Voice doesn't manage email addresses for domains - just the website.

The registrar where you buy your domain is likely to offer email services - either a mailbox or forwarding to your existing email accounts. This may be included with your domain or be a small additional charge.

You can also host email using Google Workspace or Microsoft Outlook, or another hosting provider, though they will charge for this service.

(from a technical point of view, when you configure the DNS for your domain, the A record is used to go to the website, and MX record used for email, and these can point to different services)
