketing system — qualifying leads, nurturing cold prospects, recovering abandoned carts, sending timely reminders, and closing deals, all without a human pressing send.
This guide covers the three core automation types every Indian business should set up: keyword automations, auto-reply flows, and drip campaigns (sequences). Plus, how to layer them with a bulk broadcast strategy for a complete WhatsApp marketing system.
WhatsApp Automation Type 1: Keyword Automations
What it is: A keyword automation fires a specific response when a customer sends a message containing a particular word or phrase. It's the foundation of WhatsApp chat automation.
How Keyword Automations Work
When a contact sends a message to your WhatsApp business number, ZazzyAgent scans it for keywords you've defined. If a match is found, the associated response or flow triggers immediately — before a human sees the message.
Basic keyword automation examples:
| Customer sends | Automation triggers |
|---|---|
| "price" or "pricing" | Send price list PDF + ask which product they want details on |
| "demo" | Send demo booking link / offer to schedule a call |
| "hi" or "hello" | Send welcome message + menu |
| "location" or "address" | Send Google Maps link + clinic hours |
| "cancel" | Send cancellation process information + offer retention discount |
| "help" | Send support options menu |
| "book" or "appointment" | Trigger appointment booking agent flow |
| "track" or "order" | Trigger order tracking flow (pulls data via webhook) |
| "refund" or "return" | Send return policy + create support ticket |
Setting Up Keyword Automations on ZazzyAgent
Step 1: Go to Flow Builder → Create New Flow → Set Trigger to "Keyword Received"
Step 2: Enter your trigger keywords. ZazzyAgent supports:
Exact match: Only fires if the message is exactly that word
Contains: Fires if the keyword appears anywhere in the message
Starts with: Fires if the message begins with the keyword
Regular expression: For advanced pattern matching
Step 3: Build the response flow. This can be as simple as a single message or as complex as a multi-step qualification flow with conditions and branching.
Step 4: Set priority. If a message could match multiple keywords, you can define which automation takes precedence.
Step 5: Publish. The automation goes live immediately on WhatsApp (and optionally Instagram, Facebook, Telegram simultaneously).
Advanced Keyword Automation: The Menu System
Build a structured menu that customers can navigate using keyword triggers:
Welcome message (triggers on "hi", "hello", "hey"):
"Welcome to [Business Name]! 👋 How can we help you today? Reply with: 1 — Products & Pricing 2 — Book an Appointment 3 — Track My Order 4 — Speak to Our Team"
Each number triggers its own sub-flow. This creates a self-service system that handles the majority of routine enquiries without any human involvement.
Keyword Automation for Lead Qualification
Keyword automations can also serve as the entry point for full qualification flows. A solar company might set this up:
Customer sends: "solar" (from a Google search landing on their WhatsApp link)
Automation triggers:
"Hi! Thanks for your interest in solar panels 🌞 We're ZazzyAgent Solar — helping Indian homes go solar with subsidy. To check your eligibility and savings, can I ask: what's your monthly electricity bill?"
The customer replies, and the qualification flow runs — collecting electricity bill, roof type, location, ownership — without any human involvement.
WhatsApp Automation Type 2: Smart Auto-Replies
Auto-replies go beyond keywords. ZazzyAgent supports several types:
Away Message Automation
Set up an auto-reply that fires when a message arrives outside your business hours:
"Hi! Thanks for reaching out to [Business Name] 😊 We're currently closed (our hours are Mon–Sat, 10 AM – 7 PM). We'll respond first thing tomorrow morning! Meanwhile, here's our product catalog: [link]"
Configure this with ZazzyAgent's business hours settings — the auto-reply fires automatically during off-hours and pauses during working hours.
First-Message Automation
A different auto-reply fires the first time a new contact ever messages your WhatsApp — welcoming them to your business before any human is involved:
"Welcome to [Business Name]! 🎉 Thanks for reaching out. I'm here to help you right now. What can I assist you with today? [Product Enquiry] [Book Appointment] [Support]"
Session-Reopening Automation
When a conversation has been inactive for 24+ hours and the customer sends a new message, a session-reopening automation can fire:
"Welcome back, {{name}}! 👋 Just picking up from where we left off — how can I help you today?"
WhatsApp Automation Type 3: Drip Campaigns (Sequences)
A drip campaign (also called a sequence) is a series of pre-written messages that send automatically over time — without any human involvement. It is the WhatsApp equivalent of an email nurture sequence.
How Drip Campaigns Work
A contact enters the sequence (via trigger: comment, ad click, form submission, or manual add)
Message 1 sends immediately (or after a set delay)
Message 2 sends on Day 3
Message 3 sends on Day 7
Message 4 sends on Day 14
And so on — for as long as you define the sequence
If the contact replies at any point, the sequence can pause for human review, or continue running depending on your settings.
Setting Up a WhatsApp Drip Campaign on ZazzyAgent
Step 1: Go to Flow Builder → Create Sequence Flow
Step 2: Define the entry trigger:
Contact is added to a specific list/tag
Contact submits a WhatsApp Form
Contact clicks a Click-to-WhatsApp ad
Webhook event (e.g., customer signs up on your website)
Contact is manually added by a team member
Step 3: Build your message sequence:
Day 0 (immediate): Welcome + core value proposition Day 1: Share a case study or testimonial Day 3: Address the most common objection Day 5: Limited-time offer or scarcity nudge Day 7: "Just checking in" personal-feeling follow-up Day 14: Final value-add + strong CTA Day 21: Re-engagement question ("Are you still interested?") Day 30: Soft close or unsubscribe option
Step 4: Use dynamic variables to personalise every message:
{{name}} — customer's first name
{{city}} — their location
{{product}} — the product they enquired about
{{date}} — the date they first messaged

Frequently Asked Questions
Q: What is WhatsApp keyword automation? A: WhatsApp keyword automation is a system that detects specific words or phrases in incoming messages and automatically triggers a pre-defined response or conversation flow. When a customer sends "price," for example, the automation instantly sends your price list — without any human involvement.
Q: Can I set up WhatsApp auto-reply for specific times? A: Yes. ZazzyAgent supports time-based auto-replies — away messages that fire during off-hours and pause during business hours. You can define your business hours in the settings and ZazzyAgent switches between live agent mode and auto-reply mode automatically.
Q: What is a WhatsApp drip campaign? A: A WhatsApp drip campaign is a series of pre-written messages that automatically send to a contact over time. Like an email drip sequence, it runs without human input — sending Day 1, Day 3, Day 7 messages automatically based on when the contact entered the sequence.
Q: How many contacts can I send WhatsApp broadcasts to? A: With ZazzyAgent's WhatsApp Business API, there is no contact limit on broadcasts. You can send to your entire opted-in database simultaneously — whether that's 500 or 500,000 contacts. This is a key difference from the WhatsApp Business App, which limits broadcasts to 256 saved contacts.
Q: Do WhatsApp drip campaigns work with Instagram and Facebook too? A: ZazzyAgent's sequence and flow builder works across WhatsApp, Instagram, Facebook Messenger, and Telegram. You can build a nurture sequence that runs on WhatsApp, or separately configure one for Instagram DM contacts.
Q: Is WhatsApp keyword automation allowed by Meta? A: Yes. Keyword automation and drip campaigns using the official WhatsApp Business API are fully allowed by Meta. They run through your WABA (WhatsApp Business Account) using approved message templates or within the 24-hour customer-initiated conversation window, both of which are compliant with Meta's Business Messaging Policy.
Q: Can I personalise WhatsApp drip campaign messages for each contact? A: Yes. ZazzyAgent supports dynamic variables in every message — {{name}}, {{city}}, {{product}}, {{date}}, or any custom field you've captured in the contact's profile. This means 10,000 drip campaign messages all feel individually written.
