cPanel offers email service that's hosted locally on your cPanel account itself. However, if you want to use another email service, we offer a simple tool to help you route your email elsewhere using your domain name's MX records, which control the server which receives email sent to your domain.
Using this tool, you'll add MX records from your email provider, let them propagate across the Internet, and then remove the existing MX records. During the propagation time, email could be delivered to either your cPanel shared hosting account or your email provider.
Before changing your mail destination (i.e. your domain name's MX records), we recommend setting up your email address on the new service and making sure you have the MX records you need to use.
To prevent possible issues with your email service, we recommend starting with Priority 10 instead of 0 for the MX records you add.
At this point, we recommend waiting up to 48 hours for the changes to your domain name's email settings to propagate across the Internet. However, if your email isn't currently working or you don't mind downtime, you can proceed.
While this change propagates, email sent to your domain name might still get delivered to the email address on your cPanel shared hosting account.
