Within your cPanel hosting service you are able to setup an email forward, either to another @domain.com email address or to another email provider such as gmail. For email you may forward emails from your sales@domain.com hosted email address to your personalemail@gmail.com address. To do this:

1. Login to cPanel.
2. Within the Email section, click the Forwarders icon.
3. Click Add Forwarder.
4. Enter the email address you need to forward in the "Address to Forward" field.
5. Enter the email address which those emails will be forwarded onto in the "Forward to email address" field.
6. Click Add Forwarder.

Provided your domain name is pointed at the server, this change will come into effect immediately.
