A Domain Registration Service refers to registering the ownership of the domain name. There is no web space or email attached to it.
When you are paying for a Domain Registration Service, you are paying for the registration itself only. Not for web space or email.
To make your domain show up a web page when it is visited on a web browser, you need to use a Web Site Hosting Service with your domain. And to use an email address on your domain like [email protected], you need an Email Hosting Service.
Typically a Web Hosting Service covers both of them and it is the recommended way to use Web Site and Email for your domain.
If you are looking for a reliable web hosting service, we welcome you to check our own hosting service at WebHosting.com.bd.
However as complimentary the registrar is also providing Domain Forwarding, Weebly 1 Page Site, 2 Email Accounts, Email Forwarding and Managed DNS free of charge. If your requirements are very basic or you just want to get a web presence without any additional cost, you can use those services.
When using a free service kindly treat them as a complimentary service, not a service you have paid for. As those services are provided by the registrar, we do not have any access to the servers. And for that, the support we are able to provide for them is very limited.
