So I have made a landing page on Instapage and i want to connect it by using a CNAME to my current domian that I bought through shoppify. I have no idea where to start with this, any info would be helpful!
In order to change or add a CNAME to the domain you purchased via Shopify, you'll need your OpenSRS credentials. Shopify is a domain reseller and OpenSRS is the domain provider, so you'll need access to that account in order to make DNS setting changes. You can gain access to your OpenSRS account by getting in touch with us at email@example.com to request access.
Once you've had your login credentials forwarded to you, you can use this guide to access your CNAME records.
