Email aliases are alternative email addresses that forward incoming emails to a specified recipient’s primary email address. They act as virtual email addresses that redirect messages to the desired destination. Email aliases are commonly used to create departmental email addresses (e.g., sales@example.com) that forward emails to multiple team members or temporary email addresses for specific purposes (e.g., marketing@example.com). With email hosting, you can easily set up and manage aliases to streamline email communication and organization.
