Running this function will also prompt you to authorize the script to use Gmail. 

This function makes use of the “getLabelName” helper function, which will be used by the code below.

The “moveSnoozes” function moves messages one day forward in the queue, so that messages snoozed for 6 days are now snoozed for 5 days, etc. 

Messages in the 1-day label are moved back into the inbox, 

and potentially marked as unread. 

To make this work automatically, you’ll need to create a nightly event trigger to run “moveSnoozes”. 

See the more detailed instructions at the bottom of the post.
