Forwarders are great, and cPanel comes with forwarders built-in. This is great because it simplifies the process of creating them, meaning anyone with a cPanel Hosting account or a cPanel licensed VPS can redirect multiple emails with a few clicks.
They utilize the well-known concept of email forwarding, meaning emails sent to an address send straight to another address. This is useful if you have an irrelevant email address that you want to associate with a specific business or website area. Also, if set up correctly, email forwarding can reduce your resource usage, giving you more freedom to grow.
For example, a forwarder set up from firstname.lastname@example.org to email@example.com from a customer perspective, the latter is very unprofessional and could turn people away from you and your business.
Forwarders can be a simple and effective solution for small businesses. For example, they can be used to centralize multiple different contact channels to one address. This makes it easier to control multiple contact areas without needing and shielding personal email addresses from the outside.
