Creating an e-mail alias means making an e-mail address which shares the exact same mailbox with a totally different e-mail address both for the inbound as well as the outgoing email messages. For example, you are able to make an address [email protected] and it'll be linked to its very own mailbox. Then, you can create an alias [email protected], which will make use of the mailbox of [email protected] and does not have a mailbox of its own. When you check your e-mails, you will notice e-mails sent to both of the two addresses in one place, which can be more convenient in some circumstances since you will not have to sign in and out of different mailboxes working with webmail or create multiple addresses inside an email application. This option is frequently used as a replacement for forwarding e-mail messages from a single e-mail address to another one if numerous addresses are mentioned for contact on a website.
