# Resend

> Extracted from [https://resend.com/](https://resend.com/) on 2026-11-12 by Emblematic. Every value below was read from the rendered DOM (computed styles, `document.fonts`, and the fonts Chrome actually used to paint text), not estimated from pixels. When the YAML front matter and this prose disagree, the YAML wins. Copy values from this file exactly; don't transcribe them from memory. Don't copy logos, imagery, illustrations or marketing copy.

## Overview

Resend uses a dark canvas (#000000) with a palette. Type is set in **Inter**, **ABC Favorit** (display), **Commit Mono** (mono), with 18px body text. Layout: 1280px container, top-sticky+transparent navigation, 15 sections. Built with next.js, tailwind, mintlify, posthog, vercel.

## Colors

Area-weighted from painted backgrounds, text and borders on the 1440px light capture. Roles are inferred from usage (largest background, most text, interactive fills). Every hex is an exact computed value; a role marked *unverified* is a best guess that has not passed review, so its canonical token (e.g. `primary`) is left out of the front matter.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |
|---|---|---|---|---|---|
| `background` | `#000000` | 0 0 0 | bg | 88.9% | `--bg-base` |

Sparse chromatic highlights (not accents): `#FFCA16` (`--amber-a11`), `#46FEA5D4` (`--green-a11`).

Contrast: text on background 21:1, muted text 8.37:1.

Gradients in use: `linear-gradient(rgba(0, 0, 0, 0) 60%, rgb(0, 0, 0) 100%, rgb(0, 0, 0) 100%)`; `linear-gradient(rgba(0, 0, 0, 0) 0%, rgb(0, 0, 0) 50%, rgb(0, 0, 0) 100%)`.

The site does not change under `prefers-color-scheme: dark`.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** (CSS: `Inter Website`) | body | 400, 500, 600 | 44.0% | webfont |
| **ABC Favorit** (CSS: `aBCFavorit`) | display | 400 | 26.0% | webfont |
| **Commit Mono** (CSS: `Commit Mono Website`) | mono | 400 | 17.0% | webfont |
| **Domaine** (CSS: `domaine`) | other | 400 | 11.4% | webfont |
| **Helvetica** | other | 400, 600, 700 | 1.7% | system (stack `Helvetica`, resolved on macos) |

Declared in `@font-face` but not used to paint text on this page: Lateral Variable. Don't treat these as the page's fonts.

Scale (px): 12, 14, 16, 18, 20, 24, 56, 77, 96. Effective ratio ≈ 1.398 (close to a augmented fourth). Body 18px at line-height 1.5; display 96px with tracking -0.01em. Headings are sentence case. On a 390px viewport the body is 16px and display 64px.

## Layout

Spacing has no reliable single base unit; the most used steps are 2, 4, 6, 8, 12, 14, 16, 20, 24, 32, 48, 80, 96px. Sections open with about 192px of space before their first line of text. Content sits in a 1280px container on a 6-column grid. Text density 0.094 (text area / page area).

Section order (desktop). Kinds below the review threshold are shown as *section*:

1. **nav** (58px, bg #000000)
2. **section** (58px, bg #000000)
3. **hero** — “Email for developers” (900px, bg #000000)
4. **logos** (647px, bg #000000)
5. **section** — “Integrate” (1200px, bg #000000)
6. **section** — “Modular webhooks” (1063px, bg #000000)
7. **section** — “Write using a delightful editor” (1262px, bg #000000)
8. **section** — “Broadcast analytics” (995px, bg #000000)
9. **section** — “Develop emails using React” (491px, bg #000000)
10. **section** — “Welcome to , user!” (780px, bg #000000)
11. **section** — “Prevent spoofing with DMARC” (1668px, bg #000000)
12. **section** — “Everything in your control” (1256px, bg #000000)
13. **testimonials** — “Beyond expectations” (781px, bg #000000)
14. **section** — “Email reimagined. Available today.” (702px, bg #000000)
15. **footer** (637px, bg #000000)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`
- `rgb(255, 255, 255) 0px 1px 1px 0px inset`

## Shapes

Dominant corner radius 16px; radii in use: 4px, 6px, 8px, 10px, 16px, 24px, pill. Borders: hairline (1px).

## Components

- **card**: rounded `24px`, padding `0px`, border `1px solid #D6EBFD30`

## Do's and Don'ts

- Do set body copy in Inter at 18px / 1.5.
- Do use ABC Favorit only for display sizes, not for body text.
- Do tighten large headlines (-0.01em at 96px).
- Don't introduce font weights beyond 400, 500, 600, 700.
- Do keep corners at 16px for most controls, and use the larger radii only for cards and media.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
