⚠️ Warning: You may not be asked to confirm! If you want to revert this action, quickly click Undo in the message that appears at the bottom.

Keep in mind that it can take a significant amount of time for your emails to be removed, especially when deleting hundreds of thousands of messages.

Narrow Down the Deletion Selection in Gmail

If you want to delete all emails in your Inbox or for a label, the above steps work just fine. But maybe you want to remove certain messages, like those before a particular date or older than a specific timeframe. In this case, you can use Gmail’s search options or search operators to narrow down the results.

Search options: Click the Show search options button on the right side of the search bar, enter the criteria, and select Search.

Search operators: Enter one or more of the Gmail search operators in the Search box and press Enter or Return. As examples, to find emails before a certain date, use before:YYYY/MM/DD or to locate messages older than, say, one year, use older_than:1y.

After you filter your results, follow the above steps to delete the messages.

Delete Mass Amounts of Email in the Gmail Mobile App

While it’s a simpler, and oftentimes, quicker process to delete thousands of emails in Gmail on the web, you do have a way to remove messages in bulk using the mobile app.

  1. Open the Gmail app and go to your Inbox, All Mail, a label, or other location.
  2. Long-press (tap and hold) the first message you want to delete.
  3. Mark the Select all checkbox on the top left to select all 50 emails in view.
  4. Scroll to the bottom of the screen to load more messages.
  5. Mark the Select all checkbox again to choose the additional messages.
  6. Continue this process until you’ve selected all emails you want to delete.
  7. Tap Delete in the top toolbar.

Limitations With Gmail Bulk Delete

When you’re looking to delete 100,000 emails in Gmail or even three times that, there are some limitations to be aware of before you begin.

50-email per page limit: You can only see and select 50 emails at a time by default. You can look for the message at the top to select all emails and speed up the process on the web, but there isn’t currently an effective workaround in the mobile app.

Delete means Trash: Emails you Delete aren’t permanently removed. Instead, they go to the Trash where they remain for 30 days before they’re automatically and permanently deleted. This is important to keep in mind as emails in the Trash still contribute to your storage space. For more, check out Delete Vs. Trash: What’s the Difference?.

Slowdowns with large selections: You may experience a slowdown in Gmail, like this Reddit user, when you try to delete many, many emails at once. This can occur because of data propagation and server load. Additionally, a Gmail community member mentions that Google may consider this a compromised account — they suggest restricting the number of emails you delete at once and spacing out the process over hours.

To bypass these Gmail limitations, you can look at other tools like IFTTT. Unfortunately, these can be either too technical or unreliable at a large scale. And automations like Google’s Gemini AI are not useful for inbox cleanup.

Instead, consider Clean Email which is a safe, intuitive, and efficient mailbox management tool.
