## Overview

WhatsApp enforces limits and policies to fight spam. Respecting sending pace, list quality and content
greatly reduces the risk of the number being banned.

## Prerequisites

- A connected WhatsApp number.

## Step by step

1. **Warm up** new numbers: start with low volume and increase gradually.
2. **Send to people who opted in**; avoid purchased lists.
3. **Personalize** messages; avoid the exact same text in bulk.
4. **Control the pace** of sends; avoid sudden spikes.
5. **Monitor** replies and blocks; reduce volume if there are risk signs.

## Settings & options

- **Send control**: the platform helps moderate the outbound pace per inbox.
- **Campaigns**: use approved templates and variables to personalize.

## Use cases

- Run a WhatsApp campaign without harming the number's health.
- Keep consistent follow-ups without abusive bursts.

## Tips, limits & best practices

- Prefer quality over volume: engaged lists convert more and risk less.
- Offer an easy opt-out and respect those who ask not to receive.
- For WhatsApp Cloud, follow Meta's approved categories and templates.

## Troubleshooting

- **Number blocked/temporarily banned**: reduce volume, review the list and content, and wait.
- **Many complaints/blocks**: revisit targeting and frequency.
