FAQ
Frequently asked questions
What the Mail Warning icon means and where it's used, then how to install, style, label and license it.
This icon indicates email security alerts and message warnings in communication and cybersecurity applications. Featuring an envelope with an exclamation mark overlay, this symbol has become the critical indicator for suspicious messages, security threats, and potentially dangerous email content across email platforms and security systems.
In modern applications like Microsoft Defender or email security solutions such as Proofpoint and Mimecast, users encounter this icon when emails are flagged for potential threats or security concerns. Popular email platforms including Gmail's security warnings and corporate email systems display this symbol when messages require caution due to phishing attempts, malware attachments, or suspicious sender behavior.
The warning overlay communicates more than just "problematic email" - it specifically indicates active security threats, the need for immediate user attention, and the potential for significant security consequences if the message is mishandled. This distinction helps users understand they're viewing potentially dangerous content rather than simple delivery issues or formatting problems.
Mail Warning is one of 1,655 icons in Lucide, made by Lucide Contributors and released under ISC. It is drawn on a 24 × 24 grid with a 2 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 MailWarningIcon to components/icons/lucide-mail-warning.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 MailWarningIcon 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 lucide-react: Mail Warning is `MailWarningIcon` there, used as <MailWarningIcon />. 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 Mail Warning icon, or any of 1,655 Lucide 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.
Mail Warning is a line icon drawn with a stroke width of 2. 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="Mail Warning", so screen readers say what it does.
Yes. MailWarningIcon passes every SVG prop to the svg element, so <MailWarningIcon 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. ISC 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: ISC 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 Lucide, Lucide Contributors and the license.
Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
Its tags are security, warning, alert, email, danger and caution. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Mail Warning in another set.
