# Inbox
URL: https://usememos.com/docs/usage/inbox

The inbox is your notification center for collaboration activity. It collects events that involve you so you don't have to revisit memos to find replies.

## What shows up [#what-shows-up]

The inbox surfaces two kinds of notifications:

* **Comments** — someone commented on one of your memos
* **Mentions** — someone mentioned you with `@` in a memo or comment

Each row shows the sender, what they did, a snippet of the relevant content, and a timestamp. The inbox icon in the navigation rail carries an unread-count badge so new activity is visible from anywhere in the app.

## Reading and filtering [#reading-and-filtering]

Open the inbox to see notifications newest-first. A tab bar filters the list:

* **All** — every notification
* **Unread** — notifications you haven't opened yet
* **Archived** — notifications you've cleared

Clicking a notification opens the related memo or comment and marks the notification read.

## Managing notifications [#managing-notifications]

* **Archive** an unread notification to clear it without opening the memo
* **Delete** a read or archived notification to remove it permanently
* notifications that can no longer resolve their memo show a "failed to load" row that you can delete

## Good habits [#good-habits]

* skim **Unread** regularly so mentions and comments don't pile up
* archive notifications once you've acted on them to keep the list focused
* pair the inbox with [reactions and comments](/docs/usage/reactions-comments) as your main collaboration loop
