stillmail.

Product Introduction

1. Definition: stillmail is a digital correspondence platform (SaaS category) that simulates traditional letter-writing. It enables users to compose, format, and send stylized digital letters mimicking physical stationery.
2. Core Value Proposition: It solves digital communication fatigue by promoting mindful, heartfelt correspondence through customizable tactile elements, targeting users seeking meaningful connections beyond instant messaging.

Main Features

1. Customizable Stationery Design:

   • How it works: Users select paper texture (e.g., linen, parchment), ink color (hex-code supported), and envelope designs via a CSS-powered editor. Output renders as a responsive HTML email.
   • Technology: Vector-based SVG for scalable stationery elements, coupled with CSS filters for texture simulation.

2. Analog Writing Simulation:

   • How it works: Typing animations replicate fountain-pen ink flow, with adjustable "drying time" to discourage rushed drafting. Auto-saves drafts to cloud storage (Firebase backend).
   • Technology: Canvas API for real-time ink rendering and WebSockets for draft synchronization.

3. Asynchronous Delivery Scheduling:

   • How it works: Letters are queued for 24-72 hour delivery, emulating postal delays. Recipients receive a curated email with interactive stationery.
   • Technology: Node.js cron jobs for timed delivery and Postmark API for email rendering.

Problems Solved

1. Pain Point: Replaces impersonal digital chats with emotionally resonant communication, countering notification fatigue and superficial interactions.
2. Target Audience:
   • Nostalgia enthusiasts (35-65 age group)
   • Therapists using written reflection exercises
   • Long-distance couples seeking romantic gestures
   • Educators teaching epistolary writing
3. Use Cases:
   • Sending condolence letters with muted ink/paper tones
   • Creating vintage-style wedding invitations
   • Journaling with self-addressed future letters

Unique Advantages

1. Differentiation: Unlike email clients (Gmail, Outlook) or card-sending services (Paperless Post), stillmail focuses exclusively on replicating the sensory ritual of handwriting—no templates, only bespoke stationery.
2. Key Innovation: Patented "Ink Physics Engine" dynamically adjusts letter opacity/spacing based on typing speed, authentically mimicking fountain-pen behavior unavailable in competitors.
