First time Gmail users always find one feature missing in Gmail i.e. folders. It is not possible for a Gmail user to organize a bunch of emails in single folder. But, Gmail has a unique way of organizing emails i.e. by adding labels.
A message can be added to only one folder, but many labels can be added to a single message making it easier to identify.
Today, Gmail has added new features which will help us to add labels to message or send them to a specified label similar to folder.
Just select the message and click on ‘Labels’ button to add labels or Click on ‘Move to’ button to send a mail to specific label which acts like a folder.
