How to change your business email address: a small-business rollout checklist

First, be clear about what is changing

Changing your public business email address does not automatically mean migrating mailboxes or changing your website domain.

A public address is what customers and suppliers type. A mailbox is where messages are stored and managed. Your website domain is the address of your site. They may share a name, but they are separate parts of the setup.

You might keep the same website and inbox while adding a new public forwarding address. Our guide to changing business email without changing your website explains that distinction.

If you intend to move stored mail, calendars, contacts or user accounts, that is a mailbox migration project. Confirm the scope with the relevant providers rather than treating it as part of a simple public-address change.

1. Make an inventory before editing anything

Search for the old address and record every place it appears. Give each item an owner, update date and test status.

Check:

• the website, contact page and form notifications;
• Google Business Profile and other public listings;
• quote and invoice templates;
• staff email signatures and saved replies;
• business cards, flyers and fridge magnets;
• vehicles, uniforms and fixed signage;
• supplier and subcontractor records;
• booking, quoting, accounting and job-management tools; and
• key customer, property manager and account portals.

Fictional Ballarat business Summit Gate Repairs might find its old address in Xero templates, a booking tool, two technicians' signatures, a supplier account and three property-manager portals. That list becomes the rollout plan.

Customers may copy an address from old material months later. The guide to common customer email mistakes covers the places an older address can resurface.

2. Set up and test the new route first

Do not publish the new address until you know what it does in the apps and inboxes your team uses.

Send a message from an unrelated external account. Confirm that it reaches the intended inbox, attachments arrive, the right people have access and any rules or folders work as expected.

Then reply from the actual phone, webmail or desktop app each person will use. From another external inbox, inspect:

• the address shown in the From field;
• the Reply-To address;
• where the next reply is delivered;
• whether each required team member can see the conversation; and
• where sent history is stored.

Receiving through forwarding does not automatically enable sending from the new address. Read what happens when you reply from an alias or forwarded address, then confirm the current provider's verification, permission and send-as requirements.

3. Update the highest-value touchpoints

Start where new work and important messages enter the business. For many tradies, that means the website, Google Business Profile, quote template, invoice template, booking confirmation and staff signatures.

Tell staff which address to give over the phone and which address customers should see on replies. Update printed cards and vehicle graphics on a deliberate schedule rather than assuming a digital edit has reached every customer.

For fictional Coastline Pump Service, the office coordinator might update the website and quote system on Monday, test supplier and customer replies for a week, then approve the next card print run.

4. Keep the old route monitored where possible

If the current provider and setup allow it, keep the old address receiving during the transition. Assign someone to check it and note who still uses it.

Do not assume monitoring is automatic or indefinite. Confirm the provider's retention, forwarding and account settings, along with any cost or access implications.

Track stragglers by source. An old address used by one major customer needs an account update; an old address printed on a van needs a signage plan. This is more useful than changing everything again without knowing where the traffic came from.

5. Review before retiring anything

After an agreed review period, check the old inbox or route, failed form notifications, supplier records, booking tools and key accounts. Ask staff what they still see in the field.

If several people handle the address, confirm access, handover and sent-history needs before changing the setup. Shared mailbox vs email forwarding explains why routing mail to an inbox is not the same as giving a team a common working history.

Retire an old route only after the business has checked the remaining users and confirmed what the provider will remove. The timing depends on the setup; there is no universal cut-off.

A forwarding-first option

A shorter public `.au` address may be able to sit alongside your existing domain and forward incoming mail to the inbox you already use. That can make the public-address change smaller than a mailbox or website migration.

A Short Mail option remains subject to business fit, address availability, eligibility, setup requirements, provider compatibility and manual confirmation. Sending or replying from the shorter address is not automatic and must be confirmed separately.

Check whether a shorter forwarding address may fit your business before updating public or printed material.
