Spam Trash Auto Delete Gmail is a web app that uses the Gmail API to automatically and permanently delete spam and trash emails from your Gmail folders. With this app, you can set the interval for deleting spam and trash emails to any frequency you prefer, from every minute to every day. This app can be a useful tool to help keep your Gmail account clean and organized.

However, it is important to note that the app permanently deletes the emails, and you may accidentally delete important emails that shouldn't be in the spam or trash folders. Therefore, it is essential to use this app with caution to avoid deleting essential emails.
