Australian email hosting for business.
Unlimited addresses. Australian servers. From $8/month.

Yes. All Stack2 email hosting runs on Australian infrastructure. Your emails, attachments, and backups stay onshore — no data leaves Australia.

Yes. Stack2 is an Australian-owned email provider, hosting business email on Australian infrastructure since 2008. Unlike the big global providers, your mailboxes, attachments and backups stay onshore in Australia, and support comes from our own engineers — not an overseas help desk.

For an Australian business, the things that matter most are deliverability (DKIM and SPF configured for you, so your domain is properly authenticated and far less likely to be flagged as spam), data kept onshore in Australia, daily backups, and predictable pricing without per-mailbox fees. Stack2 includes all of these on every plan.

Unlimited. You are buying a shared storage pool, not a per-domain plan — create as many addresses, aliases, and forwarders as you need across as many domains as you own, at no extra cost. The plan storage is shared across all your accounts.

Yes. We can migrate mailboxes from cPanel, Google Workspace, Microsoft 365, and most other providers. Get in touch and we will put together a migration plan before you switch — including DNS cutover timing so you don't lose mail in transit.

DKIM is a cryptographic signature that proves your email genuinely came from your domain. Without it, outbound mail is far more likely to land in spam or be rejected outright. Stack2 configures DKIM and SPF on every account — you do not need to touch DNS yourself.

Any client that supports IMAP or POP3 — Outlook, Apple Mail, Thunderbird, iOS Mail, and Android all work. Webmail is also included. We provide the IMAP/POP3 server settings so setting up a new device is straightforward.

No, you bring your own domain — but you're not limited to one. Email hosting is billed per storage pool, not per domain, so a single plan covers unlimited addresses across as many domains as you own. If you don't have a domain yet you can register one with Stack2 or point an existing one at us.

Migration is a separate, quoted service — it's priced per engagement rather than included free, because the work depends on your provider, mailbox count, and how much mail you're moving. Device setup is manual: we give you the IMAP/POP3 server settings to add your account to Outlook, Apple Mail, or your phone. There are no auto-configuration profiles.

It's priced per engagement, based on your current provider, the number of mailboxes, and how much mail is being moved. Request a free migration assessment and we'll send a plan and a quote for the work before you commit — with no obligation to switch.

A migration is planned so mail keeps flowing. We copy your existing mail across first, then schedule the DNS cutover so new messages arrive at Stack2 without a gap. We'll recommend a cutover time as part of your migration plan.

Yes. An IMAP migration brings your messages and folder structure across, so your mailbox looks the same after the move.

Your mailbox contents — messages and folders — migrate across. Whether contacts and calendars can come with them depends on your current provider and setup, so we'll confirm exactly what can be moved when we scope your migration.

We keep an eye on your pool and let you know before it becomes a problem. Moving up to a larger plan is a storage change on the same platform — there's no re-migration and no new setup, so you keep sending and receiving throughout.

Yes. Every price shown is in AUD and includes GST — the amount you see is the amount you pay. There's no setup fee, and you can choose monthly or annual billing.

Mailboxes are backed up daily and kept for 30 days, so you can go back to an earlier copy if something is deleted or overwritten. Restore time depends on the size of the mailbox, but most restores are done within an hour — at no extra charge.

Stack2 email is the right fit if you want straightforward business email at a flat monthly cost and don't need shared calendars, Teams, or Office desktop apps. It's also popular with web agencies managing email for multiple client domains. If your team needs the full Microsoft 365 productivity suite, see our Microsoft 365 plans.
