Enterprise WhatsApp Campaign Platform
Hospitals were sending appointment reminders and health campaigns manually over personal WhatsApp — slow, un-trackable, and against WhatsApp Business policies.
1The Problem
No centralized way to send broadcasts at scale, manage approved templates, automate follow-ups, or measure campaign performance. Manual sending consumed hours of staff time every single day.
2The Solution
I built a campaign platform on the WhatsApp Business API: a template approval workflow, segmented broadcast sending with rate-limit handling, automated follow-up sequences, and a dashboard tracking delivered, read, and replied metrics for every campaign.
3The Architecture
Campaign managers build audiences and flows once; a rate-limited queue delivers them through the WhatsApp Business API, with delivery and reply metrics flowing back.
Compliant Broadcast Platform
4The Results
- 10,000+ messages delivered per day without blocking
- Appointment no-shows reduced by 25% via automated reminders
- Campaign reply rate up from ~8% to 22% with follow-ups
- Full audit trail and per-campaign analytics
