In short: the WhatsApp app limits broadcast lists to 256 contacts, and only people who saved your number receive them. With Monarkz on the WhatsApp Business API, you can broadcast approved template messages to thousands of opted-in contacts, personalised and tracked.
The WhatsApp broadcast limit, explained
In the regular WhatsApp and WhatsApp Business apps, a broadcast list can include up to 256 contacts, and the message is only delivered to people who have saved your number in their phone. That makes app broadcasts impractical for real marketing. Read our full guide to the WhatsApp broadcast list limit.
With the WhatsApp Business API, there is no 256-recipient list cap. Instead, Meta sets a daily messaging limit on the number of unique customers you can start conversations with. New numbers start lower and move up through higher tiers automatically as you send good-quality messages.
Why not use a "WhatsApp blaster" or mass sender app?
Unofficial bulk senders and Chrome extensions automate WhatsApp Web. They break WhatsApp's terms, are easily detected and are a common reason numbers get banned. Monarkz uses Meta's official API, built for business messaging at scale.

Frequently asked questions
How many people can I send a WhatsApp broadcast to?
In the WhatsApp app, up to 256 contacts per broadcast list. On the WhatsApp Business API, Meta sets a daily limit on unique customers per number that rises automatically as you send good-quality messages.
Is bulk WhatsApp messaging legal?
Yes, when recipients have opted in and you follow WhatsApp’s Business and Commerce policies. Sending to purchased or scraped lists is not allowed.
Will my number get banned for bulk messaging?
Unofficial blasting tools carry a high ban risk. Sending approved templates through the official API to opted-in contacts is the compliant way to message at scale.
Do recipients need to save my number?
No. Unlike app broadcast lists, API template messages reach opted-in contacts whether or not they saved your number.
Can I send bulk WhatsApp messages for free?
The Monarkz free trial lets you test broadcasts. Meta charges per template message based on country and category, so large campaigns have a Meta cost.
Can resellers or agencies use Monarkz?
Yes. The Pro plan supports up to 50 WhatsApp accounts and 100 agents, which suits agencies managing several clients.
