The fastest way depends on your email service
Most email services let you select and delete large batches of messages from the inbox view, but the exact steps vary. Gmail, Outlook, Yahoo Mail, and Apple Mail all have a "select all" option that works within your current folder or search results — but they handle it differently, and some have limits on how many messages you can delete in one action.
If you want to clear everything, the safest approach is to search for all messages first, then delete what the search returns. This gives you control over what goes and prevents accidental loss of messages you meant to keep. Some services also offer a nuclear option: deleting your entire account, which removes all email permanently.
Key Takeaways
- Gmail, Outlook, and Yahoo Mail let you select all visible messages and delete them in batches, but the process differs slightly for each service.
- Searching for all mail first (using a broad search term) before deleting gives you a chance to review what you are about to remove.
- Most services delete messages to a Trash or Deleted Items folder first, giving you a window to recover them before permanent removal.
- Permanently emptying your Trash folder is a separate step from deleting individual messages and cannot be undone.
- If you want to delete email from a specific sender or date range, using search filters before selecting all is faster and safer than manual deletion.
How to delete all email in Gmail
Open Gmail and go to your inbox. In the search box at the top, type in:anywhere to pull up every message in your account across all folders. This search returns all mail except messages in Trash and Spam.
Once the search results load, look for the checkbox at the top left of the message list (above the first email). Click it to select all messages shown on the current page. Gmail will then show a prompt asking if you want to select all matching messages — click the link that says "Select all [number] conversations." This selects everything the search returned, not just what is visible on screen.
With all messages selected, click the delete button (trash icon) in the toolbar. Gmail moves the messages to Trash. To permanently remove them, go to the Trash folder, select all messages there the same way, and click delete again. Messages in Trash stay for 30 days before Gmail removes them automatically.
How to delete all email in Outlook
Open Outlook and click on your inbox. At the top of the message list, you will see a checkbox next to "Select." Click it to select all messages currently visible. Outlook will show a link saying "Select all [number] items in this folder" — click that link to select everything in the inbox, not just what is on screen.
Once selected, click the delete button in the toolbar (usually a trash icon). Outlook moves messages to the Deleted Items folder. To clear them permanently, open Deleted Items, select all messages the same way, and delete again. You can also right-click the Deleted Items folder and choose "Empty Folder" to remove everything at once without selecting manually.
If you want to delete mail from multiple folders, repeat this process for each folder. Outlook does not have a built-in "select all mail everywhere" option the way Gmail does, so you will need to go through Inbox, Sent Items, and other folders separately.
How to delete all email in Yahoo Mail
Log into Yahoo Mail and open your inbox. Click the checkbox at the top left of the message list to select all messages on the current page. Yahoo will show a prompt asking if you want to select all messages in the folder — click "Select all" to confirm.
With all messages selected, click the delete button (trash icon) in the toolbar. Messages go to the Trash folder. To permanently remove them, open Trash, select all messages, and delete again. Yahoo keeps messages in Trash for 7 days before removing them automatically.
Yahoo Mail does not have a search-all feature like Gmail, so if you want to delete everything across all folders, you will need to go through Inbox, Sent, Drafts, and other folders one at a time using the same select-all process.
How to delete all email in Apple Mail
Open Apple Mail and click on your inbox in the sidebar. Use the keyboard shortcut Command + A to select all messages in the current folder. Alternatively, click the first message, then hold Shift and click the last message to select everything in between.
Once selected, press the Delete key or click the delete button in the toolbar. Apple Mail moves messages to the Trash mailbox. To permanently remove them, click Trash in the sidebar, select all messages the same way, and delete again. You can also right-click the Trash mailbox and choose "Erase Deleted Items" to remove everything without selecting manually.
Apple Mail works on a folder-by-folder basis, so you will need to repeat this process for Inbox, Sent, Drafts, and other folders if you want to clear everything. Unlike web-based email services, Apple Mail does not have a search-all feature built into the delete workflow.
Using search to delete specific batches of email
If you do not want to delete everything, you can use search to target specific messages before deleting. This is useful if you want to remove old mail from a certain date, messages from a specific sender, or emails with particular words in the subject line.
In Gmail, search for before:2020 to find all messages sent before January 1, 2020, then select all and delete. In Outlook, use the search box and filter by sender, date, or subject, then select all results and delete. Yahoo Mail and Apple Mail have similar search filters in their search boxes.
After you delete messages using search, they go to Trash or Deleted Items just like regular deletions. You still need to empty that folder separately to remove them permanently. This two-step process — delete to trash, then empty trash — gives you a chance to recover messages if you change your mind.
What happens after you delete: recovery and permanent removal
When you delete a message, it does not disappear immediately. Gmail keeps deleted messages in Trash for 30 days. Outlook keeps them in Deleted Items indefinitely unless you empty the folder. Yahoo Mail keeps them in Trash for 7 days. Apple Mail keeps them in Trash until you manually empty it.
During this window, you can recover deleted messages by opening the Trash or Deleted Items folder, selecting the messages you want back, and moving them to your inbox. After the time period expires or you empty the trash folder, the messages are gone and cannot be recovered through the email service.
If you delete your entire email account through your service provider's account settings, all messages are removed permanently and the recovery window does not apply. This is a separate action from deleting individual messages or folders.
Frequently Asked Questions
Can I delete all email without losing important messages?
Yes. Before deleting, search for messages you want to keep (like emails from your bank or doctor) and move them to a separate folder. Then delete everything else. You can also export important messages to a file before deleting, which creates a backup you can refer to later.
What if I accidentally delete something I need?
Go to your Trash or Deleted Items folder immediately and move the message back to your inbox. Gmail gives you 30 days to recover deleted mail, Outlook keeps it indefinitely, and Yahoo Mail keeps it for 7 days. After that window closes or you empty the trash folder, recovery is not possible.
Does deleting email free up storage space?
Yes, but only after you empty your Trash or Deleted Items folder. Deleting a message to trash does not free space — you have to remove it from trash permanently. Once you do, the space becomes available in your email account.
Can I schedule email deletion instead of doing it all at once?
Gmail, Outlook, and Yahoo Mail do not have built-in scheduling for bulk deletion. You have to delete messages manually. Some third-party tools claim to automate this, but they require you to give them access to your email account, which carries security risks.
What is the difference between deleting and archiving?
Deleting removes messages from your inbox and sends them to trash. Archiving moves messages out of your inbox but keeps them in your account and searchable. Archived messages do not take up inbox space but still count toward your storage limit. If you want to keep messages but hide them, archiving is safer than deleting.
