Mails – Enterprise Email & Communication Platform
A French enterprise client needed a complete email ecosystem — from inbox management to team collaboration — delivered in 48 hours. SoftGen accepted the challenge and shipped a production-ready platform that now handles 1,200+ daily emails across their entire organization.
“This project is SoftGen's most extreme proof of execution speed. A France-based enterprise client — whose identity remains confidential under NDA — reached out on a Tuesday evening with an urgent requirement: their existing email infrastructure was being deprecated by their provider, and they needed a fully functional, branded email management platform operational by Thursday morning (Paris time). Not a prototype. Not an MVP. A production-ready system that 40+ employees would use daily. SoftGen's senior engineering team accepted the 48-hour challenge — and delivered 2 hours ahead of deadline.”

How we identified the core bottleneck and engineered a precision solution.
The Challenge
What the client was struggling with
The client's existing email provider announced an abrupt service termination, giving the organization less than 72 hours to migrate their entire communication infrastructure. With 40+ employees relying on email for daily operations — client correspondence, internal coordination, compliance documentation — any downtime meant direct revenue loss. The requirements were non-negotiable: full inbox management (compose, reply, forward, attachments), folder organization with labels, multi-tab interface for parallel email handling, search functionality across 50,000+ archived messages, and mobile responsiveness for field teams. All within 48 hours.
Our Solution
How SoftGen solved it
SoftGen mobilized a focused 2-person engineering sprint. We chose Next.js + Supabase for maximum development velocity without sacrificing production quality. The architecture decision was deliberate: Supabase's real-time subscriptions meant new emails appear instantly without polling, PostgreSQL's full-text search handles the 50K+ message archive with sub-200ms query times, and Row Level Security ensures each employee only accesses their own mailbox — even at the database level. We shipped the complete platform in 46 hours — 2 hours ahead of the client's Thursday morning deadline in Paris.
Core Architecture & Features
The foundational systems engineered to solve complex domain problems.
Full-Featured Inbox Engine
Complete email management — compose with rich text editor, reply/forward threading, attachment handling (up to 25MB), draft auto-save, and read/unread tracking. Supports CC/BCC, email signatures, and scheduled sending. Built to handle 1,200+ daily emails across the organization.
