Private by design · Read-only access

Every inbox.One calm place.

InboxUnion brings email from multiple accounts you control into one private, searchable inbox—without sending, editing, or deleting messages.

Uses Google's official APIs. You stay in control of every connected account.

A focused workflow

Less inbox switching. No control taken away.

InboxUnion is intentionally read-only. It creates a searchable index for the accounts you authorize while leaving every original message where it belongs.

01

One view across accounts

Bring messages from the accounts you choose into a normalized inbox without changing the originals.

02

Search with context

Find locally indexed messages by sender, subject, date, account, and text, then open the complete thread.

03

Near-real-time updates

Official Gmail push notifications can trigger safe incremental synchronization when new mail arrives.

04

Control every connection

Each account has independent authorization. Disconnecting one removes its credentials and indexed data.

Clear boundaries

Read what you allow. Never act as you.

InboxUnion can

  • Read authorized messages and metadata
  • Build a local searchable index
  • Display threads across connected accounts
  • Synchronize new mailbox changes

InboxUnion cannot

  • Send messages or drafts
  • Edit, archive, label, or delete mail
  • Change Gmail account settings
  • Request or store Google passwords

Privacy in plain language

Your mailbox is not an advertising profile.

InboxUnion uses Google user data only to provide the inbox, search, synchronization, and account-management features you request. It does not sell mailbox data or use it for advertising.
