What is a subdomain?
A subdomain is a secondary domain that's part of a custom parent domain. For example, zyro.com is a custom domain, and example.zyrosite.com is a subdomain. All free Zyro domains are actually subdomains of zyrosite.com.
Where do I create subdomains if my domain (that's connected to a Zyro template) is pointed to Zyro via CNAME records?
If you pointed a domain to Zyro servers via CNAME records, you can create subdomains on your own.
You should do this at your current domain registrar, as your domain's DNS zone is managed from the place your domain is pointing to via nameservers. Learn how to find your domain in this article.
