Problem Solved

Organizations running campaigns across teams needed stronger control over sending domains, message quality, recipient handling, and deliverability feedback, but existing tools did not fit multi-tenant governance needs. This created risk around sender trust, inconsistent campaign operations, and limited visibility into what was actually performing.

How I Solved It

I built a full-stack multi-tenant platform that combines domain verification, campaign orchestration, recipient pipelines, and engagement tracking in one operational system. The architecture emphasizes controlled sending workflows and analytics visibility so teams can execute at scale without losing governance and reliability — engineered to push 10K+ recipients per campaign with no daily send cap, backed by a 99.9% uptime target.

Key Features Delivered

  • Multi tenant organization model with scoped resources and teams.
  • Campaign lifecycle from draft to schedule/send with status controls.
  • Domain verification and sender identity management.
  • Recipient import and template workflows with variable support.
  • Open/click tracking and analytics surfaces for campaign decisions.

What Can Be Done Next

  • Live — Email campaigns with verified domain sending, recipient pipelines, and engagement analytics.
  • In staging — WhatsApp delivery module for cross channel messaging.
  • Planned — SMS and voice channels, deeper audience segmentation and lifecycle automation, expanded deliverability diagnostics and inbox placement insights, and stronger org level policy and compliance controls.
