Usually to access your Mailrelay account, you must use a URL similar to this: yourdomain.ipzmarketing.com Where “yourdomain” is replaced by the domain name of your company. Thus, this way the ending “.ip-zone.com” is always added to your domain name. But it is possible to make some settings for you to access directly using your domain name, for example: newsletters.yourdomain.com Or anything else you want in place of “newsletters”. If you want to make this change you will need to create a CNAME record in DNS for the subdomain you want. This must be done from the admin panel of your domain host, and must point to yourdomain.ipzmarketing.com Note that you must use a subdomain, pointing directly to the main domain could prevent your site to not work properly (if in doubt contact us before). For example, the following would NOT be correct: yourdomain.com CNAME yourdomain.ipzmarketing.com While the following would be fine: newsletters.yourdomain.com CNAME yourdomain.ipzmarketing.com Once these settings are done you only have to add the new subdomain in the Mailrelay panel, in the menu “Settings” -> “Custom Domain” NOTE: When you are about to create the CNAME record you must check that previously there was no subdomain with the same name. That is, if when you want to create a CNAME record named newsletters.yourdomain.com, if it already exists, you must choose another subdomain name, or delete the existing one.
