Meta is working on a dedicated Mail tab for its Muse agent, which would open a separate page and give the agent its own mailbox. We spotted the unreleased interface, which suggests users could review Muse’s email conversations in one place.

The exact functionality remains unclear. Muse could receive its own email address and handle correspondence on its own behalf. Alternatively, the tab could aggregate communication managed through users’ connected personal accounts, which Muse can already access with authorization. A separate mailbox seems the more plausible interpretation, but the interface alone does not confirm it.

The feature could become particularly useful alongside Meta’s upcoming Shared Agents functionality. Shared Agents would let users configure agents for their businesses and share them as reusable templates. Giving those agents dedicated mailboxes could provide a practical channel for handling business correspondence while keeping the conversations visible to their owners.

Dedicated agent mailboxes are not new, but Muse’s distribution could bring the approach to a wider audience. The app recently reached the top spot on the US App Store, although its availability outside the US remains limited.

a week after launch, muse is now the #1 app in the App Store! it’s been SO exciting to see how much y’all have done with muse. we can’t wait to do more together!

For Meta, the addition would fit Muse’s direction as a personal agent that carries out tasks across connected services. It also follows the recent release of a desktop app with computer-use capabilities.

META: A standalone Muse app for macOS is now available (still US only). Muse for Mac seems to have Computer Use functionality from the start! "Your personal agent can get things done for you directly on your computer (all with your explicit permission)."

There is no confirmed release date for the Mail tab, and whether it will operate independently of connected personal inboxes remains unclear.

Editorial notes

• Meta publicly says Muse can connect to a user's email with selectable read and send access, and that sending email requires approval. This supports the alternative connected-account interpretation but does not establish what the Mail tab will do.
• So far, Meta announced a US rollout on iOS, Android, and muse.ai. The current App Store listing describes email management and connected apps.
