What is a domain name and how does email use it

Key points

• Domain = your address on the internet (yourcompany.com)
• Email uses your domain after the @ (you@yourcompany.com)
• You control it via DNS records
• Owning your domain means owning your email identity

How to do it

1. Register a domain at any registrar (Namecheap, Cloudflare, etc.)
2. Verify you control it (DNS or file verification)
3. Point MX records at your email provider
4. Create mailboxes on your domain

Common mistakes

• Registering a typo-squatted or unfamiliar domain
• Not enabling auto-renew (domain loss)
• Using the registrar's default parked page
