Domain, hosting and business email: what is the difference?

Your domain is the name people use to find your business online. Website hosting serves the pages they visit. Business email provides the mailboxes your team uses at that domain. You can buy these together, but paying for one does not automatically mean the others are included.

For South African small and medium-sized businesses, understanding that distinction makes website quotes easier to compare. It also helps you ask the right questions before a redesign, especially when the existing website and email share a hosting package.

What each service actually does

• Domain registration: keeps a chosen name registered for a defined period through a registrar. Record the renewal date and the business contact responsible for it.
• Website hosting: provides the environment that makes your website available online. A website builder may include this within its subscription; another kind of site may need a separate hosting plan.
• Business email: provides mailboxes using your domain, with the storage and features offered by your email service. Confirm whether the package includes mailboxes or only forwarding to another address.

A designer’s work is another part of the picture: planning and building the pages, arranging content and setting up the agreed visitor journeys. Ask which ongoing services the design quote includes, which you will pay separately and who manages them after launch.

South African provider Domains.co.za explains the same core distinctions in its guide to email hosting. Package names vary, so compare the actual inclusions rather than relying on the word “hosting”.

How the services connect

The connection is managed through DNS, short for Domain Name System. Think of it as a set of directions for your domain: some entries point visitors to the website, while others direct email to the mail provider. The company managing DNS may be different from the registrar, website host or email provider.

You do not need to choose technical record values yourself. Ask the person handling the setup to identify which provider supplies each service and which settings must be preserved. Cloudflare’s DNS record reference explains that MX records direct email delivery and that separate records are used for email authentication.

Do you need one provider for everything?

No. The useful question is whether the arrangement is clear and manageable for your business. One supplier can simplify billing and support. Separate services can let you keep an existing email setup while changing the website platform. Either arrangement needs someone who understands how the parts connect.

Before choosing, ask who handles a problem that crosses services. If a website form is not reaching your inbox, will the designer investigate the form, will the email provider check delivery, and who coordinates the response? Avoid an arrangement where each supplier assumes another person owns the task.

Also ask what happens when you leave. Confirm how you would obtain your website content, move the domain or retain your email service. Export and transfer options depend on the platform and agreement; do not assume every website can be moved unchanged to another host.

What to ask for in a quote

Request a short breakdown you can keep with your business records. For each service, ask for the supplier, account holder, billing frequency, renewal amount or how it is calculated, and the person responsible for support. Confirm whether quoted amounts include VAT rather than assuming they do.

• Domain: the exact name, registration or renewal period, renewal contact and who can manage it.
• Website: the platform, hosting arrangement, access provided, and what backups or recovery support are included.
• Email: the number of mailboxes, storage allowances, any forwarding addresses and whether moving existing messages is included.
• Ongoing work: who updates website content, who maintains the platform and how additional changes are quoted.

What to check before moving your website

Start with an inventory of the current domain, website, DNS and email providers. Include all active mailboxes and forwarding addresses, plus connected booking or payment services. Ask the new designer to explain what will change and what will stay with the existing provider.

Do not cancel a hosting package just because the new website is ready. First confirm whether that package also supplies your email or DNS. If it does, agree how those services will continue before cancelling anything.

Ask the person managing the move to preserve the required DNS records and prepare a recovery plan. If the nameservers are changing, the new DNS setup needs the relevant records before the switch. Cloudflare’s DNS setup guidance specifically advises reviewing records and adding missing ones before changing nameservers.

Agree a check after the change: open important website pages on a phone and desktop, send and receive a test email with an outside address, and confirm that a test website enquiry reaches the intended inbox. If mailboxes are also moving, check access to the agreed existing messages. A form’s success message alone is not proof of delivery.

Keep a simple handover record

At handover, ask for a service list with account owners, renewal dates, support contacts and the agreed access arrangements. Confirm that the business can reach the relevant accounts through its authorised people, and assign someone to keep the record current.

The aim is practical continuity: knowing what you pay for, who can help and what needs checking when something changes. Once those responsibilities are clear, it is much easier to commission a website without leaving the domain or inbox as an unanswered question.
