I have been receiving the following email since Sept 1 . Prior to that I had set up Gmail Meter in Google Docs/Drive but deleted the spreadsheet. How can I stop receiving th
Here is a solution that helped me:
Go to script.google.com. Go to "Resource" -> "All your triggers".
A rename dialogue should pop up prompting you to save this fake script. Click Ok.
Try to find the trigger that's sending the email and delete it.
Now all your triggers should appear - even for documents that you've already deleted from Google Docs/Drive.
Good luck!
There is probably a trigger that is still in your trigger list, to remove it simply open any script in the script editor and go to /ressources/all your triggers/ and delete it.
