Email hosting vs web hosting: what each does and how to choose
Both services sit behind the same domain name, but they do different jobs and fail in different ways. This guide shows how to tell them apart and when to split them.
The short answer
Web hosting stores and serves your website's files so people can view your pages. Email hosting provides the mailboxes that send, receive and store your business email on your own domain. They are separate services that may come from one company or two. Many small businesses start with both together and separate them once email becomes essential.
Email hosting vs web hosting in one table
Email hosting vs web hosting is a common point of confusion, because both services sit behind the same domain name. The table sets out how they differ.
| Question | Web hosting | Email hosting |
|---|---|---|
| What does it do? | Stores your site's files and data and serves pages to visitors | Stores mailboxes and handles sending and receiving |
| Who uses it? | Visitors to your website | Your staff and everyone who writes to them |
| What does a failure look like? | The site is slow, shows an error or cannot be reached | Messages bounce, arrive late or cannot be read |
| Which DNS records point to it? | A or CNAME records | MX records, plus TXT records for sender checks |
| What does its size depend on? | Pages, media, traffic and the software the site runs | Number of mailboxes, storage per mailbox and attachments |
| What does moving it involve? | Copy the files and database, test, then repoint the domain | Copy each mailbox's messages, then change the MX records |
| Who normally manages it? | A developer, an agency or the business | Whoever administers staff accounts, often the owner or an office manager |
What web hosting does
Web hosting is the rented server space that holds your website and delivers it when a browser asks. It runs the software that builds your pages, such as a CMS, and stores the database and the uploaded images. Several types exist, from shared servers to cloud set-ups, and the right one depends on the platform and the traffic. When the web host has a problem, your site is affected. Your mail is not, if it lives elsewhere.
What email hosting does
Email hosting runs the mail side of your domain. It provides the mailboxes where messages are stored, receives incoming mail for the domain, sends outgoing mail, filters spam and lets staff read messages in webmail or in mail apps. Business services add administration: creating and removing accounts, shared mailboxes, aliases such as an enquiries address that forwards to several people, and rules about who may log in and how.
The result is an address on your own domain. The domain only supplies the name. Messages arrive because your MX records point to the email host, and your outgoing mail is more likely to be trusted when SPF, DKIM and DMARC records are in place.
Is email hosting the same as web hosting?
No. They are different services that are often sold together. Many hosting companies include mailboxes with a website plan, which makes the two look like one product. Underneath, a website visit and an email follow different routes. A browser looks up your A or CNAME record and goes to the web server. A sending mail server looks up your MX record and goes to the mail server. The two records can point to different companies, and that is what allows you to split the services.
Can I use my website host for email?
Yes, if your plan includes mailboxes. For a very small business with a few addresses and light mail, that can be adequate. It is simple, there is one supplier, and the set-up is often a few clicks. The drawbacks are about control and risk, and how much they matter depends on the host and the plan.
- Mailbox storage and attachment sizes vary by plan, so check the current documentation before relying on it for years of mail.
- Administration is often basic. Adding a person may be easy, while controlling access, reviewing logins or sharing a mailbox may not be.
- Mail on a shared server can be affected by what other accounts on that server do. Whether this happens depends on how the host runs its servers.
- Your website and your mail then share one supplier, one login and one point of failure.
- If you ever move the website, the mailboxes need a plan of their own.
Why would I keep email separate?
The strongest reason is that the two services change at different speeds. A website gets rebuilt, moved and redesigned. Email is the thing nobody notices until it stops. Keeping them apart means a website project cannot break the mail.
Here is how that plays out in practice:
- During a rebuild or platform change, such as the move described in WordPress website vs custom website, the site is in flux for days. With mail hosted elsewhere, the mailboxes are untouched.
- If the web host has an outage, customers can still email you, and your alerts can still reach you.
- When someone leaves the business, you can close their mailbox without touching the website's access.
- Logins are separate, so one compromised website password does not expose every mailbox.
The cost of separating is real. You have two suppliers, two logins and DNS records that must be exactly right. Whether the trade is worth it depends on how much the business relies on email and on your budget.
Which arrangement suits which business
| Situation | Arrangement that usually fits | Why |
|---|---|---|
| A sole trader with one or two addresses and light mail | Mailboxes from the website host can be enough | One supplier is simple. Revisit it if mail becomes busy. |
| A small team that quotes and invoices by email | Separate email hosting | Staff accounts, shared mailboxes and account recovery matter more than saving a supplier |
| An online shop that relies on order and support emails | Separate email hosting | A website problem should not stop customers' replies reaching you |
| A business planning a rebuild or platform move | Separate email before the project starts | Takes mail out of the project's risk |
| A site on a website builder or hosted store platform | Check whether the platform offers mailboxes; if not, use a dedicated email provider | The platform hosts the site, not necessarily the mail. Check its current documentation. |
Moving the website without losing your email
The classic failure is cancelling the old hosting account without noticing that it also held the mailboxes. Everything stored there goes with it, and so does the ability to receive new mail.
- Find out where your mail is hosted now. Look at the MX records for your domain, or ask whoever set it up.
- If the old hosting account holds the mailboxes, decide where they will live afterwards and copy the messages across before cancelling anything.
- Change the website's A or CNAME record only. Leave the MX records alone until the mailboxes have moved.
- Send test messages in both directions from an address outside your domain.
- Keep the old account until you are sure nothing is still arriving there.
A rebuild has its own timeline, and mail changes belong in the same schedule. The guide to how long it takes to build a website describes the stages around launch.
Monitoring, ownership and who sees your address
A monitor that checks your website says nothing about your mail. Add a recurring test message, and send alerts to an address that does not depend on the service being watched. The guide to website uptime monitoring covers what to check and who should be alerted.
Ownership matters here too. The domain registration sits behind both services, so the registrar account should belong to the business, not to the person who set up the website.
Your address is also seen outside your inbox. An editor or partner replying to a pitch sees the domain it came from, and a named address on your own domain gives them something to reply to. If you plan to approach the press, the guide to digital PR and press mentions explains how mentions are earned. Decide too who writes the wording on the contact page and in automatic replies. The guide to who writes what in website copywriting lists the usual split.
What to ask your host or developer
- Where is our email hosted today, and where do the MX records point?
- Does the web hosting plan include mailboxes, and what happens to them if we move the site?
- Who holds the logins for the domain, the web host and the email host?
- How are SPF, DKIM and DMARC set up for our domain?
- What is the plan for copying existing messages before any move?
Put the answers in the project brief or contract so nothing is assumed. If you want a team to plan a hosting move alongside a build, the website development page from Liftup Technologies describes what it covers.

Questions and answers
Is email hosting the same as web hosting?
No. Web hosting stores your website and serves it to visitors. Email hosting stores your mailboxes and handles sending and receiving. Many companies sell both in one plan, which is why they look the same, but they use different DNS records and can be split between suppliers.
Can I use my website host for email?
Yes, if the plan includes mailboxes. It suits a very small business with light mail. Check the current documentation for storage, sending limits and admin controls, and think about what happens to the mail if you later move or rebuild the site.
Why would I keep email separate from my website?
So a website outage, move or rebuild cannot take your email down with it, and so each service has its own logins and settings. The trade-off is two suppliers to manage and DNS records that must be correct.
Do I need separate email hosting?
Not always. A very small business with light mail can use mailboxes from its web host. Separate hosting is worth considering when email is essential to trading, when several people share mailboxes, or when you plan to move or rebuild the website.
What happens to my email if I change web hosts?
Nothing, if your mailboxes are hosted elsewhere and you change only the website's records. If the old host also held the mailboxes, copy the messages and move the MX records before you cancel the old account.
Can I have business email without a website?
Yes. You need a registered domain and an email host, and you point the domain's MX records at that host. A website is optional. Add the sender records your email provider asks for so your messages are trusted.
