Design Context

Users

Developer-founders and indie hackers building SaaS products. They use Plunk to handle transactional and marketing email without the complexity of tools like Mailchimp or Customer.io. They notice tiny details — inconsistent spacing, placeholder text that adds no value, a button that doesn't communicate state. Context: professional environment, desktop-first.

Brand Personality

Sharp, minimal, confident. The product earns trust by being simple and correct, not by being flashy. Testimonials emphasize "transparent UI", "easy setup", "clean design" — the brand is care without noise.

Aesthetic Direction

Light mode only. Palette: black (neutral-900), neutral grays, white. No accent colors. No color for decoration — only for semantics (red = error, green = success). Backgrounds are near-white with subtle texture. Cards use white with a neutral border and light shadow. Typography should feel precise and legible, not editorial. Spacing should feel considered, not generous.

Design Principles

  1. Every pixel earns its place. If something doesn't communicate information or provide affordance, remove it.
  2. Neutral by default, semantic by exception. Color is reserved for error/success/warning states, not decoration.
  3. Interaction should feel fast. Loading states communicate exactly what's happening. No silent actions.
  4. Developer-grade precision. Copy is short and direct. Placeholders only appear when they add value. Labels are unambiguous.
  5. Consistency is trust. The same pattern everywhere. One way to show errors. One way to show success. No creative variation in functional UI.
