Domain, hosting and business email: ownership, choice and set-up

A domain, hosting and business email are three separate parts of a website, and all three should be in the business’s own name, in accounts it can reach itself. The domain is your address, hosting is where the site’s files live, and business email means addresses such as name@yourcompany.com. Below we explain choosing an extension, the types of hosting, the basics of SSL and DNS, the options for email, and a handover checklist for changing suppliers — in plain language.

How the three parts differ

An analogy first. The domain is the address on the sign outside a building. Hosting is the building itself. Email is the building’s letterbox.

All three can be bought from the same company. But they are not the same thing, and each can be moved on its own. When a site moves to a different server, the domain stays the same. When email moves to a different provider, the site is unaffected. Knowing this makes every later change easier.

What ties them together is DNS. We will come to that a little further down.

Which extension: .com or a country code?

Both are valid and widely used. The choice depends on who you are speaking to, and which names are still free.

• .com is international. It is a familiar choice for businesses that expect clients or partners from abroad.
• A country-code extension (.co.uk, .de, .com.tr and so on) tells visitors straight away where the business is based.

Each country-code extension has its own registry and its own rules on who may register. In Türkiye, for example, .tr domains are now allocated through a central system, and since 2022 most of them — .com.tr included — no longer require trademark or trade-name documents, whilst a few, such as .gov.tr and .edu.tr, still do. Rules like these change from time to time, so check your registry’s current conditions before you register.

To protect their brand, some businesses buy both a .com and a country-code domain and redirect one to the other. It is not compulsory, but it is worth considering if you would rather nobody else had your name.

Whichever extension you choose, pick a name that is short, easy to type and not misheard when spoken aloud. Names with accented or non-Latin characters are possible, but they can cause trouble as email addresses; most businesses choose a spelling without them.

Why the domain must be in your name

Because the domain is your business’s address online. A website can be rebuilt and email can be moved — but if you lose access to the domain, you can lose the address itself.

Watch for the following:

• Registrant. The registration records should show your name or your company’s — not your supplier’s, and not an employee’s.
• Account access. You should hold the log-in for the account at the registrar where the domain sits. You can grant your supplier access as well, but the account should be yours.
• Contact email. The email address on the account should be one you will use for years — not that of someone who might leave.
• Renewal date. Domains are rented for set periods. Turn on automatic renewal and put the expiry date in a calendar.
• Transfer lock. Most registrars offer a lock that prevents unauthorised transfers. Keep it on, and switch it off only during a deliberate transfer.

On our projects, we recommend that the domain is registered in the client’s name. We cover this in what to check before commissioning a business website as well.

Which type of hosting suits you?

Hosting is the server where your site’s files are kept and served to visitors. There are three common types.

Type	What it is	Who it suits	What to watch
Shared hosting	One server shared between many sites	Small and medium business sites	Other sites on the same server can affect performance
VPS (virtual private server)	A virtual server with resources set aside for you	Special functions, high traffic, projects running their own software	Someone has to look after updates and security
Static hosting / CDN	Pre-built pages served from servers in different parts of the world	Content-led sites where speed comes first	Forms and dynamic functions need separate services

In short: shared hosting is the most common starting point. A VPS gives more control but brings more responsibility. Static hosting is often the fastest option, because the pages are prepared in advance.

We build most of our sites as static sites. That structure runs equally well on shared hosting or on a CDN. We make the choice together, based on what the site needs and the accounts you already have.

What is SSL, and why is it essential?

An SSL certificate (today, strictly, TLS) encrypts the connection between the visitor and the site. You see https:// in the address bar.

On a site without it, browsers show a “not secure” warning, and information sent through forms is not protected. Search engines also treat a secure connection as a signal.

Most hosting companies now provide certificates that renew themselves. What needs checking is that the certificate is installed, that it really does renew, and that visitors arriving at http:// are redirected to https://.

How DNS works

DNS is the address book that connects your domain to the right servers. When someone types yourcompany.com, DNS says which server that name should go to.

There are a few record types worth knowing:

• A and AAAA records point the domain at a server’s IP address. This is where the site opens from.
• CNAME records point one name at another — for example, www at the main domain.
• MX records say which server should receive email.
• TXT records hold verification and email security information.

It matters who manages your DNS records. They may sit with the registrar, the hosting company or a separate DNS service. Knowing which saves hours when the site or email is moved later. Changes also take a while to spread across the internet, so plan migration days with that in mind.

What are the options for business email?

There are three common routes:

• Google Workspace. A business address with the Gmail interface, together with calendars, shared files and video calls.
• Microsoft 365. A business address with Outlook — a familiar choice for teams that work in Word, Excel and Teams.
• Email from your hosting. Most hosting packages include mailboxes. They can be enough for a few addresses and basic use; storage, spam filtering and deliverability vary from provider to provider.

The choice depends on the tools your team already uses, how many addresses you need, and how central email is to the work. Packages and terms vary by provider, so check the provider’s own site for current details.

One suggestion: think of email separately from the website. When the site moves, you do not want email to stop as well. Email kept with a separate provider is unaffected by a change of hosting.

What SPF, DKIM and DMARC do

These three records prove to receiving servers that the email you send really comes from you. SPF lists which servers may send email on your behalf. DKIM adds a digital signature to each message. DMARC says what should happen to messages that fail those two checks, and sends you reports. All three are added to DNS as TXT records. Without them, your email may land in spam folders — or someone may send fake email in your name. The large email providers check these records more and more strictly, so they belong in the set-up from day one.

Handover checklist: what to collect when you change supplier

When you stop working with a supplier, or move to a new site, use the list below.

• The domain is registered in your name or your company’s
• You hold the log-in for the registrar account
• The domain’s renewal date and auto-renewal status are known
• You know where DNS records are managed, and have a copy of them
• You hold the hosting log-in, and know whose name the package is in
• A current backup of the site (files and, if any, the database) has been taken
• The source code or theme files have been handed over
• You hold the administrator account for the email provider
• Copies of the SPF, DKIM and DMARC records have been kept
• You know how the SSL certificate renews
• You have administrator access to analytics and search accounts such as Search Console
• Accounts for forms, maps and other third-party services are in your name

When an existing site is being redesigned, one more item joins the list: redirecting old addresses to the new ones. We explain this in detail in redesigning a website without losing SEO.

Frequently asked questions

Can I move my domain to another registrar?

Yes. Domains can be transferred from one registrar to another. This usually means removing the lock and obtaining a transfer code. Country-code domains follow their own registry’s rules, but the principle is the same.

Do I need a website to have business email?

No. Business email only needs a domain. You can use name@yourcompany.com without any site at all.

Will my email stop if I change hosting?

If your email is part of the hosting package and the move is not planned, there can be an interruption. If email sits with a separate provider and the MX records are kept, a change of hosting does not touch it.

Can I do these set-ups myself?

You can. But a small mistake in DNS or email security records can take the site or email down. If you are unsure, take a copy of the existing records before you change anything.
