However, sending hundreds or thousands of messages manually is inefficient, and doing so incorrectly can lead to account bans or spam flagging.
Benefits of WhatsApp bulk messaging:
- Direct connection to customers
- High open and response rates

Understanding WhatsApp Bulk Messaging

- Limit of 256 contacts per broadcast list.
- Useful for smaller campaigns but insufficient for 1,000+ contacts.
- WhatsApp Business API & CRM Automation:
- Official solution for high-volume messaging.
- Compliant, reliable, and scalable.

- Poor message delivery rates
- Legal issues due to spam complaints
- Damage to brand reputation
Using the official WhatsApp Business API, integrated with a CRM like WhatZCRM, ensures safe, compliant messaging.
