Email Platform Lab

Email Platform Lab

A complete email engineering lab with handcrafted templates, an approval portal, and a visual block builder.

Email Platform Lab

Project Summary

Email Platform Lab is a production-style email platform I built end-to-end to showcase advanced email templating and campaign operations.
The project evolved from a static template exercise into a complete workflow system with rendering safeguards, QA checkpoints, and internal tooling for campaign approvals.

Why I Built It

I wanted a portfolio project that proves practical delivery, not just UI polish.
Email is a high-friction channel where small HTML/CSS mistakes can break business-critical communication, so I built this lab to demonstrate:

  • robust responsive email template development;
  • cross-client compatibility engineering;
  • workflow automation for marketing operations;
  • maintainable architecture for fast iteration.

Platform Structure

1) Email Lab (apps/email-lab)

  • Handcrafted HTML templates for newsletter, promo, and transactional use cases.
  • Component-style partials (header, button, footer) with token hydration.
  • Build pipeline that sanitizes output, compiles templates, and generates a preview index.
  • Payload size tracking to avoid Gmail clipping and improve deliverability readiness.

2) Growth Admin Portal (apps/admin-portal)

  • React + TypeScript interface to manage campaign status and review flow.
  • Zustand state model with guarded transitions:
    • Draft -> In Review -> Approved/Rejected
  • Role-based permissions and audit events for traceability.
  • QA and content validation before approval to reduce publishing errors.

3) Visual Email Builder (apps/email-builder)

  • Next.js + React drag-and-drop editor with @dnd-kit.
  • Block-based composition for reusable email sections.
  • Inspector controls for spacing, typography, and content overrides.
  • JSON import/export to bridge visual prototyping and production templates.

Technical Decisions and Solutions

  • Implemented bulletproof CTA behavior with Outlook VML fallback and standard links for modern clients.
  • Added sanitization rules to normalize problematic markup patterns and reduce rendering regressions.
  • Included dark mode resilience patterns to handle forced inversion and logo swapping safely.
  • Created accessibility/localization test templates to validate long text, RTL, and semantic structure.
  • Built a realistic QA checklist around Apple Mail, Gmail, Outlook, and Yahoo behavior.

Build Timeline (from Git History)

  1. 2026-02-09: initial scaffold of the course-driven email lab and admin workflow.
  2. 2026-02-22: launch of the visual email builder and expanded documentation.
  3. 2026-02-23: naming and structural refinements after stabilization.

Freelancer-Relevant Outcomes
