Here’s how you can get auto-purge to work inside your Gmail:
- Open Google Script and choose File -> Make a copy to copy it into your Google Drive.
- Set the value of GMAIL_LABEL to the label that you wish to auto-purge and PURGE_AFTER are the number of days for which you to retain a message in Gmail.
- Go to Run -> Initialize and grant the necessary permissions. This is your personal script and nobody else will ever have access to your data.

That’s it. Exit the Google Script and it will continuously monitor that particular Gmail label in the background. If you need to disable auto-purging later, just open the same script in your Google Drive and choose Run -> Uninstall.
