Domain & Email

Buy or connect a domain, check DNS status, and manage email sending and your inbox.

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. 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. You manage its DNS settings. Inbox setup stays manual, so connecting the domain does not create an inbox or move your existing email.
