Setting up a business email address on your own domain takes about twenty minutes and costs from A$4.95 per mailbox per month. There are only three moving parts: a domain you control, an email plan, and two DNS records that tell the internet where your mail lives. This is the whole process in order, with the mistakes that cost people a morning.
What you need before you start
Three things, and only the first one has any prerequisites:
- A domain name. Your email address lives on it. For an Australian business that is normally a .com.au, which requires an ABN, ACN or another eligible Australian presence under auDA's rules. Registration runs about A$10 to A$22 for the first year and A$20 to A$25 a year on renewal.
- An email plan. From A$4.95 per mailbox per month at the cheap end to about A$10 per user per month for Google Workspace or Microsoft 365. Full price table in our business email hosting register.
- Access to your domain's DNS. This is where people get stuck. If a web designer registered the domain for you, you may not have it. Sort that out first, not after.
Step 1: register the domain in your own name
If you already own the domain, skip ahead - but check whose name and email address are on the registrar account before you do. Whoever controls that account controls your email, permanently.
If you do not own it yet, register it at an auDA-accredited registrar. The domain itself is identical whoever you buy from, so judge on the renewal price rather than the first-year promo. Our guide to buying a domain name in Australia compares the registrars, and registering a .com.au covers the eligibility rules in detail.
Step 2: choose and buy the email plan
Sign up for the plan and, when it asks, give it the domain you just registered rather than letting it sell you a new one. Every provider handles this - it is the normal path.
Decide how many mailboxes you actually need before you pay, because business email is billed per user per month and the cost scales with headcount. One mailbox per person. Shared addresses like info@, sales@ and accounts@ are aliases that forward into an existing mailbox, and aliases are free on every mainstream provider. Buying a paid mailbox for each of those is the standard way to overpay.
If your web hosting plan already includes mailboxes on your domain - most Australian cPanel plans do - you can stop here. It is basic, but it works, and it costs nothing extra.
Step 3: verify you own the domain
Your provider will ask you to prove the domain is yours before it will accept mail for it. This is normally a TXT record it gives you to paste into your domain's DNS, or in some cases a file uploaded to your website.
Verification usually completes in a few minutes. If it does not, the cause is almost always that the record was added at the wrong place - see the nameserver note below.
Step 4: point the MX records at your provider
This is the step that actually moves your mail. MX records are the internet's instruction for where to deliver mail addressed to your domain. Your provider gives you a list; you add them to your domain's DNS, replacing whatever is there.
An MX record has a hostname and a priority number. Lower priority numbers are tried first. Copy the values exactly as your provider gives them, including the trailing dot if their instructions show one.
Step 5: add SPF, and then DKIM and DMARC
Getting mail to arrive is step four. Getting it to arrive in the inbox rather than the junk folder is this step, and skipping it is why new business email often lands in spam for the first fortnight.
- SPF is a TXT record listing who is allowed to send mail as your domain. Your provider gives you the value. You may only have one SPF record - if you already have one, merge the new provider into it rather than adding a second.
- DKIM signs your outgoing mail cryptographically. Your provider generates the key and gives you a record to add. Turn it on; it is a few clicks and it materially improves deliverability.
- DMARC tells receiving servers what to do with mail that fails the first two. Start with a monitoring-only policy so you can see what is happening before you start rejecting anything.
If your business also sends mail from anything else - an accounting package, a booking system, a marketing tool - each of those needs to be included in your SPF record too, or its mail will start failing.
Step 6: test it properly
Send a message from the new address to a personal account on a different provider, and reply to it. Check that:
- It arrives, and in the inbox rather than junk.
- The sender name displays the way you want it to.
- The reply comes back to the new mailbox, not somewhere else.
- Mail sent to an alias like info@ actually lands in the right mailbox.
Then set it up on the devices people will really use - phone first, since that is where most business email is read - and only then update your website, invoices, signage and Google Business Profile.
How long the whole thing takes
| Step | Typical time | What can slow it down |
|---|---|---|
| Register the domain | 5 to 10 minutes | ABN eligibility check on .com.au |
| Buy the email plan | 5 minutes | Nothing |
| Verify domain ownership | Minutes | Records added at the wrong DNS host |
| MX records propagate | Minutes to a few hours | A long TTL on the old records |
| SPF, DKIM, DMARC | 10 minutes | An existing SPF record that needs merging |
DNS changes are often described as taking 24 to 48 hours. In practice new records usually resolve within minutes, and the long wait only applies when you are changing records that were already cached with a long TTL. If you are setting up a brand new domain, there is nothing cached, and it is quick.
Moving an existing mailbox instead
If you are switching providers rather than starting fresh, the order matters and one extra step is added.
Set up the new provider and verify the domain before you change the MX records. Then migrate the existing mail across - every major provider has an import tool that pulls from your old mailbox over IMAP. Only once the mail is copied do you switch the MX records over. Doing it in the other order means mail arrives at a mailbox nobody is watching.
Leave the old mailbox open for at least a fortnight afterwards. Something always turns out to be still pointing at it.
Frequently Asked Questions
How do I set up a business email address?
Register a domain you control, buy an email plan on that domain, verify ownership with the TXT record your provider gives you, then point your domain's MX records at that provider and add an SPF record. It takes about twenty minutes of actual work and mail normally starts flowing within the hour. Add DKIM and DMARC straight afterwards or your first few weeks of mail may land in junk folders.
How do I get an email address with my own domain name?
You need two things: the domain, and an email service that hosts mailboxes on it. Buying the domain alone does not give you email. Once you have both, you connect them by adding your email provider's MX records to the domain's DNS. Many Australian web hosting plans include mailboxes on your domain at no extra cost, so check what you already have before paying for a separate plan.
How much does it cost to set up a business email address?
The setup itself is free. The running costs are a domain at roughly A$20 to A$25 a year on renewal, and an email plan from about A$4.95 per mailbox per month. A sole trader with one mailbox is looking at under A$100 a year all up. See our business email price register for every plan.
Can I create a business email for free?
Partly. Zoho Mail's free plan covers up to five users on one domain, but access is web-only with no IMAP or POP, so it will not work with Outlook or Apple Mail. You still have to pay for the domain. And many web hosting plans already include mailboxes at no extra charge, which is the most common genuinely free route.
Why is my new business email going to spam?
Almost always because SPF, DKIM and DMARC are not set up, or SPF is set up but does not include everything that sends on your behalf. A brand new domain also carries no sending reputation, so volume ramps slowly at first. Add all three records, send at a normal human pace for the first couple of weeks, and it settles.
Where do I add MX records?
Wherever your domain's nameservers point, which is not necessarily your registrar. Check the nameservers on your domain first: if they point at your web host, add the records there; if they point at Cloudflare, add them at Cloudflare. Records added in the right format but the wrong place fail silently and look exactly like a typo.
Can I keep my existing emails when I switch providers?
Yes. Every major provider has an import tool that copies your old mailbox across over IMAP. Do the import before you change the MX records, not after, and leave the old mailbox running for a fortnight afterwards - something is always still pointing at it.
Do I need a .com.au or will a .com do?
Either works technically. A .com.au signals to Australian customers that you are actually here, and it requires an ABN or ACN to register, which is exactly why it carries that signal. A .com can be registered by anyone anywhere. Most Australian businesses register the .com.au as their primary address.
