I created two scripts on my script.google.com account that are helpful for managing email. Thanks to this post on the Official Gmail Blog by Corey Goldfeder. I was able to coble together two very useful functions. A delayed delete function that allows me to flag emails for deletion at a future date but still remain in my inbox for a fixed length of time. A snooze email feature that allows me to have flagged emails return to my inbox unread at a date in the future.
