The fastest way depends on your email provider and how much you want to keep
You can delete all email in most providers in under five minutes using the select all feature, but the exact steps differ between Gmail, Outlook, Yahoo, and others. If you want to keep some messages — like receipts or important confirmations — you should sort or filter first, then delete only what you want gone. Deleting everything at once is permanent after 30 days in most services, so take a moment to decide what stays.
The safest approach is to read a backup of your email before you delete anything, especially if you have years of messages. This takes longer but means you can recover something if you change your mind later.
Key Takeaways
- Gmail, Outlook, and Yahoo all let you select all messages at once, but the button location and process differ slightly between them.
- Messages go to trash or a deleted folder first and stay there for 30 days before permanent removal, giving you time to recover them.
- Filtering by sender, date, or subject before you delete lets you keep important messages while removing the rest in one action.
- Downloading your email as a backup file before deletion protects you if you need to recover something later.
- Deleting all email does not close your account — your inbox will be empty but your email address still works.
How to delete everything in Gmail
Open Gmail and go to your inbox. Click the checkbox at the top left, above your message list — this is next to the arrow icon. A menu will appear asking if you want to select all conversations. Click Select all conversations that match this search. Gmail will highlight all your messages, even ones you have not scrolled to yet.
Once everything is selected, a trash icon will appear at the top of your message list. Click it. Gmail will move all messages to your Trash folder. They stay there for 30 days. If you want them gone when ready, open Trash, select all again, and click delete permanently. If you change your mind within 30 days, go to Trash, select what you want back, and click the move icon to return messages to your inbox.
If you want to keep some messages, use the search box instead. Type a sender's name, a date range, or a word from the subject line. Gmail will show only matching messages. Select all of those, delete them, and leave the rest untouched.
How to delete everything in Outlook or Outlook.com
Open Outlook and click your inbox. At the top of your message list, you will see a checkbox. Click it to select all messages on the current page. A banner will appear asking if you want to select all messages in your inbox — click that option. Outlook will select every message, including ones you have not scrolled to.
Once selected, click the trash or delete icon at the top. Outlook moves messages to your Deleted Items folder. They stay there for 30 days before Outlook removes them permanently. To recover messages within that window, open Deleted Items, select what you want, and click Restore.
Outlook also lets you filter before deleting. Use the filter icon to show only messages from a specific sender, date range, or with certain words. Select all filtered results and delete only those, leaving everything else in place.
How to delete everything in Yahoo Mail
Open Yahoo Mail and click your inbox. At the top left, click the checkbox next to the search bar. This selects all messages on your current page. Look for a link or button that says Select all or Select all messages — click it to select your entire inbox at once.
Once all messages are selected, click the trash or delete button. Yahoo moves them to your Trash folder, where they stay for seven days before permanent removal. If you need to recover messages, open Trash within seven days, select them, and click Restore or Move to Inbox.
Yahoo's search and filter tools work the same way as Gmail and Outlook. Search for a sender, date, or subject, select all results, and delete only those messages while keeping the rest.
Backing up your email before you delete
If you have years of email and want a safety net, read your messages before deleting. Gmail lets you export your data through Google Takeout. Go to takeout.google.com, sign in, and select Mail. Google will create a file with all your messages and let you read it. This file is large if you have thousands of emails, so it may take a few hours to prepare.
Outlook users can export mail through their account settings. Go to Settings, click Mail, then Backup, and follow the prompts. Outlook will read your messages as a .pst file that you can open in Outlook later if you need to search for something.
Yahoo does not have a built-in export tool, but you can use third-party software like Thunderbird or MailStore to read your Yahoo messages. These programs connect to your Yahoo account and save all your email to your computer. The process takes longer than Gmail or Outlook but gives you a complete backup.
What happens to your account after you delete everything
Deleting all your email does not close your account or change your email address. Your inbox will be empty, but you can still send and receive messages. Your account settings, contacts, and calendar (if you use one) stay exactly as they were. You can start fresh with a clean inbox while keeping everything else.
If you have filters or rules set up — like automatically sorting mail from certain senders into folders — those stay active even after you delete all messages. If you want to remove those too, go to your settings and delete the rules you no longer need.
Deleting email in batches if you want to keep some
If you want to delete most of your email but keep certain messages, sort before you delete. In Gmail, use the search box to find messages by date: search before:2020/01/01 to show everything before January 1, 2020. Select all results and delete them, leaving newer messages untouched.
In Outlook, use the filter menu to show messages from a specific date range or sender. Select all filtered results and delete them. Yahoo has similar filtering options in its search menu.
Another approach is to move important messages to a separate folder first. Create a folder called "Keep" or "Archive", drag your important messages there, then delete everything in your inbox. This way you have a backup of what matters and a clean inbox at the same time.
Frequently Asked Questions
Can I undo a delete if I accidentally deleted something I needed?
Yes, for 30 days in Gmail and Outlook, and seven days in Yahoo. Open your Trash or Deleted Items folder, find the message, and click Restore or Move to Inbox. After that window closes, the message is gone permanently unless you have a backup file.
Will deleting all my email affect my contacts or calendar?
No. Deleting email only removes messages from your inbox and folders. Your contacts list, calendar events, and account settings stay the same. You can delete all your email without losing any other information.
How long does it take to delete thousands of emails at once?
Selecting and deleting all messages takes a few minutes. Moving them to trash is when ready. Permanently removing them from trash takes longer — Gmail and Outlook may take several hours to process permanent deletion of very large inboxes, but you do not have to wait for it to finish.
What if I only want to delete emails from one sender?
Search for that sender's email address or name, select all results, and delete them. This removes only their messages while keeping everything else. You can do this for multiple senders one at a time, or use filters to delete messages matching specific words or dates.
Does deleting email free up storage space on my computer?
No. Email stored in Gmail, Outlook, or Yahoo lives on their servers, not on your computer, so deleting it frees up space in your email account but not on your device. If you downloaded email to your computer using a program like Thunderbird, deleting it from the server does not remove the local copy — you would need to delete that separately.
