Our domain email is only sold with web hosting. We do have email forwarding and the ability to set MX records for non-web hosting settings like domain parking and domain forwarding.
It appears that we are not the web host for octaltechnologies.com. Our domain email service is only sold as an add-on for our web hosting packages. Since you are using another company's web hosting package, you will need to ask them on how to set up your domain email.
