# Domain & Email

Every project starts with a **Temporary site address** ending in `superdev.run`. Click the address to open your site in a new tab, or use **Copy link** to share it while you set up your own domain.

Once a custom domain is verified and has no website DNS conflicts, **Domain & Email** hides the temporary address. It appears again if no custom domain is ready.

Open **Domain & Email**. The easiest path is to [buy a domain through Buildy](/docs/domains-email/buy-a-domain). Buildy connects your website and sets up email sending and your first included inbox. If the project already has an inbox, Buildy keeps it.

The page shows your connected domain and compact **Email sending** and **Email inbox** sections. Open a section to see its status, DNS records, and any action needed. Domains and email need a paid plan.

A yellow dot beside **Domain & Email** means a custom domain or its email setup needs attention. Open the page to see what is still being set up, which records need changes, or which check needs another attempt. Projects with only a temporary address do not show a setup warning.

After you connect an external domain, the page focuses on finishing its setup. **Connect your website** stays open while website DNS needs attention. Email sending uses one record list with a **Check DNS** button.

Own a domain already? [Connect your existing domain](/docs/domains-email/connect-your-own-domain). You manage its DNS settings. Inbox setup stays manual, so connecting the domain does not create an inbox or move your existing email.
