It is very easy to create new emails accounts under your domain from within your cPanel. Once logged into your cPanel, click on Email Accounts within the EMAIL section. On this page, towards the right-hand side click on +CREATE and in the "Username" field enter whatever you would like to use for your new email address.
**Note that the domain is populated on the right, so you do not need to enter it, only the username you would like to use before the @ symbol.
In the Password field you will either choose a password, or cPanel will allow you to automatically generate a secure password to use. You will need this password both to login to webmail, or to configure a third party email client. Make sure to save your password somewhere safe in the meantime.
You can then allocate the amount of space you want to this email account, or set it as Unlimited. Keep in mind that email storage does count towards your total account storage. Once you click +CREATE, your new email account is ready for use. You can immediately log into webmail and send/receive emails.
Webmail
You have two options for managing how you choose to send and receive your email. You can log directly into the server, which is webmail, or you can use a third-party email client such as Outlook, Thunderbird, Mac Mail, etc.
To access webmail directly from within the cPanel, click on the Email Accounts icon in the Email section of the cPanel. Once there you will see all of the email accounts you have available. To login to your email account select the Check Email button as shown below.
Once selected you will see all of the webmail options and settings. The default webmail client is Roundcube, and this will be shown at the very top of the page, just select the Open button to proceed.
You can access webmail with either method below:
https://domain.com/webmail
Alternately, you could browse to:
http://domain.com:2096
**Note that in both cases "domain.com" will need to be replaced with your actual domain name. This will remain true for the email client examples provided below as well. You can also log into your cPanel and click the Webmail icon to access your email directly on the server.
Third-Party Email Client
There are different options to view your email accounts other than using Webmail from within cPanel. The most common option would be Outlook, Google Fetcher, Thunderbird, and the mail icon on your mobile device. These settings are universal and will work with all providers.
Settings for connecting to third party email clients can be found by going into the cPanel. This can be located in the EMAIL section, and accessed by clicking the Email Accounts icon.
Once loaded, this page will show all of your email accounts that you have created. To the far right of the email that you are trying to set up, click the CONNECT DEVICES button.
After this page loads, you will first see we have automatic configuration settings that will automatically configure the client settings of your choice with the correct protocols. If your client is not listed below, you should use the Mail Client Manual Settings that can be used to connect anything else. These settings will be specific to the email and the server that you must use.. There are two options to connect: SSL and Non-SSL settings, the SSL settings should typically be used by default and will have additional encryption for your emails.
Everything listed here is is designed to make your email experience as easy and painless possible. For your convenience, there is even a built-in option located on that page as well to directly send the instructions to an email of your choice!
