CNAME Record

Creating a CNAME record for any of the domain addresses or subdomains you have in a hosting account allows you to redirect it to a different domain/subdomain. The forwarded domain name will lose all of its records - A, MX and so on, and will take the records of the Internet domain it's being forwarded to. In this light, you simply can't set up a CNAME record to redirect your domain to a third-party provider and maintain a working email service with the first hosting company. It is also important to note that a CNAME record is always a string of words rather than a number because it is often wrongly identified as the A record of the domain address being forwarded. One of the main uses of a CNAME record is to direct a domain address which you own through one provider to the servers of another provider if you have set up a website with the latter. This way, the site will appear under your own domain name, not under some subdomain provided by the third-party company.
