The fastest way to clear your inbox
Most email providers let you select all messages and delete them in one action, though the exact steps depend on which service you use. Gmail, Outlook, Yahoo, and Apple Mail all have a "select all" button that works across multiple pages of mail — you do not have to delete messages one at a time. The catch is that deleted mail usually goes to a Trash or Deleted Items folder first, where it sits for 30 days before the provider permanently removes it. If you change your mind, you can recover messages from that folder during that window.
Before you delete everything, think about what you actually want gone. Many people mean "clear out the clutter" rather than "erase every message forever." If you have important receipts, confirmations, or records buried in your inbox, deleting all mail is permanent after the recovery period ends. A safer approach is to archive old messages instead, which removes them from your inbox but keeps them searchable and recoverable.
Key Takeaways
- Gmail, Outlook, Yahoo, and Apple Mail all have a select-all button that deletes multiple pages of messages at once, not just what is visible on screen.
- Deleted messages go to Trash or Deleted Items for 30 days before permanent removal, giving you time to recover anything you deleted by mistake.
- Archiving messages removes them from your inbox but keeps them searchable, which is safer than deletion if you might need them later.
- Some email providers let you set up filters to automatically delete messages from specific senders or with certain words, so you do not have to delete manually each time.
How to delete all mail in Gmail
Open Gmail in your web browser and go to your inbox. At the top left, you will see a checkbox next to the search bar. Click it to select all messages currently visible on the page. A banner will appear asking if you want to select all conversations in your inbox — click "Select all [number] conversations" to include every message, not just the ones you can see.
Once all messages are selected, a trash icon will appear at the top of the page. Click it to move all mail to Trash. Your inbox is now empty. The messages sit in your Trash folder for 30 days. If you want to permanently delete them immediately instead of waiting, open Trash, select all again, and click the delete icon a second time. After that, recovery is not possible.
If you want to keep certain messages, use Gmail's search and filter tools instead of deleting everything. You can search by sender, date, or keywords, select only those results, and delete just that group. This way you preserve important mail while clearing out the rest.
How to delete all mail in Outlook (web and desktop)
In Outlook on the web, click your inbox and look for a checkbox at the top left of your message list. Click it to select all messages on the current page. A prompt will ask if you want to select all messages in your folder — click that option to include everything. Then click the trash or delete icon at the top to move all mail to Deleted Items.
In Outlook desktop (Windows or Mac), the process is similar. Open your inbox, press Ctrl+A (Windows) or Command+A (Mac) to select all messages, then press Delete or click the delete button. Messages move to Deleted Items, where they stay for 30 days before Outlook removes them permanently. To empty Deleted Items immediately, right-click the folder and choose "Empty Folder."
Outlook also lets you create rules to auto-delete mail from certain senders or with specific subjects. Go to Settings > Mail > Rules to set this up, so future mail matching those criteria deletes automatically without you having to act each time.
How to delete all mail in Yahoo Mail
Log into Yahoo Mail and open your inbox. At the top left, click the checkbox to select all messages visible on screen. Yahoo will show a message asking if you want to select all mail in your inbox — click that option to include messages across all pages. Then click the trash icon to delete everything at once.
Deleted messages go to your Trash folder, where Yahoo keeps them for 7 days before permanent removal. This is shorter than Gmail or Outlook, so if you delete something by mistake, recover it quickly. To permanently delete messages right away, open Trash, select all, and delete again.
How to delete all mail in Apple Mail
Open Apple Mail on your Mac and click your inbox. Press Command+A to select all messages in the folder. Then press Command+Delete or click the trash icon in the toolbar. Messages move to the Trash mailbox. Apple Mail keeps deleted messages in Trash for 30 days by default, though you can change this in Mail settings.
To permanently delete messages immediately, open the Trash mailbox, select all messages, and press Command+Delete again. You can also right-click Trash and choose "Erase Deleted Items" to remove everything at once without selecting first.
On iPhone or iPad, open Mail, tap Edit in the top left corner of your inbox, then tap Select All. Tap Trash or Delete (the wording varies by iOS version) to move all messages out of your inbox. The process is the same for other folders like Sent or Drafts.
Why archiving might be better than deleting
Deleting mail is permanent after the recovery period ends, but archiving keeps messages safe and searchable. In Gmail, archiving removes messages from your inbox but stores them in an "All Mail" folder where you can find them anytime using search. Outlook has a similar feature called Archive. Yahoo Mail calls it "Not in Inbox." Apple Mail does not have a built-in archive, but you can create a separate folder and move old messages there instead of deleting.
Archiving is useful if you want a clean inbox but might need receipts, confirmations, or records later. You can archive by date, sender, or subject, so you keep what matters and hide the rest. This approach also protects you if you delete something important by mistake — archived mail is still there, just out of sight.
Setting up automatic deletion with filters
Instead of manually deleting all mail at once, you can set up rules to automatically delete certain types of messages going forward. In Gmail, go to Settings > Filters and Blocked Addresses > Create a new filter. Enter the sender address or keywords you want to target, then choose "Delete it" as the action. Gmail will automatically delete matching messages from that point on.
Outlook has a similar feature called Rules. Go to Settings > Mail > Rules and create a rule that deletes messages from specific senders or with certain subject lines. Yahoo Mail offers Filters under Settings. Apple Mail on Mac uses Rules under Mail > Preferences > Rules. Setting these up takes a few minutes but saves you from having to delete the same types of messages repeatedly.
Be careful with automatic deletion rules — once a message is deleted by a rule, you cannot recover it. Test the rule on a small group first, or use automatic archiving instead if you are unsure.
Frequently Asked Questions
Can I recover mail after I empty the Trash folder?
No. Once you empty Trash or Deleted Items, the messages are gone permanently and cannot be recovered. Most providers give you 30 days (Yahoo gives 7) to change your mind while messages are still in Trash. After that window closes, recovery is not possible. If you delete something important, act quickly and check your Trash folder right away.
Will deleting all my mail affect my email account or settings?
No. Deleting messages does not change your password, contacts, calendar, or any other account settings. Your email address remains active and you can still send and receive new mail. Only the messages themselves are removed from your inbox and folders.
What is the difference between delete and archive?
Deleted messages go to Trash and are removed permanently after 30 days. Archived messages stay in a separate folder (like "All Mail" in Gmail) and remain searchable forever. Archive is safer if you might need old messages later, while delete is better if you want to clear space and do not plan to look back.
Can I delete mail from my phone the same way as on a computer?
Yes, but the steps are slightly different. On iPhone or iPad Mail, open your inbox, tap Edit, then tap Select All or select individual messages. Tap Trash or Delete to remove them. On Android Gmail, open your inbox, tap the three-line menu, select messages, and tap the trash icon. The process is faster on a computer, but phone deletion works the same way.
What if I only want to delete old mail, not everything?
Use your email provider's search tool to find messages by date. In Gmail, search for "before:2023-01-01" to find all mail from before that date, then select and delete just those results. Outlook and Yahoo have similar date search options. This way you keep recent mail and only clear out older messages.
