As an additional alternative, it should be possible to specify a label in the options for GmailApp.sendEmail().

A work-around is proposed in StackOverflow: http://stackoverflow.com/a/18727687/1677912

Are there any news on adding the ability to archive and add a label to specific emails (not threads)? From a corporate shared mailbox perspective auto threading emails by subject is a serious issue (eg. we recive two emails from the same person with same subject but with different description).

Since it's available in pure mailbox view is that such a big effort to make it available also in Google Script?

Looking forward to having this implemented. As has been mentioned automatic threading based on subject is a big no-no for our enterprise. We get automated reports and other documents sent to us by customers and suppliers and they are lumped together in threads making it very difficult for me to let Apps Script process them automatically since labels (i.e. outlook folders) have to be applied to entire threads (even though the messages in these threads often need to be treated differently).

Please add this function (and message.getlabel too) we need to scan message not only the thread.
