Is Clean Mail Hub free?

Yes. Clean Mail Hub is free to install from the Chrome Web Store and all features, including mass unsubscribe, auto-clean rules and the large email finder, are included.

Is Clean Mail Hub safe to use with my Gmail account?

Clean Mail Hub signs in with Google’s official OAuth sign-in, so it never sees your password. It runs entirely inside your browser, reads only email metadata (sender, subject, date, size and labels), never reads email bodies or attachments, and sends no data to any server. You can revoke access at any time from your Google Account permissions page.

Will Clean Mail Hub permanently delete my emails?

No. Every cleanup moves emails to Gmail Trash, where Gmail keeps them for 30 days. You can also undo any cleanup from the History tab with one click.

How do I mass unsubscribe from emails in Gmail?

Open Clean Mail Hub, go to the Unsubscribe tab and click Scan Subscriptions. Sort by “Least read” to find the newsletters you never open, tick the ones you want to stop, and click Unsubscribe. You can also move their old emails to Trash at the same time.

How do I free up Gmail storage space?

Use the Large Emails tab to find messages with big attachments, sorted by size, and move them to Trash. Then empty Gmail Trash to reclaim the space, because Gmail counts emails in Trash towards your storage until they are removed.

Does Clean Mail Hub touch starred or important emails?

No. Auto-clean rules and sender cleanups always skip starred and important emails, as well as any sender or domain you add to your protected senders list.

Which browsers does Clean Mail Hub work in?

Clean Mail Hub works in Google Chrome and other Chromium-based browsers that support Chrome Web Store extensions, such as Microsoft Edge and Brave.

Can I use Clean Mail Hub with more than one Gmail account?

Yes. You can connect several Gmail accounts and switch between them from the account menu. Each account has its own cleanup history.

How do auto-clean rules work?

A rule combines conditions (sender, category, age, size, unread or attachment) with an action (move to Trash, archive, mark as read or apply a label) and a schedule (daily or weekly). Clean Mail Hub runs due rules automatically while your browser is open, and you can preview how many emails a rule matches before saving it.

How do I remove Clean Mail Hub and its access?

Log out from the extension’s account menu, which revokes its access token, then remove the extension from your browser’s extensions page. Uninstalling deletes all data the extension stored on your device.

Why Is Your Gmail Inbox Always Full?

Every online purchase, app and website adds you to another mailing list. Newsletters you never read, promotions, social notifications and old attachments pile up quietly, burying important email and eating into the free 15 GB of storage that Google shares between Gmail, Google Drive and Google Photos. Deleting them one by one takes hours, and they keep coming back. Clean Mail Hub fixes the cause as well as the clutter: it stops unwanted senders, clears what has already piled up, and keeps it from happening again.

Newsletters you never open

Find them by read rate and unsubscribe in one click.

Storage running out

Locate the biggest emails and attachments instantly.

Clutter that keeps returning

Rules clean new clutter automatically every day or week.

Everything You Need to Clean Up Gmail

Eight tools in one lightweight extension, built around one rule: you stay in control of your email.

One-click mass unsubscribe

Find every newsletter and mailing list from the last 12 months, see how many of their emails you actually open, and unsubscribe using each sender’s official unsubscribe link.

Auto-clean rules

Create rules such as “Promotions older than 30 days → Trash” or “Unread mail older than 90 days → Archive”. They run daily or weekly without you lifting a finger.

Bulk cleanup with preview

Filter by sender, domain, date range, age, category, unread status or attachment size. Preview the matching emails first, then clean them in one step.

Large email finder

List the emails using the most storage, from 2 MB to 20 MB and above, sorted by size, and free up space in seconds.

Inbox analysis

Real numbers from your mailbox: emails per category, unread rate, mail received in the last 30 days and your top senders with one-click actions.

Undo every cleanup

Nothing is permanently deleted. Cleaned emails go to Gmail Trash, and any cleanup can be restored from History with one click.

Protected senders

Add the people and domains that matter (your bank, your boss, your clients) and they will never be touched by rules or bulk cleanups.

Multiple Gmail accounts

Connect personal and work Gmail accounts and switch between them in one click. Each account keeps its own history and rules.

How to Clean Up Your Gmail Inbox in 4 Steps

From install to a clean inbox in a few minutes.

1
Install the extension
Add Clean Mail Hub to Chrome from the Chrome Web Store and pin it to your toolbar.

How to Mass Unsubscribe From Emails in Gmail

Unsubscribing is the only lasting fix for a cluttered inbox: deleting newsletters removes today's copies, but unsubscribing stops tomorrow's. Clean Mail Hub uses the official unsubscribe method that each sender includes in their emails (the List-Unsubscribe standard), so requests are handled the same way as Gmail's own unsubscribe link.

Open Clean Mail Hub and select the Unsubscribe tab.
Click Scan Subscriptions. Every mailing list from the last 12 months is listed with its email count and your read rate.
Sort by Least read to find the senders you never open.
Tick the senders you want to stop and click Unsubscribe.
Keep Also move their emails to Trash ticked to clear their old emails at the same time.

How to Free Up Gmail Storage Space

A handful of emails with large attachments often use more storage than thousands of text-only emails. Clearing them first gives you the biggest storage win for the least effort.

Open the Large tab and choose a size, such as larger than 10 MB, and optionally an age.
Click Find. Emails are sorted from largest to smallest with their size.
Select the ones you no longer need. The total space you will free is shown as you select.
Click Move to Trash, then empty Gmail Trash to release the space immediately.

Tip: download important attachments to your computer or Google Drive before removing the emails.

Keep Gmail Clean Automatically With Auto-Clean Rules

Gmail filters only act on new messages as they arrive. Clean Mail Hub rules also clean up the mail that is already in your inbox, on a daily or weekly schedule. Starred and important emails are always skipped. Popular rules:

Condition	Action	Schedule
Promotions older than 30 days	Move to Trash	Daily
Social updates older than 14 days	Move to Trash	Weekly
Unread mail older than 90 days	Archive	Weekly
From receipts@yourshop.com	Apply label “Receipts”	Daily
Larger than 10 MB and older than 1 year	Move to Trash	Weekly
