The fastest way depends on which email service you use
Gmail, Outlook, Yahoo Mail, and Apple Mail all let you delete large batches of email, but the steps are different for each one. The method also depends on whether you want to delete everything or just messages matching certain words, dates, or senders. Most services show you a preview of what will be deleted before the action is final, so you have a chance to stop if something looks wrong.
Deleting email in bulk is useful when you are cleaning up after a breach, removing spam that got past your filters, or just starting fresh. The process takes a few minutes and does not require any special software or passwords beyond what you already use to log in.
Key Takeaways
- Gmail lets you select all messages at once by clicking the checkbox at the top of your inbox, then delete them in one action — but this only works on the current page, so you may need to repeat the step for older messages.
- Outlook and Yahoo Mail have search filters that let you narrow down which messages to delete before you select them all, which is safer than deleting everything blindly.
- Apple Mail on Mac and iPhone requires you to select messages manually or use the search function to filter first, then delete the results.
- Deleted messages usually go to a Trash or Deleted Items folder first, where they stay for 30 days before being permanently removed — you can recover them during that window if you change your mind.
- If you are deleting email because of a security breach or scam, also change your password and check your account recovery settings after you finish.
How to delete all emails in Gmail
Open Gmail and go to your inbox. At the top left, you will see a checkbox next to the search bar. Click it. A menu will appear asking if you want to select all messages in your inbox — click "All" to confirm. Gmail will now highlight every message on the current page (usually 50 at a time). At the top, a bar will appear saying how many messages are selected. Click the trash icon or the three-dot menu and choose "Delete".
If you have thousands of emails, Gmail will only select the ones visible on your current page. After you delete them, go back to your inbox and repeat the process. Each time you delete a batch, the next oldest batch moves to the top. Keep doing this until your inbox is empty. This takes longer than deleting everything at once, but it is the only way Gmail lets you do a complete purge.
Messages you delete go to the Trash folder, where they stay for 30 days. After 30 days, Gmail permanently removes them. If you change your mind within those 30 days, open Trash, select the messages you want to keep, and click "Move to" to put them back in your inbox or another folder.
How to delete all emails in Outlook (web version)
Log into Outlook.com and open your inbox. Click the checkbox at the top left to select all messages on the current page. A message will appear asking if you want to select all messages in your inbox — click "Select all [number] items in Inbox". Now every message in your inbox is selected. Click the trash icon at the top to delete them all at once.
If you want to delete only certain messages — for example, only emails from a specific sender or older than a certain date — use the search box first. Type the sender's name or use filters like "before:2023-01-01" to narrow down which messages appear. Then select all the filtered results and delete them. This is safer than deleting everything, because you can see exactly what you are removing before you confirm.
Deleted messages go to your Deleted Items folder. They stay there for 30 days, then Outlook removes them permanently. To recover a deleted message, open Deleted Items, find it, right-click it, and choose "Move" to put it back in your inbox.
How to delete all emails in Yahoo Mail
Log into Yahoo Mail and open your inbox. Click the checkbox at the top left to select all messages on the current page. Yahoo will show you a message asking if you want to select all messages — click "Select all conversations in Inbox". Now every message is selected. Click the trash icon or the three-dot menu and choose "Delete".
Yahoo Mail also lets you use the search box to filter messages before you delete them. You can search by sender name, subject line, or date range. For example, searching "from:noreply@" will show you automated messages you might want to remove. Once you have filtered the results, select all of them and delete in one action.
Deleted messages go to your Trash folder for 7 days, then Yahoo removes them permanently. This is shorter than Gmail or Outlook, so if you think you might need a message back, recover it within a week. Open Trash, find the message, and click "Move to Inbox".
How to delete all emails on Apple Mail (Mac and iPhone)
On Mac, open Apple Mail and click on the inbox or folder you want to clear. Use the keyboard shortcut Command+A to select all messages in that folder. A menu may appear asking you to confirm — click "Select All". Now click the trash icon in the toolbar, or press Command+Delete. Messages move to the Trash mailbox.
On iPhone or iPad, open the Mail app and swipe left on a message to see the trash icon. Unfortunately, Apple Mail does not have a "select all" button on mobile, so you have to delete messages one at a time or a few at a time by swiping. If you have a large number of emails to delete on your phone, it is faster to do it on a Mac or computer instead.
On both Mac and iPhone, deleted messages stay in the Trash mailbox for 30 days before being permanently removed. To recover a message, open Trash, tap and hold it (or right-click on Mac), and choose "Move to Inbox".
What to do if you cannot delete messages
Some email accounts have restrictions that prevent bulk deletion. If you see an error message when you try to delete, check whether your account is a work or school email. Many organizations use email management software that locks down deletion to prevent accidental data loss. Contact your IT department or email administrator to ask if they can remove the restriction or delete messages on your behalf.
If you are using an older browser or an outdated version of your email app, the delete function may not work properly. Try opening your email in a different browser, or update your Mail app to the latest version. If the problem persists, try deleting a small batch of messages first to see if the issue is with the bulk action or with individual messages.
Protecting yourself after a breach or scam
If you are deleting email because you received a phishing message, fell for a scam, or learned your account was breached, deletion alone is not enough. After you finish deleting, change your email password to something new that you have not used anywhere else. Use a mix of uppercase and lowercase letters, numbers, and symbols — at least 16 characters is better than 12.
Next, check your account recovery settings. Go to your email provider's security page (Gmail Security, Outlook Security, Yahoo Account Security, or Apple ID Settings). Look for the phone number and backup email address linked to your account. If you do not recognize them, remove them. Add a phone number or backup email that only you control. This makes it much harder for someone else to take over your account if they somehow get your password.
If the scam involved money or sensitive information, also check your bank and credit card accounts for unauthorized charges. Consider placing a fraud alert with the three major credit bureaus (Equifax, Experian, and TransUnion) so lenders know to verify your identity before opening new accounts in your name.
Frequently Asked Questions
Will deleting emails free up storage space on my account?
Yes. Most email providers give you a set amount of storage — Gmail offers 15 GB free, Outlook offers 5 GB, and Yahoo offers 15 GB. Deleting messages frees up that space. However, messages in your Trash folder still count toward your storage limit until they are permanently deleted after 30 days, so do not expect your storage to drop when ready.
Can I undo a deletion if I deleted the wrong messages?
Yes, as long as you act within the recovery window. Gmail and Outlook keep deleted messages for 30 days; Yahoo keeps them for 7 days. Open your Trash or Deleted Items folder, find the messages you want to keep, and move them back to your inbox. After the recovery window closes, the messages are gone permanently and cannot be recovered.
What if I want to keep some emails but delete most of them?
Use the search or filter function in your email provider before you delete. Search for a sender name, subject line, date range, or keyword to show only the messages you want to remove. Then select all the filtered results and delete them. This is much safer than deleting everything and trying to recover what you wanted to keep.
Do I need to delete emails from my phone and computer separately?
No. Most email providers sync deletions across all devices. If you delete an email on your computer, it will also disappear from your phone within a few minutes. The exception is Apple Mail on Mac and iPhone — if you use Apple Mail on both devices, deletions sync automatically, but if you use a different app on one device, you may need to delete separately.
What happens to emails I have forwarded to someone else?
Deleting an email from your account does not delete it from the recipient's inbox. They still have a copy. If you need to remove a message from someone else's account — for example, because it contains sensitive information — you have to contact them directly and ask them to delete it themselves. Most email providers do not let you delete messages from other people's inboxes.
