SaaS platform for email deliverability monitoring and optimization powered by AWS SES.

What It Does

Numonic helps SaaS companies and developers monitor, debug, and improve their email deliverability when using AWS SES. It surfaces bounce rates, spam complaints, reputation metrics, and sending statistics in a clean dashboard — without needing to parse CloudWatch or SES raw event streams manually.

Architecture

Built on a fully serverless stack on AWS:

  • AWS SES for email sending and event notifications
  • AWS Lambda for processing SES SNS events (bounces, complaints, deliveries)
  • AWS EventBridge for routing and scheduling
  • Next.js frontend deployed on Vercel
  • NestJS API for business logic and integrations
  • PostgreSQL (RDS) for persistent storage of events and metrics

Key Features

  • Real-time bounce and complaint tracking with severity classification
  • Sender reputation scoring based on SES metrics
  • Email domain health checks and DNS validation
  • Alerting via webhook or email when thresholds are breached
  • Multi-account support for agencies managing multiple SES identities
