How to Send Bulk WhatsApp Messages

By App-ening Team · March 2026 · 8 min read

Sending bulk WhatsApp messages is the most effective marketing channel for businesses in Ghana. With a 98% open rate (vs 20% for email), WhatsApp campaigns deliver more engagement per dollar spent.

WhatsApp Broadcast vs Bulk Messaging

The WhatsApp Business App lets you broadcast to 256 contacts — but they must have your number saved. The WhatsApp Business API (via platforms like App-ening) lets you message thousands of contacts regardless, using pre-approved templates.

Step-by-Step: Sending Your First Campaign

Import your contacts via CSV or API. Create segments by tags, custom fields, or behaviour. Design your template message with personalisation variables (name, order number, etc.). Schedule the campaign or send immediately. Monitor delivery, opens, and replies in real time.

Pricing and Costs in Ghana

WhatsApp charges per 24-hour conversation window. Marketing conversations cost more than utility or service conversations. 1,000 free service conversations per month when customers initiate. Platform fees start at $29/month for App-ening.

Compliance and Best Practices

Only message contacts who have opted in. Use approved templates for the first message. Include an opt-out option. Comply with Ghana Data Protection Act, 2012 (Act 843). Segment your audience — relevant messages get better engagement and lower reporting rates.

Measuring Campaign Results

Track delivery rate, read rate, reply rate, and link clicks. Use UTM parameters for website tracking. App-ening provides campaign analytics dashboards with export to CSV.
