If you are using a Windows PC and you intend to use Outlook® for your email, you can enable Outlook Easy Setup. This will create an "autodiscover" entry under your SRV (Service) record, including all the information Outlook needs to allow you to set up your email account.
This feature will only work if your domain is registered in the same GoWebsite account, and uses GoWebsite nameservers. If your domain does not meet both those requirements, you can still set up an autodiscover entry, but please see Outlook (Windows): Manually add autodiscover SRV record.
Now, when you set up your email in Outlook, all you need to do is enter your username and password, and the SRV record does the rest.
