Client: Plaxic (Environmental Technology Platform)

Primary Tools: HubSpot, Custom SMTP Infrastructure, HTML/CSS, Handlebars/Liquid 

The Objective

Plaxic operates a multi-sided platform with three distinct user groups — donors, project owners, and cleanup contributors — each interacting with the system for entirely different reasons. As the platform scaled, email became critical infrastructure: account security, financial trust, project coordination, and ongoing participation all depended on the right message reaching the right person at exactly the right moment. The challenge wasn't just sending more emails — it was designing a CRM and communication architecture that could cleanly separate three personas, handle high-trust financial workflows, and trigger the right message automatically without adding manual overhead for the team. 

Event-Driven Lifecycle Design 

I started by defining clear lifecycle entry points for each user type. From the moment someone joined the platform, the CRM immediately identified whether they were a donor, worker, or project manager and routed them into the appropriate communication path.

This ensured users only received information that matched their role, while maintaining a consistent and professional brand experience — especially important for a platform handling money.

Transactional Integrity & SMTP Security Operations 

Once users began interacting financially with the platform, clarity and reassurance became critical. I designed transactional emails that focused on transparency, clearly showing amounts, timing, and purpose, while still reinforcing Plaxic’s mission.

Dynamic content pulled live transaction details directly into the emails, reducing confusion and support requests while helping users feel confident their money was handled correctly.

Closing the Loop Between Donors & Projects

A major focus was ensuring contributors and project owners stayed informed as projects progressed. Instead of manual updates, the CRM listened for project status changes and triggered timely, relevant notifications automatically.

Donors could see when their support moved a project forward, while project owners received instant confirmation when funding activity occurred — keeping everyone aligned without extra effort from the team.

Work-to-Wallet Lifecycle for Cleanup Crews

For cleanup workers, speed and clarity mattered most. I built a simple work-to-wallet communication loop that guided workers from project completion through payout, using mobile-friendly designs that were easy to scan in active environments.

Instructional emails explained next steps, while payout confirmations provided immediate reassurance once funds were withdrawn.

Strategic Impact & Key Results

Operational automation: Eliminated manual coordination for transactional and project-status communications

Higher retention: Increased recurring participation by 22% through timely, behavior-based updates

Stronger trust: Reduced payment-related support requests by delivering clear, real-time confirmations

Reliable delivery: Maintained 99%+ deliverability and consistently high open rates through clean data and role-based messaging

By structuring Plaxic’s CRM around clear personas, secure transactional messaging, and event-based automation, email and CRM became a reliable operating system for the platform — not just a broadcast channel. The result was a scalable communication framework that supported trust, participation, and growth without adding complexity.

This project sits at the intersection of technical email infrastructure and product-level CRM design — the kind of work that only matters if it's airtight. Building role-based routing, dynamic transactional content with Handlebars/Liquid, and a secure SMTP layer for a platform handling real money required thinking like both an engineer and a communicator. If your platform has multiple user types, complex lifecycle triggers, or high-stakes transactional email that needs to be reliable at scale, Let’s connect on LinkedIn.
