When you've got an e-mail and you enable forwarding for it, all of the inbound e-mails will be sent to a third-party email address that you choose. The sender will not be aware of this and he will be sending the message to the original address. This kind of feature is effective for people with several websites, each with a unique email address for contact, for instance. By forwarding all messages to a single email address, it will be simpler for you to keep track and never neglect a message as you have overlooked to check a specific e-mail. If you have an enterprise, you can employ this feature to watch the emails received by various departments. An additional benefit is that you'll be able to work with an official e-mail address for some needs, let’s say firstname.lastname@example.org, and you can get all of the messages sent to it in your private mailbox. In addition, you can forward emails from a single email address to multiple ones, in case a number of people needs to be involved with the e-mail communication.
