If you wish to send e-mails using an e-mail address with your domain name, make sure that the provider will provide you with usage of their SMTP server. The aforementioned is the software allowing e-mail messages to be transmitted. SMTP is an acronym for Simple Mail Transfer Protocol and it manages all outbound email messages from programs, webmail and contact forms. Every time a message is sent, the SMTP server checks with all the DNS servers globally where the e-mails for the receiving domain name are handled and as soon as it gets this data, it creates a connection into the remote POP/IMAP server to find out if the recipient mailbox is available. In case it does, the SMTP server transmits the email body and the receiving server sends it to the mailbox in which the recipient can open it up and read it. Without an SMTP server on your end, you will not be allowed to send messages in any way.
