You can try the Send Email Service Module to achieve your requirement. though its a Subscription based module. you can only test upto 1000 emails. You will get a username and key. just copy it and paste it into your imported module
Alternatively, if you have your own email service, you can use the Email Connector to send and receive emails. It also allows you to trigger logic on incoming emails, in case you are planning to kick off workflows based on received emails.
