The problem with unofficial bulk senders

Why “bulk sender” software is risky

Against WhatsApp's terms

WhatsApp doesn't allow bulk or automated messaging from the normal WhatsApp or WhatsApp Business app — tools that do it break those terms.

Numbers get banned

When many people report or block a number, WhatsApp can restrict or ban it — and with it every chat your customers know you by.

Replies get lost

Answers land on one phone. No assignment, no team, no record of who replied.

The official way

Send bulk WhatsApp messages in 4 steps

Get the WhatsApp Business API

Lead Pattern (Official Meta Tech Provider) connects your business number. Setup is free.

Write the message — or copy one from our free template library — and submit it to Meta.

Upload your list

An Excel file with one row per customer (up to 10,000 per upload), or a saved segment of your customers.

Send or schedule

Each customer gets their own one-to-one message. Track sent, delivered, read and failed.

Side by side

Unofficial bulk sender vs the official API

	Unofficial bulk sender	WhatsApp Business API (Lead Pattern)
Allowed by WhatsApp	—
Risk to your number	High — reports and blocks lead to bans	Low when you message opted-in customers with approved templates
Personal values per customer	Depends on the tool	Yes — name, invoice, amount per row
Buttons (Shop now, Track order)	Rarely	Yes — quick replies, website and call buttons
Delivery and read reports	Rarely reliable	Yes, per broadcast
Replies	One phone	Shared team inbox with assignment and notes
Green tick	—	Possible — Meta decides

What it costs

Cost of 1,000 bulk WhatsApp messages (India)

Message type	Example	Meta charge per 1,000 (approx.)
Marketing	Offers, festival greetings, new launches	≈ ₹860
Utility	Payment reminders, order and delivery updates	≈ ₹115
Authentication	One-time passcodes	≈ ₹115

Indicative Meta rates for India, excluding GST; actual charges follow Meta's rate card. Lead Pattern passes Meta's rates through with zero markup; your plan is separate.

How many messages can I send a day?

WhatsApp limits how many different customers one number can start conversations with in 24 hours. New numbers usually start at 250, then move up to 2,000, 10,000, 100,000 and unlimited as you complete business verification and keep a good quality rating. Replies inside an open conversation don't count. Messaging limits explained →

Keep your number healthy

Message people who opted in — website forms, checkout, ads, or customers who messaged you first.
Make it easy to stop: a "Stop offers" button. Opted-out customers are removed from audiences automatically.
Use segments (bought in the last 90 days, city, interest) instead of messaging everyone.
Watch your quality rating — a red rating can lower your limit. Account blocked or limited? →

Bulk WhatsApp FAQ

What is the safest way to send bulk WhatsApp messages?+

Use the official WhatsApp Business API through a provider like Lead Pattern: approved templates, opted-in customers and your own verified business number.

Can I send bulk WhatsApp messages from Excel?+

Yes. Upload an .xlsx with one row per customer — up to 10,000 rows per file — and each row fills the template with its own values. [See how →](/how-to/send-bulk-whatsapp-from-excel)

Will my number get banned for sending bulk messages on the API?+

Bulk messaging is what the API is for. Numbers get limited when many people block or report them, so message only opted-in customers with relevant messages.

Do customers need to save my number?+

No — with the API, approved template messages reach opted-in customers whether or not they saved your number.

How much does it cost?+

Meta charges per message by category — about ₹0.86 for marketing and ₹0.115 for utility in India (excluding GST). Lead Pattern passes these through at cost; plans are separate. [Pricing →](/pricing)

Is there a free bulk WhatsApp sender?+

Official sending always has Meta's per-message charge. Lead Pattern sets up the API for free and offers a 14-day free trial on the Growth plan.
