The Gmail team provided a guide to help users remove their Gmail addresses from unwanted websites. Here’s a summarized explanation:

1. Identify the websites: Make a list of websites where your Gmail address is being used or shared.
2. Contact website support: Reach out to the customer support or help section of each website, requesting the removal of your Gmail address. This often involves sending an email or filling out a form.
3. Check privacy settings: Some websites have privacy settings that allow you to remove or hide your email address. Log in and navigate to your account settings to make necessary changes.
4. Use Google’s removal tools: For sites that appear in Google search results, you can use Google’s URL removal tool to request the removal of outdated or irrelevant information.
5. Unsubscribe from emails: Use the unsubscribe link often found at the bottom of unwanted emails to stop receiving communications from those websites.
6. Update your email address: If possible, update your email address on those websites to a secondary or disposable email to prevent further unwanted emails.
7. Report spam: Use Gmail’s spam reporting feature to flag unwanted emails, which helps improve Gmail’s spam filters.

Following these steps should help you minimize the unwanted use of your Gmail address on various websites.
