You will need to own a domain name and have access to its DNS settings. If you want to purchase a domain, you can go here: https://d.pr/QJrI8c. If you already own one, you will need to add it to Instapage and go into your domain registrar’s DNS settings and create a new CNAME record.
You can find the step-by-step instructions for creating a CNAME record and pointing it to our server address as seen here: https://d.pr/QZoyvs
After you have done that, you will need to add your new subdomain to the Domains section of your Instapage workspace by following the instructions here: https://d.pr/x1u6c2
Based on the selected plan, customers are subject to different limitations on the number of subdomains available for publishing. These limits can be checked in My Account Admin >> Subscription section.
Go to the page you want to publish, click on Publish page in the slideout or on Publish inside the builder, then click on Custom Domain, select your URL from the dropdown, and publish the page.
How do I unpublish a page?
Click on URL settings, and you will be presented with the option to Unpublish the page.
