Post excerpt:
Mailbox providers are tightening up sender requirements for authentication, making DMARC crucial for bulk sending. I made a DMARC validator where you can check out whether your setup is valid or needs any improvements. It looks up _dmarc.<domain>, parses the TXT record, and displays policy (p/sp), alignment (adkim/aspf), reporting (rua/ruf), and options like

# Design Brief: Enterprise Clean (with Soft & Friendly)

Trustworthy blue-anchored palette, structured grids, and prominent customer logo walls.

## Design Tokens

```css
:root {
  --background: #f8fafc;
  --surface: #ffffff;
  --foreground: #173452;
  --muted-foreground: #71849a;
  --accent: #0798e8;
  --radius: 4px;
  --font-heading: "Georgia", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #F8FAFC (~67%) · Surface #FFFFFF (~15%) · Text #173452 (~9%) · Muted Text #71849A (~6%) · Accent #0798E8 (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + CTA
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Pain Relief & Replacement
- Hero components: Custom Illustration, Metrics Strip
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and stacked avatars & testimonials.
- Visual summary: Enterprise Clean (Light canvas, balanced density) featuring centered headline + cta layout and illustration / character art visuals.

## Avoid

- Experimental navigation patterns
- Low-legibility decorative fonts
- Visual novelty that obscures the value proposition

Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
