What is a domain?
Plain-language explanation of domains, ownership, and how they relate to email with Reloop.
A domain is the human-readable name for your brand on the internet — for example acme.com or shop.acme.com.
Domain vs website vs email
| Concept | Example | Meaning |
|---|---|---|
| Domain | acme.com | The name you registered |
| Website | https://acme.com | Pages hosted somewhere (Vercel, Netlify, WordPress, …) |
| Email address | hello@acme.com | Mail identity that uses the domain after the @ |
Reloop is email infrastructure, not a website host. Your site can stay on Vercel, Netlify, WordPress, or anywhere else — Reloop only needs permission (via DNS) to authenticate and deliver mail for that domain.
Who “owns” a domain?
Ownership is recorded at a registrar (GoDaddy, Namecheap, NameSilo, Cloudflare Registrar, Squarespace, etc.). You renew it yearly (or longer). Owning the domain means you can:
- Change nameservers (who answers DNS questions)
- Create DNS records (or point NS to another DNS host that does)
- Prove control to services like Reloop
Root domain vs subdomain
- Root (apex):
acme.com - Subdomain:
mail.acme.com,news.acme.com,send.acme.com
You can connect the root, a subdomain, or both to Reloop.
Pros of a subdomain
- Existing MX on the root stays untouched
- Easier SPF story if the root already has a long SPF
- Separate sending reputation from corporate mail
- Clearer mental model: “product mail lives on
mail.”
From addresses look like hello@mail.acme.com unless you also configure other identities — plan branding accordingly.
Pros of the root domain
- Addresses look like
hello@acme.com - Fewer labels to manage
- Fine when Reloop is the primary mail platform for that domain
What Reloop needs from you
- A domain (or subdomain) you control
- Ability to publish DNS records at the host that serves that domain’s nameservers
- Verification in the Reloop dashboard
