If you have 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 pick. The e-mail sender will not be aware of this and he will be sending the message only to the initial address. This kind of function is useful for people with a number of web sites, each one with a unique email address for contact, for example. By forwarding all emails to one particular e-mail, it will be easier for you to monitor and never pass up an email as you have overlooked to check on a certain e-mail. In case you have an enterprise, you are able to take advantage of this function to check the emails received by different divisions. Another advantage is the fact that you're able to use an official address for various reasons, let’s say firstname.lastname@example.org, and you can now get all of the e-mails sent to it in your personal mailbox. In addition, you can forward emails from a single e-mail to multiple ones, if a number of people needs to be involved with the email conversation.
