Create script to delete all messages with label

To automatically delete sent emails, create filter from ME@gmail.com and add label ToBeDeleted.
Then create new script on script.google.com

function deleteSentMails() {
var label = GmailApp.getUserLabelByName("ToBeDeleted");  
var threads = label.getThreads();  
for (var i = 0; i < threads.length; i++) {  
    threads[i].moveToTrash();
    } 
}

And add trigger to run it every day for example between 02:00 and 03:00.
