The short answer
A domain is your web address (like yourbusiness.co.nz). Hosting is the computer space where your website's files live so people can see them. Email is your business mailbox, the thing that lets you send and receive messages at you@yourbusiness.co.nz.
They are three separate things, and you usually buy them separately. Knowing that up front saves a lot of confusion.
Why it matters to a small business
Most delays in getting a business online come from mixing these three up. People sign up for one thing, expect it to cover the others, and then stall when something is missing.
It can also cost you money. You might pay for hosting before you have a domain to point at it. Or you might pay for a package that bundles things you don't need yet. Sorting out what each piece does makes it easier to see what you are actually buying.
And it affects how professional you look. An address like yourbusiness.co.nz in your email and on your website tells customers you are established. A generic personal email address on a quote can make people hesitate.
How it actually works
Think of a shop in Hamilton.
- The domain is the street address. It tells people where to go.
- The hosting is the building. It holds everything customers come to see.
- The email is the mailbox. It handles the messages coming in and going out.
An address with no building on it leads nowhere. A building with no address is hard to find. A mailbox is a separate fixture again, even though it carries the same street address.
Domain
You register a domain, usually for a year at a time, and renew it to keep it. You are not buying it outright. You are holding the right to use that name. The domain itself holds very little. Its main job is to carry settings that say where visitors should be sent.
Hosting
Your website is a set of files: pages, photos, text. Hosting is a server, a computer that is always connected to the internet, that stores those files and shows them to visitors. When someone types in your domain, the domain's settings send them to your hosting, and the hosting delivers your site.
Email is its own service. It uses your domain name for the part after the @ sign, but the mailboxes themselves can live somewhere completely different from your website. The domain settings also carry instructions about where to deliver your email.
How they connect
The domain sits in the middle. It routes website visitors to your hosting, and it routes incoming email to your mailbox service. Hosting and email don't need to know about each other.
Here is an illustrative example. A plumber in Whangarei registers a domain, puts her website on hosting, and sets up a mailbox service. The domain sends website visitors to the hosting and sends her email to the mailbox. If she later moves her website to a different host, she changes the domain's settings, and her email carries on as before.
What it is NOT
- You don't need all three on day one. You can have a domain and email with no website yet. Plenty of new businesses start that way, so they have a proper address on their quotes while the site is still being built.
- They don't have to come from the same seller. Many people keep them together for convenience, but you can mix and match. Just keep a note of where each one is and when it renews.
- A domain is not a website. Owning a domain only means you hold the name. Until you add hosting and put a site on it, there is nothing for visitors to see.
- Hosting does not automatically include email. Check this before you buy. With our hosting, for example, mailboxes are not included.
Where to start
Do it in this order.
- Domain first. It is the foundation. Everything else hangs off it, and a good name can be taken by someone else while you are still deciding. Choose something short, easy to spell and easy to say over the phone.
- Hosting second. Once you have a name, your website needs somewhere to live. Pick a plan that suits where you are now. You can move up later as the site grows.
- Email third. Once the domain is yours, set up mailboxes so you can send from an address that matches your business.
If you are comparing options, Rapid Ready Ai sells all three separately: hosting from US$4.99 a month, domains on their own, and Professional Email as an add-on. Backups are a separate add-on too, so it's worth working out what you need before you buy.
Whoever you buy from, write down where each piece is registered, the login for each, and the renewal dates. That one page of notes prevents most of the problems that show up later.
