If you would like to send out emails using an e-mail address with your personal domain name, make sure that the provider will provide you with access to their SMTP server. The latter is the software system that enables e-mail messages to be dispatched. SMTP is an abbreviation for Simple Mail Transfer Protocol and it addresses all outbound e-mails from applications, webmail and contact web forms. When a message is sent out, the SMTP server checks with all the DNS servers throughout the world where the emails for the receiving domain are handled and once it gets this information, it creates a connection into the remote POP/IMAP server to check if the recipient mailbox is out there. If it does, the SMTP server transmits the message body and so the receiving server delivers it to the mailbox where the recipient can open it and read it. Without an SMTP server on your server, you won't be allowed to send out messages in any way.
