How to Send Bulk WhatsApp Messages in India for Marketing & Promotions

Want to send bulk WhatsApp messages to your customers in India for a sale, a new launch or a reminder? This step-by-step guide shows how to send WhatsApp promotional messages to hundreds or thousands of people safely, when to send them in India, and how to write messages that people actually open and reply to.

3 ways to send bulk WhatsApp messages

Method	How many people	Good for promotions?
Broadcast list in the WhatsApp Business app	Small lists; only people who saved your number receive it	Only for very small lists
Bulk WhatsApp Panel (Cloud WhatsApp)	Thousands in one click	Yes — fastest, lowest-cost way to send promotions
Official WhatsApp Business API	Hundreds to lakhs, growing with your quality	Yes — verified business name, templates and automation

For real WhatsApp bulk messaging, use the Bulk WhatsApp Panel for quick, affordable promotions, and the official API when you want messages from your verified business name and automation. Avoid desktop software that sends from your personal WhatsApp — it puts your own number at risk.

What you need before you start

• A Cloud WhatsApp account: panel credits to start the same day, or the official API with your business number and verified profile.
• An opt-in contact list in Excel or CSV, ideally with name, city and language.
• One clear offer or update to send, with a photo or PDF if you have one.
• A few minutes for setup — book a free demo and our team will help you send your first campaign.

Step-by-step: how to send bulk WhatsApp messages in India

1. Collect opt-ins. Add a WhatsApp checkbox to your website forms and billing counter, or use a missed-call number or QR code. Keep a note of when and where each customer agreed.
2. Write your message. Use Hindi, English or a regional language and add the customer’s name. On the panel you can send right away; on the API, submit it as a template for approval first.
3. Segment your list. Split customers by city, language and last purchase. A Chennai customer may want a Pongal offer, while a Kolkata customer may want a Durga Puja one.
4. Personalise. Add the customer’s name, a product photo, and one clear button such as “Shop now”, “Call us” or “Book a slot”.
5. Schedule in IST. Pick a date and time when your customers are free (see below) and schedule the campaign.
6. Track and improve. Check delivered, read and replied numbers. Reply to every customer who responds, and keep improving the next message.

Best time to send WhatsApp promotions in India

There is no single perfect time for every business, but these simple rules work for most:

• Avoid late night and early morning. Messages at 11 pm or 6 am feel intrusive and lead to blocks.
• Retail and food: late morning or early evening, when people plan their shopping or meals.
• B2B: working hours on weekdays, especially mid-morning.
• Festivals: 3–7 days before the festival, with a reminder the evening before.
• Test it. Send the same message at two different times to small groups and compare read rates in your report.

How to write WhatsApp promotional messages that convert

1. Start with the benefit. “Flat discount on all kurtas this weekend” beats “Greetings from our store”.
2. Keep it short. 2–4 short lines. People read WhatsApp on small screens.
3. Add one image. A real product photo works better than a busy poster.
4. One clear button. Give one next step, not five.
5. Use their language. A message in the customer’s language feels personal.
6. Be honest. Real offers with real end dates build trust. Fake urgency gets blocked.
7. Let people stop. Add “Reply STOP to unsubscribe” to promotional messages.

Ready-to-use message examples

{{1}}, {{2}} and {{3}} are template variables. They are replaced with each customer’s name, store or time when the message is sent.

Keep delivery high

On the Bulk WhatsApp Panel you can send as many messages as your credits allow. On the official API, WhatsApp gives new numbers a daily limit and raises it as customers engage. Either way, delivery and replies stay high when customers want your messages:

• Send only to opted-in customers.
• Do not send the same promotion several times a week.
• Segment, so each customer gets relevant messages.
• Remove numbers that ask to stop, straight away.
