Filters and labels do not limit access.
By Vamsi Krishna · Updated
No. Filters and labels organize mail inside your account. Access is granted at the account level, so any app or person you allow reads straight past them.
What they actually do
A filter matches incoming mail and applies a label, skips the inbox, or forwards a copy. A label is a tag you can search by. All of it happens inside your account, and none of it changes who may open the account.
Does a label restrict an app?
No. Google publishes no permission scoped to a label, sender, search or date range, so there is nothing for a label to attach to.
Does it restrict a delegate?
No. A delegate sees the mailbox, labels and all.
Then what does limit access?
- The account boundary. Which is why forwarding into a separate account works.
- A filtered view in front of the account. Something else holds the credential and passes on only what matched.
A filter is still the right tool for deciding which mail to share. It just can't enforce that decision.
Where allowemail fits
We scope Gmail for AI tools today. Scoped access for a person is planned, not built. If that is what you need now, use the second account. Early access list.
