How to clean a Gmail inbox safely

1. Connect your Gmail account

Select Connect your mailbox on CleanMyBox and choose Continue with Google. Google handles authentication directly on its own sign-in page. After you sign in, review the requested permissions and approve the connection so CleanMyBox can scan and manage the messages required for the cleanup.

• Open CleanMyBox and select Connect your mailbox.
• Choose Continue with Google and select the Gmail account you want to clean.
• Review the requested access before approving the connection.
• Return to CleanMyBox and choose the Clean or CleanPlus plan.

2. A Google warning may be normal

Depending on the account and the current verification status of the application, Google may display an unverified-app warning during the connection flow. This is a Google OAuth notice, not a Gmail error or a problem with your mailbox. Review the requested access carefully and continue only if you recognize and trust CleanMyBox. Never enter your Google password on CleanMyBox: authentication should take place on Google’s own page.

• The warning can appear while Google’s application verification review is incomplete.
• Check the permissions shown by Google before continuing.
• Google Workspace administrators may restrict access to unverified applications.
• You can review or remove CleanMyBox from your Google Account’s third-party connections.

3. How the Gmail cleanup works

The standard Clean plan identifies newsletters and recurring promotional email using signals such as List-Unsubscribe and List-Id. It attempts official unsubscribe methods when available, marks matching messages as read, and moves cleanup targets to the trash while keeping uncertain messages.

• Detect newsletters and recurring promotional senders.
• Attempt official unsubscribe flows when available.
• Move relevant cleanup targets to the trash.
• Keep uncertain messages instead of applying a risky blanket rule.

4. What CleanPlus AI adds

CleanPlus adds AI-assisted classification to the mailbox scan. It can help distinguish useless newsletters, legitimate older messages, spam, phishing, and other potentially malicious or fraudulent email, then select a conservative action such as delete, archive, move to spam, or keep. Messages that remain uncertain are kept rather than guessed at.

• Classify promotional and newsletter clutter as useless when appropriate.
• Help identify spam, phishing, and potentially malicious messages.
• Archive useful but older messages when the classification supports it.
• Keep messages when the model is uncertain or the content may be important.

5. Review the result

When the run is complete, CleanMyBox provides a report showing scanned messages, detected newsletters, unsubscribe attempts, spam actions, deleted messages, archived messages, and items kept. This makes the result auditable instead of hiding the cleanup behind a single button.
