# How Bulk WhatsApp Messaging Works

Bulk WhatsApp Messaging uses approved WhatsApp templates, your customer list (uploaded or selected), and your Wallet balance to deliver messages through the WhatsApp Cloud API.\
Picky Assist handles the delivery, tracking, and reporting.

***

### Bulk Messaging Flow

Bulk messaging works through the following core steps:

* You select an **approved WhatsApp template**.
* You upload or select your **customer list** with correct country codes.
* Picky Assist sends the template to all recipients via the official **WhatsApp Cloud API**.
* Meta charges per message and deducts the amount from your **Picky Assist Wallet**.
* Delivery, read, and failure reports are updated in your dashboard automatically.

This makes large-scale customer communication fast, structured, and compliant with WhatsApp policies.

***

### WhatsApp Sending Limits

WhatsApp controls how many customers you can message per day.\
Sending limits are tied to **business verification** and **message quality**.

### **If Business Is Not Verified**

* You can send **only 250 messages/day** (combined total).
* Verification is required for scaling bulk communication.

### **After Business Verification**

Updated WhatsApp limits:

* **Tier 1** → 2,000 messages/day
* **Tier 2** → 10,000 messages/day
* **Tier 3** → 100,000 messages/day
* **Tier 4** → Unlimited

***

### Wallet Balance Requirement

Bulk messaging works only if your **Picky Assist Wallet** has enough balance.\
Each message consumes an amount based on:

* Recipient country
* Template category (Marketing/Utility/Authentication)

No minimum recharge required — just ensure your balance can cover the total messages you plan to send.

Sending bulk messages to customers who do not know your business can reduce your WhatsApp Quality Rating and may lead to restrictions.

### Best Practices to Improve Delivery & Engagement in Bulk WhatsApp Messaging

* Use **WhatsApp-approved templates** that provide real value, not excessive promotions
* Send messages during **active customer hours** for better open and response rates
* Keep messages **short, clear, and purpose-driven**
* Always **double-check country codes** before sending bulk messages
* Avoid sending bulk campaigns too frequently to **prevent spam reports and quality issues**
