Bring back Inbox Bundles for Gmail.
Auto-group your email by label into tidy, collapsible bundles — plus more ways to organize your inbox. Free & open source.
Available for Chrome and Firefox — or install from source on GitHub.
Your inbox, bundled
Related email grouped into tidy, collapsible bundles — in light and dark.
Organize your inbox, your way
Everything you loved about Google Inbox bundles — and a few things it never had.
Label bundles
Emails sharing a Gmail label are grouped into one collapsible bundle in your inbox.
Combine labels
Bundle each distinct set of labels together — threads labeled A + B form their own bundle, separate from just A.
Custom bundles
Select any messages and bundle them on the fly — no Gmail label required. They sync across your signed-in Chrome browsers.
Priority bundles
Force chosen labels (or label sets) to always group together, with subtree wildcards and first-match-wins rules.
Sender bundles
Unlabeled mail that shares a sender groups by domain (or exact address on gmail.com & friends). Labels, priority, and custom still win.
Keep starred messages outside bundles
Inbox-style pinning — a starred message stays in its own row, outside the bundle. Toggle under Options → Bundle setup.
Remember the open bundle
Reload, refresh, or bounce through Inbox — the bundle you had open comes back (per tab/page, for the session).
Bundle bulk actions
Select-all, archive-all, snooze-all, or delete/trash-all from the bundle row. Each control uses Gmail’s own toolbar actions on every thread in the bundle. Toggle individually under Options → Features.
Master switch
Pause bundling without disabling the extension — the same “Bundle my inbox” switch in Gmail’s search bar, Options, and the toolbar popup.
All inbox types
Bundles Default, Important/Unread/Starred first, Priority Inbox, and Multiple Inboxes — each visible section independently.
Label colors
Tint bundles to match their Gmail label color — a subtle background fill or an accent bar, both theme-aware.
Light & dark
Follows your Gmail theme, with careful, readable colors in both light and dark modes.
Options autosave
No Save button. Change a setting and it’s stored; new defaults reach installs that never touched that option.
Sync & backup
Options and custom bundles sync across your signed-in browsers. Export or import JSON under Options → Sync & backup when you need a hand-off.
Private by design
Runs entirely in your browser. No accounts, no tracking — your email never leaves your Google session.
Frequently asked
Is Inbundly free?
Yes. Inbundly is free and open source under the GPL-3.0 license. You can read and build the full source on GitHub.
How do I install it?
Add it from the Chrome Web Store or Firefox Add-ons. Prefer to build from source? Clone the GitHub repo, run npm install && npm run build, and load dist/ as an unpacked extension.
Does Inbundly read or send my email?
No. Inbundly only restructures how your inbox is displayed, in your browser. It doesn't send your email anywhere, has no server, and requires no account. See the privacy policy.
Is this the same as Google Inbox?
Inbundly recreates the bundles feature from Google Inbox (discontinued in 2019) inside Gmail. It's an independent, community-maintained project — a rebranded fork of the open-source inboxy by Teresa Ou.
