电子邮件别名是一个额外地址，可将收到的邮件路由到现有邮箱，无需创建单独账户。例如，[email protected]和[email protected]都可以是投递到单一[email protected]邮箱的别名。与[[catch-all-email|全收地址]]不同，别名是明确定义的，不接受任意地址。别名与[[email-forwarding|邮件转发]]的区别在于，别名是[[email-hosting|邮件主机]]的原生功能，通常允许收件人从别名地址回复而不暴露底层邮箱。
示例
A founder sets up billing@, support@, and press@ as aliases all pointing to their primary inbox, then replies from the correct alias address to maintain professional separation without managing multiple accounts.
