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 are sent 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 contact@yourdomain.tld to fruitman69@gmail.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 and shields personal email addresses from the outside.
Need an alternative to forwarders? Set up your custom domain email in Gmail, or you can set up your email in Outlook.
