Send WhatsApp messages at scale,
from your regular account.
There are three ways to send WhatsApp messages professionally: the WhatsApp Business app by hand, Meta's official API, or our REST API. Here's the real difference - and why sending your WhatsApp messages from your regular account, with no business account or templates, changes everything.
The context
How do you send WhatsApp messages to multiple contacts?
To send WhatsApp messages professionally, most people start with the WhatsApp Business app - free, but designed for small manual volumes, not for sending at scale.
The WhatsApp Business app is perfect for replying to customers one by one. But as soon as it comes to sending the same WhatsApp message to hundreds of people, it shows its limits: broadcast lists cap at 256 contacts, and each recipient must have saved your number in their address book to receive the message. No automation, no API: everything is done by hand, from the phone.
The second route is Meta's official WhatsApp Business API (Cloud API). Powerful, but demanding: you need a verified Meta Business account, a dedicated number, every message template approved by Meta, and you have to accept per-conversation billing that varies by country and category. To send a simple automated WhatsApp message, it's a real integration project.
The third route is Unlimited Messaging: a REST API that sends your WhatsApp messages from your regular account. No business account to create, no template to approve, no per-conversation billing. You link your existing account, you call the API, and you send WhatsApp messages in bulk - unlimited, ready in minutes, with Python and TypeScript SDKs.
Comparison
WhatsApp Business vs Unlimited Messaging for bulk sending
The same goal - sending WhatsApp messages to many people - with two radically different levels of friction. Here, line by line, is what Meta's app and API require, and how our alternative does without it.
| WhatsApp Business (app + Meta API)official, by hand or via BSP | Unlimited Messagingyour account, via API | |
|---|---|---|
| Getting started | Days to weeks (Meta verification) | A few minutes |
| Account required | Verified Meta Business account | Your regular WhatsApp account |
| Automation / API | None in the app; API restricted to verified accounts | Full REST API, from the start |
| Volume | 256 contacts per broadcast list | Unlimited |
| Templates | Mandatory Meta approval (API) | No approval, free-form text |
| Pricing | Per conversation, varies by country | Flat monthly price, unlimited |
| Media | Manual in the app; via templates in the API | Images, PDFs and videos by URL |
| SDK | Depends on the BSP | Official Python & TypeScript |
Our approach
Send WhatsApp messages in bulk, from your regular account
We keep the simplicity of an ordinary WhatsApp account, and add the power of an API - without any of Meta's constraints.
Your regular WhatsApp account
You link the account you already use, by scanning a QR code like WhatsApp Web. No business account to create, no dedicated number, no business verification with Meta.
Beyond the 256 contacts
Forget the broadcast list limit: send the same WhatsApp message to as many recipients as you want, without them having to save your number.
Automated WhatsApp messages
A POST to the API and the message goes out. Wire your reminders, notifications and campaigns to code - no more sending by hand from the phone.
Zero templates to approve
You write the message you want, whenever you want. No Meta approval, no per-conversation billing: a flat price, unlimited sends.
