A system designed to improve how emails are tracked, organised, and understood across workflows.

Overview

Circle Mail is an email-focused system aimed at improving visibility, tracking, and organisation of communication.

It focuses on bridging the gap between sending emails and understanding what happens after — including delivery, interaction, and response behaviour.

Purpose

  • Track email interactions and engagement
  • Improve visibility across communication workflows
  • Link conversations to specific users or actions
  • Reduce reliance on fragmented inbox-based tracking

What I’m Building

  • Email routing and logging systems
  • Identifier-based email tracking (e.g. tagged addresses)
  • Interaction tracking (opens, clicks, behaviour where possible)
  • Integration with internal systems and databases

Technology

  • Email Infrastructure: :contentReference[oaicite:0]{index=0} Email Routing, :contentReference[oaicite:1]{index=1} Mail
  • Sending: :contentReference[oaicite:2]{index=2}
  • Backend: Node.js, database logging systems
  • Tracking: Custom analytics and identifiers

Current Status

  • Stage: Building
  • Focus: Reliability and data capture

Current Work

  • Implementing email routing and logging
  • Structuring identifier-based tracking (e.g. example+id@domain.com)
  • Exploring interaction tracking methods
  • Integrating with internal systems

What This Demonstrates

  • Understanding of email infrastructure and flow
  • Ability to design tracking and analytics systems
  • Integration between multiple services
  • Focus on real-world communication workflows

Future Direction

  • Expand tracking capabilities (clicks, engagement signals)
  • Build a dashboard for visualising communication data
  • Improve reliability and redundancy
  • Potential transition into a standalone tool or SaaS platform

Notes

Circle Mail is designed to solve a practical problem: understanding communication beyond the inbox, and turning email into a measurable, trackable system.
