When you've got an email and you enable forwarding for it, all of the incoming e-mails will be sent to a third-party email address that you choose. The sender won't be aware of this and he will send the message only to the original address. This kind of feature is useful in case you have a number of web sites, each with a different e-mail for contact, for instance. By forwarding all e-mails to a single email address, it will be simpler for you to monitor and not overlook an e-mail message because you have neglected to check on a certain e-mail. If you have a company, you’ll be able to take advantage of this feature to check the e-mails received by different divisions. An additional benefit is the fact that you're able to use an official e-mail address for some reasons, let’s say firstname.lastname@example.org, and you can now get all of the emails sent to it in your personal email address. In addition, you can forward emails from a single e-mail address to numerous ones, in case a number of individuals needs to be involved in the e-mail communication.
