The primary domain lets you use a different domain than your Mumara installation domain for publicly visible URLs — tracking links, CNAME targets for tracking domains, and public pages like web forms. This keeps your actual server URL private and shows a branded domain (e.g., tracking.yourdomain.com) in email links instead. You configure it under Settings → Primary Domain.
Setup involves a few steps: click Edit and enter the domain, configure your web server (Apache virtual host, Nginx server block, or an addon/alias domain in your hosting control panel) to serve Mumara on that domain, then add the A record shown on the page at your DNS provider, pointing the domain to your server's IP. After DNS propagates, click Confirm to validate — a green checkmark means the domain is active, while a question mark means it's still pending. After the initial confirmation, a Recheck DNS Record button is available for re-validation.
Worth knowing: do not click Confirm before the DNS record is actually in place — a failed lookup gets cached and can delay validation even after you fix DNS. Propagation usually takes 15–60 minutes but can take longer. Use a subdomain like tracking. or links. rather than your root domain, make sure your SSL certificate covers it, and configure the web server before adding DNS so the server is ready when the domain resolves.
