The challenge.
The organization needed to organize donor records and campaign communication instead of managing them through personal accounts and spreadsheets.
- Personal WhatsApp accounts at risk of ban for bulk messaging
- No donor CRM — contacts in spreadsheets, no history
- Campaign performance invisible — no open rates, no response tracking
- Donation receipts sent manually, days late
Decisions behind the build.
WhatsApp Business messaging requires approved templates and rate-aware sending. I used a queue-based architecture with BullMQ and Redis to coordinate campaigns.
Queue-Based Messaging
BullMQ and Redis coordinate dispatch so campaigns can be paced around API limits.
Template Management
Dashboard for creating, submitting, and tracking Meta template approvals. Approved templates are available for campaigns immediately.
Donor CRM
Full donor profiles with donation history, campaign engagement, and communication logs. Segment donors by amount, recency, or campaign participation.
Receipt Workflow
Donation events can trigger WhatsApp acknowledgments through the messaging queue.
