What the Envelope Open icon means and where it's used, then how to install, style, label and license it.
The envelope-open icon represents opened emails and read messages with its distinctive open envelope design. This universal symbol has become the standard indicator for read email status, opened messages, email viewing, and message read states across modern email clients and messaging applications.
In modern applications like Gmail's read email indicators or inbox interfaces showing message status, you'll see this open envelope indicating read messages, opened emails, and viewed correspondence. It appears in email lists where read status differentiation, or in notification systems like those in Slack where read message states require clear visual indicators.
From an email management perspective, the open envelope design communicates more than simple reading - it specifically indicates read email status, opened message states, and the viewed nature of correspondence. This visual distinction helps users differentiate between unread and read messages in inbox interfaces.
Envelope Open is one of 1,288 icons in HeroIcons, made by Refactoring UI Inc and released under MIT. It is drawn on a 24 × 24 grid with a 1.5 stroke.
Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds EnvelopeOpenIcon to components/icons/heroicons-envelope-open.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.
Copy it as React (from Get icon, or the Code section): a typed EnvelopeOpenIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.
Yes, if your project has @heroicons/react/24/outline: Envelope Open is `EnvelopeOpenIcon` there, used as <EnvelopeOpenIcon />. The shadcn.io MCP server answers with that import when it finds the package. Without it, copy the icon from here.
Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.
With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Envelope Open icon, or any of 1,288 HeroIcons icons, and install it from a prompt.
It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.
Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.
Envelope Open is a line icon drawn with a stroke width of 1.5. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.
Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.
Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Envelope Open", so screen readers say what it does.
Yes. EnvelopeOpenIcon passes every SVG prop to the svg element, so <EnvelopeOpenIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.
Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.
Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.
No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming HeroIcons, Refactoring UI Inc and the license.
Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
