re4box

Your inbox, back under control.

re4box is the control layer for Gmail, Outlook, and Exchange — not another mail client. Connect the account you want to simplify. Then put repetitive mail on rules, clear subscriptions from one list, and run bulk actions that keep going after you close the app.

Mail stays with your provider. re4box sits next to Gmail, Outlook, and Exchange. You are not locked into a new inbox.

RULES
Create a rule from any email, sender, or domain in seconds. Matching mail can be moved to Trash, archived, moved to a folder, marked as spam, starred, marked as read, or permanently deleted.

Filter-capable actions sync as real mailbox filters, so new mail is handled as it arrives. Apply the same rule to mail already in the box. Mark a sender as Approved to keep them trusted in Discover without changing the action.

Open a message and start a rule for that sender’s future mail in one tap. In Rules, search, group by domain, and hide Approved or already-synced items.

DISCOVER
One scan groups senders by domain and shows who actually fills the mailbox. Hide senders that already have a rule. Swipe to approve, create a Trash rule, or move a sender into a folder you choose. Treat a domain and a nested sender separately, so one noisy list does not take down a whole company.

Keep using the app while the scan runs. You get a notification when it finishes. Mail bodies are not saved for the scan — only the headers needed to group senders and find unsubscribe links.

UNSUBSCRIBE
Discover lists subscriptions and how each one lets you leave: one-click inside the app, a web page, or a mail-based flow. Filter by method. Confirm once. No more opening ten newsletters to hunt for a single link.

BULK ACTIONS
For a one-time sweep, pick a group and an action. The job runs on the server in secure batches. Close the app. Get a notification. Stop anytime: the current batch may finish, later batches will not run, and completed steps are not undone.

• Spam / Junk — that folder only
• Old emails — choose a cutoff (30 days, 60 days, 90 days, 6 months, 1 year, or 2 years). Covers all received mail older than that cutoff. Spam, Trash, Drafts, and Sent excluded
• Unread — every folder, including Spam and Trash, so the scope is honest
• One-click unsubscribe — senders with one-click List-Unsubscribe (Gmail and Outlook; not Exchange)

Actions: move to Trash, archive, mark as read, or permanently delete. Permanent delete asks for a second confirmation and cannot be undone.

INBOX
Search. Open a message. Move, star, archive, mark as read, delete, or select many at once. Switch accounts from the header. Add another Gmail, Outlook, or on-premises Exchange mailbox when you are ready.

Gmail and Outlook sign in with OAuth — your password stays with Google or Microsoft. Exchange connects through your company’s EWS server with work credentials.

Notifications can tell you when a scan or bulk action finishes. New-mail notifications are available for Gmail and Outlook (not Exchange yet).

Light, dark, or follow the system. Seven languages: English, Türkçe, Español, Português, Deutsch, Français, and 日本語.

PRIVACY
re4box is built to manage mail, not to keep a copy of it. Server tokens are encrypted. The local cache on your phone is encrypted. Sessions use the device keystore / Keychain. Remove an account from this device and keep your rules, or permanently delete re4box data while leaving Gmail, Outlook, or Exchange itself untouched. We do not sell your inbox and do not use it to track you across other apps.

FREE AND PREMIUM
