All of our hosting plans fully support sending/receiving email via POP3, SMTP, and IMAP. Webmail is also supported on all plans. The following details (specific to your domains) can also be found in cPanel under the "Email Accounts" interface, specifically by clicking "Connect Devices":

Incoming Server: mail.yourdomain.com
Outgoing Server: mail.yourdomain.com
Port: 25 or 26 (Some ISPs will block port 25. If you ever get an SMTP error, try using port 26)
SMTP Auth: Enabled/On

Your email addresses and passwords can be setup through the "Email Accounts" interface in cPanel. If you need help creating an email account, the article for that can be found here: https://support.hawkhost.com/index.php?/Knowledgebase/Article/View/38/0/how-do-i-create-email-accounts
