Clean your mailbox — every folder, every account
A mailbox is more than an inbox — sent mail, archives, spam and trash all accumulate too, and on quota-limited accounts they all count. ClearInbox is a clean mailbox app that sweeps the whole structure: it helps you clean out mailbox clutter folder by folder, clear mailbox storage, and keep the entire account tidy from then on.
Clean up your mailbox folder by folder
Smart folders cut across your whole mailbox, not just the inbox: old mail wherever it lives, oversized attachments in Sent as much as Received, newsletters filed and forgotten years ago. Each slice gets a count and a bulk action, so you clean up mailbox debt systematically instead of by scrolling.
Clear mailbox storage, not just message counts
Storage follows the big attachments. The Large smart folder surfaces the few hundred messages holding most of your bytes; delete or archive them, empty Trash and Spam (both count against quota until emptied), and watch the usage bar actually move.
A mailbox cleanup tool that keeps working
After the first clean-out, Auto Clean rules maintain the result: age-out promotions, keep-newest for alerts, archive stale notifications — per folder, per sender, on a schedule, across Gmail, Outlook, Yahoo, iCloud and any IMAP account.
Frequently asked questions
How do I clean out my mailbox quickly?
Work by slice, not by scroll: bulk-handle old mail, large mail and dead subscriptions first — that is usually 80% of the volume. ClearInbox pre-builds those slices, so a full mailbox clean-out typically takes under an hour.
Does cleaning my mailbox free storage space?
Yes, once Trash and Spam are emptied — until then, deleted mail still counts against your quota. The Large folder is the fastest route to meaningful space.
Can one app clean mailboxes from different providers?
Yes — connect Gmail, Outlook, Microsoft 365, Yahoo, iCloud, AOL, Fastmail or any IMAP account and clean them all with the same tools in one dashboard.
