How to Create a Professional Email Address

To create a professional email address, register a domain name for your business and attach an email hosting plan — such as Professional Email or Microsoft 365 — so you can send and receive mail as name@yourbusiness.co.nz. The whole process takes four steps: choose a domain, pick an email platform, decide your address format, and set up the DNS records that make your mail deliverable. This guide walks a NZ business owner through each step, including how to switch over without losing a single message.

Why name@yourbusiness.co.nz beats a free address

A custom-domain email address does three jobs a free Gmail or Outlook.com address cannot. First, it signals that you are an established business: customers, suppliers and banks all read plumber.dave.1987@gmail.com differently from dave@davesplumbing.co.nz, and an invoice sent from a free address is more likely to be questioned — or mistaken for a scam, since scammers overwhelmingly use free addresses.

Second, it keeps your business email under your control. Mailboxes on your own domain belong to the business, so when a staff member leaves, you keep the mailbox, the history and the customer relationships. Email sent from someone's personal account walks out the door with them.

Third, every message quietly advertises your domain. Anyone who receives your email can find your website by looking at the part after the @ — free marketing you give up entirely when the answer is gmail.com.

Step 1: Register a domain that matches your business

Your email address can only be as good as the domain behind it, so start there. For a New Zealand business, .co.nz remains the default choice and the one customers expect; the shorter .nz version is also available and worth registering alongside it so nobody else picks it up. Match the domain to your trading name where you can, and apply the over-the-phone test: if you cannot read the address out loud without spelling it twice, choose something shorter.

Register the domain through a provider that can also manage your DNS and email, because the setup steps later in this guide are far simpler when one party controls all three. You can check availability and register through our domain registration and web hosting service — and even if your website is months away, register the domain now. Email can run on a domain long before a website exists, and the name you want will not wait for you.

Step 2: Choose your email platform

With the domain sorted, you need somewhere for the mail to actually live. For most small businesses the decision comes down to two options, and Solution Squad sells both through the workspace section of our online shop.

Professional Email gives you a mailbox, calendar and contacts on your own domain, with webmail plus support for Outlook and the standard phone mail apps. It suits sole traders and small teams whose main need is simply reliable email at a low per-mailbox cost.

Microsoft 365 gives you the same custom-domain mailbox through Exchange Online, plus the tools around it: Word, Excel and PowerPoint, Teams for calls and chat, and OneDrive and SharePoint for file storage and sharing. If your team collaborates on documents, runs video meetings or needs properly licensed Office applications, it is the better fit — and as a Microsoft Partner we can set up and support it. A useful rule of thumb: start with Professional Email if email is all you need today; you can move to Microsoft 365 later as the business grows, keeping the same addresses.

Step 3: Decide your address format before you create mailboxes

Pick a naming convention on day one, because retrofitting one later is painful. For people, firstname@ is the cleanest format for a small business (sarah@), moving to firstname.lastname@ once you have enough staff for names to collide. Avoid nicknames, birth years and numbers — the things that make free addresses look unprofessional will do the same on your own domain.

Alongside personal addresses, set up role-based addresses for functions rather than people: accounts@ for invoicing, hello@ or info@ for general enquiries, support@ if you handle service requests. Most email platforms let you create these as aliases — extra addresses that deliver into an existing mailbox at no extra cost — which is usually all a small business needs. Create a separate paid mailbox only when a different person needs to own it or the mail genuinely needs to be kept apart.

One thing to avoid: a catch-all address that accepts mail sent to anything at your domain. It sounds convenient, but in practice it mostly collects spam and makes typos invisible.

Step 4: Set up the DNS records that make email deliverable

This is the step that separates a professional setup from one that lands in junk folders. Four DNS records on your domain control where your mail goes and whether other servers trust it. MX records direct incoming mail to your email provider. SPF lists the servers allowed to send mail for your domain. DKIM adds a cryptographic signature proving a message really came from you. DMARC tells receiving servers what to do with mail that fails those checks — and helps stop criminals sending fake email that appears to come from your domain, a common starting point for invoice fraud against NZ businesses.

If the same provider manages your domain, DNS and email, these records are typically configured for you during setup. If your domain sits with one company and your email with another, they need to be added by hand, and mistakes here are the usual cause of "my emails keep going to spam". Getting SPF, DKIM and DMARC right is as much a cyber security measure as a deliverability one, so it is worth having someone check them even on a working setup.

Switching over without losing a single email

If you are moving from a free address, do not simply abandon it. Keep the old account alive for a transition period and set it to forward everything to your new address, with an auto-reply telling regular contacts where to reach you now. Then work through the boring but important list: update the sending address in your invoicing and accounting software, change the contact address on your website and Google Business Profile, refresh your email signature, and update any logins that use the old address for password resets.

Secure the new mailbox from day one — a strong unique password and multi-factor authentication are non-negotiable for an address your invoices come from. Rather hand the whole switch over? Ask us and we'll run the migration for you.
