Domain vs hosting vs email
A clear explanation of the difference between your domain name, your website hosting, and your business email — three things that are often confused.
- Difficulty
- Beginner
When you have a website, you're actually dealing with three separate services that all work together. Many people — even experienced business owners — aren't sure how they differ. This guide clears it up once and for all.
Quick summary
Your domain is your address (yourbusiness.com). Your hosting is the server where your website files live. Your email is the service that handles messages to you@yourbusiness.com. All three use your domain name, but they are separate services, often provided by different companies.
The house analogy
The simplest way to think about it:
- Your domain name is like your street address — it's how people find you.
- Your hosting is like the land and the building — it's where everything actually lives.
- Your email is like your mailbox — it's separate from the house, even though it uses the same address.
You can change one without necessarily changing the others.
Domain names
Your domain name (like yourbusiness.com) is registered through a domain registrar — a company like GoDaddy, Namecheap, or Cloudflare. You pay a fee to keep it registered for a set term; ICANN says that term is typically between one and ten years. The registrar doesn't host your site. It holds your registration, and unless you've pointed the domain at a different DNS provider, it's also where the DNS settings live that send visitors and email to the right places.
What it does: Gives your website and email a recognizable, professional address.
Who provides it: Domain registrars (GoDaddy, Namecheap, Cloudflare, Squarespace Domains, and others).
Cost: An annual fee per domain, which varies a lot by extension. Check the registrar's own pricing, including the renewal price, which is often higher than the first year.
If someone tells you your domain is at Google
Google Domains no longer exists. Squarespace acquired all of its domain registrations and customer accounts on 7 September 2023, so a domain that used to be at Google Domains is now managed at Squarespace.
Website hosting
Your website is made of files — HTML, images, code, database content. Those files need to live somewhere so that when someone visits your domain, a server can send them those files. That's hosting.
What it does: Stores your website files and makes them available to visitors around the world.
Who provides it: Hosting companies. For WordPress sites we typically use Flywheel, WP Engine, or Kinsta.
Cost: A monthly or annual fee, and it varies widely by host and plan. Check the host's own pricing page.
See the Hosting section for everything about hosting.
Business email
Having a domain also lets you use a professional email address like hello@yourbusiness.com. But email is handled by a completely separate service — not your web host (usually). You need an email provider to handle the sending, receiving, and storage of messages.
What it does: Handles business email for your domain.
Who provides it: Google Workspace, Microsoft 365, Zoho Mail, and others.
Cost: Usually billed per user per month. Check the provider's own pricing page for current rates.
See the Email section and Google Workspace section for more.
How they all connect
They connect through DNS — the Domain Name System. Your domain's DNS records point:
- Your website visitors → to your hosting server (usually via an A record)
- Your email → to your email provider's servers (via MX records)
One name, one set of DNS settings, two entirely separate destinations. Changing your host does not move your email, and changing your email provider does not touch your website.
Read this as text
Your domain name (yourbusiness.com) sits at the top. It points to your DNS settings, which act as a switchboard.
From there the DNS settings send traffic two separate ways. The A record sends website visitors to your website hosting, where your site’s files live. The MX record sends email to your email provider, where your messages live.
The two destinations are independent. They are often different companies, and changing one does not affect the other.
This means you can change your website host without affecting your email, and vice versa — as long as the DNS records are updated correctly.
Changing hosts can break email
If you move your website to a new host and change your DNS nameservers without checking your email settings first, you can accidentally stop your email from working. Always tell us before making any DNS or nameserver changes.

Common questions
Can the same company provide all three?
Yes — some registrars offer hosting and email too, and some hosts offer email. It's convenient, but it's not always the best option for each service individually. We often recommend separating them for flexibility.
If I cancel my hosting, do I lose my domain?
No. Your domain and hosting are separate. If you cancel hosting, your website goes offline, but your domain name remains registered as long as you keep paying for it.
If I cancel my email service, do I lose my domain?
No. Your email and domain are separate. If you cancel email service, you lose access to your email, but your domain remains registered.
My domain is registered at GoDaddy but my site is on Kinsta. How does that work?
The GoDaddy domain has DNS records (or nameservers) that point to Kinsta's servers. Visitors type your domain, DNS looks up the IP address at Kinsta, and the site loads. The two services work together but are managed separately.
