About this icon

Use the Markunread Mailbox icon

Icons in the fill style — like Markunread Mailbox — are designed for interface components and product UI. Use it across messaging apps, email clients, contact forms, notification systems, CRM dashboards, and live chat widgets for a consistent, professional look.

IconStash's editor lets you fine-tune color, size, and stroke width in real time, then export in the format that fits your workflow: SVG, PNG, JSX, or CSS background-mask.

Export formats

Copy clean SVG vectors with one click, generate custom-size PNG files from 16px to 512px, export JSX/React components ready to paste into your project, or use the icon as a CSS background-mask for flexible theming.

All exports are based on the same editable vector — so the Markunread Mailbox icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Markunread Mailbox comes from Google's Material Design icon set, which ships five coordinated themes: Outlined, Rounded, Sharp, Two Tone and Filled. Outlined is the default for dense UI, Filled reads better for selected or active states, and all five share identical geometry — so you can swap themes without shifting your layout by a pixel.

UX best practices

In messaging, contact and notification UI, the Markunread Mailbox icon should help users triage at a glance. Keep any unread badge small and anchored to the top-right corner, and never rely on the badge alone — expose the count in the accessible name so screen-reader users get the same signal.

Use in your project

React / npm — Material Design Icons
