How to manage multiple Gmail accounts on a Mac

Start with the two views you actually need

A unified inbox and separate account inboxes solve different problems. The unified view is your triage desk: it shows new work across every connected account. The account view is where context matters, such as using the correct signature, contact list, labels, and sender identity.

The most useful Mac setup makes both views immediate. You should be able to scan everything, then move into a specific account without signing out, opening another browser profile, or waiting for the message list to reload.

• Use All Inboxes to spot urgent work across every address.
• Use account views when replying, searching, labeling, or reviewing sent mail.
• Give each account a recognizable display name while keeping the real email address visible.

Keep Gmail as the source of truth

A multi-account client should not force you to abandon Gmail organization. Archive, Spam, Trash, Sent, Drafts, Starred, categories, and labels should still behave like Gmail. Actions taken on the Mac should remain reflected when you later open Gmail in a browser or on your phone.

This matters most for Google Workspace accounts, where a label or archived conversation may be part of a team process. A unified interface is valuable only when it preserves the underlying Gmail state.

Build one repeatable processing routine

The fastest workflow is consistent: scan, decide, act, and move on. Avoid using the unified inbox as a permanent storage pile. Treat it as the place where messages enter your attention, then archive, label, snooze, reply, or schedule follow-up.

• Scan unread conversations across all accounts.
• Use keyboard navigation or the command center to move quickly.
• Archive completed mail instead of leaving everything in the inbox.
• Snooze work that belongs to a future date.
• Use per-account signatures so the right identity is automatic.

Choose secure account connection

For Gmail and Google Workspace, OAuth is preferable to handing an app your Google password. OAuth lets Google show the requested permissions and gives you a central place to revoke access. On macOS, saved authorization tokens should be protected in Keychain rather than stored as readable preferences.

Unibox connects each Google account separately with OAuth, stores authorization in macOS Keychain, and keeps its message cache, drafts, signatures, and settings on your Mac. Optional AI is off until you provide your own API key and enable it.

Know when a unified inbox is not the right fit

Some people prefer strict separation between work and personal mail. In that case, use account-specific views and notifications rather than an all-account queue. Unibox supports both patterns across Gmail and Google Workspace, Microsoft 365 and Outlook, Yahoo Mail, and standards-based IMAP/SMTP accounts on macOS.
