Frequently asked questions
Can InboxUnion change or send my mail?
No. InboxUnion requests read-only Gmail access. It cannot send, edit, archive, label, or delete messages.
Which accounts can I connect?
You may connect Google accounts that you own or are expressly authorized to access. Each account is authorized separately on Google's OAuth screen.
Why has a new message not appeared yet?
Use Sync now in the app. If the message still does not appear, contact support with the visible error and approximate time; do not include message content or credentials.
Does InboxUnion download attachments?
Normal synchronization records attachment names, media types, and sizes, but does not download attachment bodies.
How do I remove an account?
Use Disconnect next to the account in InboxUnion, then follow the Data Deletion Instructions to revoke future Google access.
