WhatsApp marketing is promoting and selling over WhatsApp: offers, new arrivals, reminders and follow-ups sent as WhatsApp messages to customers who agreed to hear from you. It works because WhatsApp is where your customers already talk, more than 3 billion people in over 180 countries use it, and a short message in that inbox gets seen the way an email in a promotions tab doesn’t.
It is also the most tightly policed marketing channel you’ll use. Meta requires opt-in, holds you to a quality rating, and limits how many people you can message a day, so the businesses that win on WhatsApp are the ones that message fewer people, better. This guide covers the rules, app vs API, the campaign types, costs in India and the mistakes that get numbers banned.
Why WhatsApp beats email for attention
Marketing blogs love to quote WhatsApp open rates of 90% and more. We won’t, because we can’t verify those figures. The reasons the channel works don’t need them:
- It’s the same inbox as family and friends. Your message sits in the chat list people already check through the day, not in a promotions tab.
- Every message is accounted for. On the API you see sent, delivered, read and failed per contact, so you measure your own numbers.
- It’s two-way. A customer can reply “Is COD available?” to your offer and buy in the same chat, straight from your WhatsApp catalog. Email ends at the click; WhatsApp starts a conversation.
- Replies are cheap or free. Once a customer writes to you, you can reply free-form for 24 hours, and Meta’s pricing gives each number 1,000 free service replies a month.
The flip side: because WhatsApp is personal space, Meta protects it, and one rule decides everything else. Ignore it and you meet the walls covered in why broadcasts quietly miss customers and how bulk senders get numbers banned.
Rule number one: opt-in
Meta’s Business Messaging Policy allows you to message people only if they gave you their number and agreed to hear from you, and it requires you to respect every request to stop, whether the customer says it on WhatsApp or anywhere else. You are responsible for how you collect that consent, and Meta recommends a separate opt-in for each kind of message, such as offers and order updates.
Opt-in that holds up:
- A WhatsApp tick-box on your website, signup or checkout form, with your business name next to it
- A customer messaging you first, including from a Click-to-WhatsApp ad, a wa.me link or a QR code in the shop
- A “Reply YES to get offers on WhatsApp” message, and the YES
- A line on the bill or invoice the customer signs
A bought list or numbers scraped from a group is not opt-in; it brings blocks, and blocks wreck your quality rating. Wording and record-keeping: WhatsApp opt-in and consent explained. Our free WhatsApp link generator makes wa.me links and QR codes for customers to message you first.
Want our offers and new arrivals on WhatsApp? Reply YES and we'll add you. Reply STOP anytime to opt out.
App or API: which WhatsApp do you market from?
Both are official, and the Business app grew up in 2026: an AI agent that answers customers (Business AI in India, then Meta Business Agent), more devices for a team, and paid business broadcasts in some countries. What still needs the API: campaigns sized by Meta’s messaging limit, per-contact delivery reports, workflows and integrations.
| WhatsApp Business app | WhatsApp Business API | |
|---|---|---|
| Sending offers | Broadcast lists: 256 per list, only to people who saved your number. Paid business broadcasts (select countries) also reach unsaved contacts | Approved template campaigns to opted-in customers; no saved-number rule |
| Sending limit | 256 per broadcast list | 250 unique customers per 24 hours to start, 2,000 after verification, then 10,000, 100,000 and beyond |
| Team | 4 linked devices; up to 10 devices and agents with paid Meta Verified | Your whole team in a provider’s shared inbox |
| Automation | Greeting and away messages; Meta’s AI agent for eligible businesses | Workflows and integrations through your provider |
| Reports | Ticks per chat; read and reply rates for business broadcasts | Sent, delivered, read, failed per contact |
| Cost | Free app; paid extras such as business broadcasts and Meta Verified | Per message, billed by Meta: ₹0.8631 marketing, ₹0.115 utility, + 18% GST |

The campaign types that work
1. Broadcast campaigns
One approved Marketing template, with an opt-out line, to a segment of opted-in customers: a new collection, a price drop, a festival offer like those in Diwali WhatsApp messages for business. Step by step: how to send a WhatsApp broadcast message; wording to start from: 30+ template examples.
Hi {{1}}, our winter collection is in store from Saturday. Show this message for 10% off until 30 November. Reply STOP to opt out of offers.
2. Drip sequences
A series spread over days, such as a mini-course or a 7-day routine that ends with one offer. A customer sends a keyword and the whole series is queued. The build: WhatsApp drip campaign automation.
3. Abandoned cart recovery
One friendly reminder with a link back to the cart, sent a couple of hours after a checkout is left unfinished, while the shopper still remembers what they wanted.
4. Click-to-WhatsApp ads
Facebook and Instagram ads that open a chat with you, so the lead arrives already talking. When you reply, Meta opens a free entry point window in which it doesn’t charge for your messages (Meta's pricing page has the current rules). Setup: the Click-to-WhatsApp ads guide.
5. Replies that sell
Not a campaign, but where the money is made: answering enquiries fast. An instant auto reply holds the customer until a person takes over (25 auto replies you can copy), a no-code chatbot answers the common questions, and a WhatsApp Flow form collects booking or lead details inside the chat. Meta’s policy allows automation as long as customers have a clear way to reach a person.
A 6-step WhatsApp marketing strategy
- Collect opt-ins everywhere. Website tick-box, checkout, QR at the counter, wa.me link in your Instagram bio. Record when and how each person agreed.
- Segment from day one. Tag customers by what they buy and how recently. “Saree buyers, last 90 days” beats “everyone”. A WhatsApp CRM keeps those tags current for you.
- Write templates in the right category. Offers are Marketing, order updates are Utility; mixing them gets the whole message charged as Marketing (template categories explained).
- Start small and watch quality. Your limit starts at 250 unique customers per 24 hours anyway, so begin with your warmest segment, watch blocks and reads, then widen.
- Measure per contact. Delivered, read, replied, opted out. Drop what people ignore, repeat what they answer.
- Prune ruthlessly. Honour every STOP at once and rest contacts who never read you. A smaller list that reads you beats a big one that blocks you.
What WhatsApp marketing costs in India
Meta charges per delivered message, billed to your Meta business account. Rates for Indian numbers from 1 October 2026, excluding 18% GST (full detail: WhatsApp Business API pricing in India):
| Message type | What it’s for | Rate per message |
|---|---|---|
| Marketing | Offers, festival greetings, new arrivals, win-back | ₹0.8631 |
| Utility | Order updates, reminders, receipts | ₹0.115 |
| Authentication | One-time passcodes | ₹0.115 |
| Service | Your replies within 24 hours of a customer’s message | First 1,000 free each month, then ₹0.115 |
So a 2,000-customer offer costs 2,000 × ₹0.8631 = ₹1,726.20 plus GST. Marketing messages are where the money goes, one more reason to segment. Your provider’s fee is separate. Estimate your month with the cost calculator.
The mistakes that get numbers banned
- Bulk-sender apps, browser extensions, GB WhatsApp. They automate the normal app, and WhatsApp’s Terms of Service name bulk messaging and auto-messaging as impermissible. The usual result is a banned number (sending bulk messages without getting banned).
- Bought or scraped lists. No opt-in means blocks and reports, and Meta’s policy says businesses can be limited based on that feedback.
- No opt-out line. A customer who can’t find STOP presses Block, and blocks drag your quality rating down.
- Daily blasts to everyone. Meta holds back some marketing messages “to maintain healthy ecosystem engagement” (error 131049), so over-messaging mostly buys failed sends.
- Offers tucked into order updates. Meta re-categorises the template as Marketing, and repeat misuse brings restrictions.
If a number is already restricted or banned, the recovery steps are in WhatsApp Business account banned or restricted.
How WaBot handles this
WaBot is a WhatsApp Business API platform, so the pieces above are one dashboard:
- Campaigns to contacts, groups or tags, with blocked contacts excluded automatically and nobody getting the message twice. Launch Options offers Send Now or Schedule for Later with a date and time (all the options: how to schedule WhatsApp messages).
- Per-contact results: sent, delivered, read and failed with the reason in plain words, and the inbox shows your current tier (for example “Tier 250” or “Tier 2K”) and a quality dot.
- Drip series as workflows on the Base Plan: one keyword queues the whole sequence on the server, each message with its own wait.
- An auto response and an AI agent answer first messages in seconds, any time of day, and hand over to your team in one shared inbox. AI usage is pay-as-you-go from your WaBot wallet.
Campaigns are on the Starter plan (₹840/month + GST); workflows are on the Base Plan (₹9,240/year + GST). The Free plan lets you sign up and connect your number, and connecting starts a 15-day Base Plan trial. Meta’s message charges are billed by Meta directly, with no WaBot markup. Questions?

Frequently asked questions
What is WhatsApp marketing?
WhatsApp marketing is promoting your business over WhatsApp: offers, new arrivals, reminders and follow-up conversations sent to customers who opted in. You can start on the WhatsApp Business app with broadcast lists, or paid business broadcasts where WhatsApp offers them. Campaigns to a growing opted-in list, with per-contact reports, workflows and integrations, run on the WhatsApp Business API.
Is WhatsApp marketing legal?
Yes, within Meta’s Business Messaging Policy: you may only message people who gave you their number and agreed to hear from you, you must honour every opt-out, and messages that start a conversation must be Meta-approved templates. Spam and bulk-sender tools break those terms and get numbers banned.
How much does WhatsApp marketing cost in India?
Meta charges per delivered message: ₹0.8631 for marketing and ₹0.115 for utility or authentication messages from 1 October 2026, plus 18% GST, billed by Meta directly. Replies within 24 hours of a customer’s message are free for the first 1,000 each month. Your provider’s plan is separate; WaBot plans start free, with campaigns from ₹840/month + GST.
How many people can I message on WhatsApp?
On the Business app, broadcast lists cap at 256 contacts and only reach people who saved your number; paid business broadcasts, available in select countries, don’t need the saved number. On the API, approved templates reach opted-in customers up to Meta’s messaging limit: 250 unique customers per 24 hours to start, 2,000 after business verification, then 10,000, 100,000 and beyond when quality stays high.
The bottom line
WhatsApp marketing in 2026 is a permission game: collect real opt-ins, segment, send approved templates sparingly, and answer fast when people reply. The businesses that treat the channel like a trusted chat, not a loudspeaker, keep their quality rating and sell in the same thread where the customer said hello.
