What's the difference between a domain, hosting and email?
Facts checked Oct 9, 2026
Your domain is your address, hosting is the building your website lives in, and email is the mailbox. Often three bills, sometimes one company.
Side by side
| What | It's like | What it is | Who you pay, and how often |
|---|---|---|---|
| Domain name | The street address | The name people type, like yourwebsite.com. You rent it; you never own it outright. | A domain company (a registrar), for 1 to 10 years at a time, usually yearly |
| Hosting | The building | The computers that hold your website's pages and pictures and send them to visitors. | A web host, or your website builder (hosting is part of the plan), monthly or yearly |
| The mailbox | The service that receives and keeps mail sent to you@yourwebsite.com. | An email service, often per person a month. Sometimes included with hosting or the domain. |
The domain ties the other two together. Its DNS settings (the internet's address book) hold one set of records that point to your website, and another that point to your email. That's why a domain can sit with one company, the website with a second and email with a third. See How to connect your domain to your website and Get an email address with your domain name.
What happens if one lapses
- The domain lapses
- Your website and your email both stop, even if hosting and email are paid up, because nobody can find them. You usually get a few weeks to rescue it, at a price. See Domain name expired?
- Hosting lapses
- Your website goes offline: visitors see an error or a holding page. Email keeps working if it's with a different company. The host may delete your site's files after a while, so ask how long, and keep your own backup.
- Email lapses
- Mail to your addresses stops arriving and may bounce back to the sender. Your website keeps working. Old mailboxes may be deleted after a while, so ask how long.
If all three are with one company, one missed payment can stop all three. Check what each bill covers.
Do I need hosting if I have a domain?
- Yes, for a website. A domain on its own is only an address. Without hosting, visitors get an error or a "parked" page from your domain company.
- Not for email alone. You can use a domain only for email, with an email service and no website.
- On a website builder, hosting comes with the plan. You don't buy it separately.
- Do I need a domain on a website builder? No: builders give you a free address on their own name. But your own domain is the address that stays yours if you ever move.
Who do I pay now?
- Look it up. Who hosts this website? names your domain company, your web host and your email service, and the date the domain runs out.
- Check your statements. Search your card and bank statements, and your email, for "domain", "hosting", "renewal" and "invoice".
- Check whose name each account is in. Each should be in your business's or organization's name, with an email address you read. If someone has left, Taking over a website has the checklist.
- Write it down. One line each: the company, what it's for, the renewal date, the price, and who has the log-in.
A "free domain for the first year" renews at the normal price after that. Check the renewal price, not just the first one.
