Domain Basics

In order to get the most from your Teachable courses, it's very useful to understand a few basics about domains and how they're managed on Teachable. This information is particularly helpful if you already have a registered domain name and want to know how to integrate your new Teachable account with it, or if you would like to create a custom domain name for your Teachable courses.

About Domains

A domain, or domain name, is part of the web address (or URL) that people type into their browser to find your website on the internet. The URL appears in the address bar of your web browser (for example, Chrome, Firefox, Internet Explorer, or Safari).

Anatomy of a Domain

The domain name can be broken up into three main parts: the root domain (, the subdomain (design-academy), and the subdirectory (courses).

Your Website’s Root Domain

The root domain of a website is the domain name you need to buy/register with a TLD (top-level domain) extension (like .com, .edu, .gov), followed by a forward slash. If you have a personal website, you have already bought/registered a domain name.

If you have a free Teachable account, the root domain for your Teachable course is If you upgrade to a Basic or Professional plan, you can create/add a custom domain name. You might want to do this if you already own a domain name and want to add your Teachable course to it.

Your Website’s Subdomains

The subdomain of a website is a “sub-web site” within the main website that does not require a uniquely registered domain name. When you create a free Teachable school account, you are given the option to customize your subdomain.


Your Website’s Subdirectories

A subdirectory is a file that is located on your website. The subdirectory is located in the URL after the subdomain and root domain.


On Teachable you can add pages to your school which will appear as subdirectories. These subdirectories can be used to inform your students about things like your privacy policy or terms of use. You can also add pages, like an About Us page or a blog, to create a better experience for your students or to replace pages on a personal site you may have been using before

Your Primary Domain

When you have more than one custom domain, you must set one as your primary domain or the default will be the initial domain created. The primary domain is the root domain and will appear as such for all of your school’s course pages.

About DNS Records

The Domain Name System is a regulated service using a hierarchical naming system for computers, or any resource connected to the World Wide Web. DNS records route requests to the appropriate websites so that people can access information on webpages.

A Records

A records are a type of DNS record that is used to direct a domain or subdomain to an IP address. To assign a value to an A record, you need to provide your DNS management panel with an IP address where the domain or subdomain should point.

CNAME Records

A CNAME record is a canonical record, which makes one domain an alias for another domain. It is used to associate new subdomains with existing domain DNS Records. If you want to use your existing website domain and have your Teachable course point to it, you need to create a CNAME record.

MX Records

MX records are records that help route email messages to the appropriate places on the internet. An MX record is used to tell the world which machines accept incoming mail for your domain and where emails sent to your domain should be routed to.
