Delete all mail on gmail

To delete all emails on Gmail, you can follow these steps:

Method 1: Using the Gmail Web Interface

  1. Log in to your Gmail account on the web.
  2. Click on the gear icon in the upper right corner of the page.
  3. Select "See all settings" from the dropdown menu.
  4. Scroll down to the "Filters and Blocked Addresses" tab.
  5. Click on the "Create a new filter" button.
  6. In the "From" field, enter "me" (without quotes).
  7. Click on the "Create filter" button.
  8. In the "Apply the label" dropdown menu, select "Delete it".
  9. Click on the "Create" button.

This will delete all emails in your inbox, including any labels or filters you may have applied.

Method 2: Using the Gmail Mobile App

  1. Open the Gmail app on your mobile device.
  2. Tap on the three horizontal lines (menu icon) in the top left corner of the screen.
  3. Tap on "Settings" from the menu.
  4. Scroll down to the "General" section.
  5. Tap on "Delete all messages".
  6. Confirm that you want to delete all messages by tapping "OK".

Method 3: Using the Gmail API

If you have a large number of emails and want to delete them programmatically, you can use the Gmail API. You'll need to:

  1. Enable the Gmail API for your project in the Google Cloud Console.
  2. Create a service account and generate a private key file.
  3. Install the Google API Client Library for your programming language of choice.
  4. Use the library to authenticate with the Gmail API and delete all emails.

Here's an example of how you might do this in Python:

import os
import json
from google.oauth2.credentials import Credentials
from googleapiclient.discovery import build

# Set up authentication
creds = Credentials.from_service_account_file('path/to/service_account_key.json')
service = build('gmail', 'v1', credentials=creds)

# Delete all emails
response = service.users().messages().list(userId='me').execute()
messages = response.get('messages', [])

for message in messages:
    service.users().messages().delete(userId='me', id=message['id']).execute()

Note that deleting all emails on Gmail will permanently remove them from your account, so be sure to back up any important emails before doing so.
