Use your endless Gmail addresses to tidy your inbox

Did you know that your gmail address can give you an almost infinite number of e-mail aliases, which in turn can be used to organise your e-mails for greater efficiency?

Add a plus (+) sign followed by any word (e.g. johndoe+work@gmail.com) and you'll still get emails at the inbox of your primary address (johndoe@gmail.com) - but they'll come filtered.

Here are five ways you can utilise this feature to tidy your inbox and boost your productivity.
