Gmail Snooze is a Google Apps Script that adds the ability to "snooze" an email to classic Gmail. To snooze an email means to have an archived email reappear in the inbox after a set number of days. This is accomplished using special labels that the script sets up, and an Apps Script time trigger that moves emails between the labels around midnight in your local time.The original Gmail Snooze blog post can be found here: http://gmailblog.blogspot.com/2011/07/gmail-snooze-with-apps-script.html. This update works the same way, but is more user friendly to install and manage, as it no longer relies on a spreadsheet or changing code to configure it. In fact, the script has its own installer, and so if one user installs the code in their own account (using the "code installation" instructions below), any number of other users can install the functionality themselves without touching the code, simply by clicking an install link. This makes it easier to deploy in large organizations.
