Google Workspace brings custom-domain Gmail, Drive, Calendar, Docs and Meet into one managed business account. It suits teams already comfortable with Google tools and wanting email and shared files under a single subscription.

• Business Starter includes pooled storage calculated per user; higher editions increase storage and add administrative, meeting and security capabilities. Check the total pooled allowance and any limits that matter to your team.
• Teams can co-edit files in a browser and control access through shared folders and admin settings. Familiar apps simplify onboarding, although domain and migration planning are still required.
• A trial lets you test mailbox setup, sharing and mobile access. Compare monthly and annual commitments, the cost per seat, renewal terms and whether your preferred third-party tools connect properly.

Our view: A practical all-round choice for teams who collaborate in Google apps. Test a real mailbox migration and shared folder before committing.

Microsoft 365 combines custom-domain business email, OneDrive storage and familiar Office tools in a managed subscription. It suits teams already using Outlook, Word or Excel and wanting email and shared files within one business environment.

• Business Basic with Teams is the entry plan in our comparison. It includes web and mobile versions of Word, Excel, PowerPoint and Outlook, custom business email and 1 TB of cloud storage per user.
• Teams supports chat and online meetings, while SharePoint provides team sites for sharing files and information. A without-Teams edition is also available, so check which version you choose.
• Business Standard adds desktop Office apps. Use the available trial to assess document compatibility, mailbox migration and permissions; confirm Australian pricing, GST, billing commitment and the total number of paid users.

Our view: A strong all-round option for Microsoft-focused teams; choose the edition around your actual app and collaboration needs.

Zoho Workplace combines business email with WorkDrive file storage and a suite of writing, spreadsheet, presentation, chat and meeting tools. It is worth considering when you want an integrated office setup without relying on Google or Microsoft.

• Workplace Standard is the entry suite in this comparison. Zoho also sells mail-only plans; a cheaper mailbox subscription may exclude team file storage.
• Team storage can be shared across an organisation rather than allocated in the same way as a personal drive. Review the allowance for your exact team size, together with mailbox limits and any extra storage charges.
• Use the trial to check editing compatibility with existing documents, email migration, mobile apps and the admin console. Confirm local currency, taxes and the billing term at checkout.

Our view: Good value to investigate for a small team needing both email and collaborative files; the right edition matters more than the headline price.

Proton for Business offers business email, calendar and encrypted file storage within its wider privacy-focused product family. It is suited to organisations that place a high value on controlling access to correspondence and files.

• Choose a Workspace plan when you need both Mail and Drive; a mail-only edition should not be compared with a full office suite. Storage, domains and security features vary across the plans.
• Proton also offers document and team tools on selected plans. Check how external sharing, collaboration and migration work for your particular workflow, especially when partners use conventional email and cloud platforms.
• The trial gives a way to test administration and daily use before moving a domain. Check per-user costs, annual discounts, any extras and the precise storage allocation shown at checkout.

Our view: A strong privacy-led option, provided its collaboration workflow fits the files and outside partners your team uses every day.

Fastmail concentrates on email, calendars and contacts for people and businesses. It supports custom-domain addresses and a clean mail experience without asking a small business to buy a large office suite.

• Admins can manage users and addresses, while employees can use web, mobile or compatible desktop clients. Its sharing and productivity integrations are helpful, but Fastmail is primarily an email service.
• Plans may include limited file storage for attachments and personal files; that is different from a full team drive. Budget separately for collaborative documents or cloud storage if your business needs them.
• A free trial is useful for checking migration, aliases, calendars and delivery to common customers. Compare plan storage, user pricing, currency and the cost of adding more mailboxes.

Our view: An appealing specialist choice if reliable custom-domain email is your main need and you are happy to choose separate file tools.

VentraIP provides dedicated business email hosting with Australian-based support and, according to its published product information, email data stored on servers in Australia. It suits a business that prefers local help with domain email.

• Its email product includes filtering, backups and mailbox storage options. Choose the dedicated email plan you actually need; VentraIP also offers Google Workspace and Microsoft 365 as separate products.
• The company advertises migration assistance, which can be valuable when moving an established domain. Check the migration scope, mailbox size, aliases, device setup and support hours for your selected service.
• This comparison treats VentraIP as an email host, not a stand-alone team file drive. Compare annual and monthly pricing, the number of mailboxes and any extra storage before ordering.

Our view: A clear Australian option for businesses prioritising local email support and data location. Confirm the exact mailbox plan and migration process.

DreamIT Host sells dedicated email hosting with Australian servers and support. Its plans are built around shared storage and a number of mailboxes, which can suit a business with several addresses under one domain.

• Email-only and email-with-calendar configurations appear on its product page. Check which version you select, as mailbox count, storage, calendar functions and underlying control panel may differ.
• Webmail, filtering, backups and migration options are advertised. File sharing through webmail should not be treated as the same thing as an independent, full-featured team cloud drive.
• Introductory discounts and a conditional satisfaction guarantee need careful reading. Compare the first invoice with renewal, the term paid in advance, the number of domains and any support limits.

Our view: Worth comparing for Australian hosted email with many mailboxes. Verify the final plan configuration and ongoing price before moving your domain.

Namecheap Private Email gives a small business custom-domain mailboxes with webmail, calendar and other plan-dependent tools. It can be useful when you want straightforward email without the cost of a broad office subscription.

• The Starter tier is the entry point, while higher tiers change mailbox and file allowances. Check the exact number of mailboxes included and whether extra addresses, domains or storage cost more.
• Its trial lets you test the service before paying. Set up your domain records carefully and try the web and mobile experience with real staff accounts before migrating important historical messages.
• Pricing can be shown in US dollars and introductory terms may differ from renewals. Review sending limits and feature restrictions if you send larger volumes of customer correspondence.

Our view: A useful low-cost email comparison, especially for a small team. Measure the total for all mailboxes rather than one advertised entry rate.

Hostinger Email provides custom-domain business mailboxes aimed at small firms that need a branded address and a simple setup. It can be considered alongside a Hostinger website, although the email service can be assessed separately.

• Business Starter is the entry product in this table. Check mailbox storage, supported apps, aliases and any administration features against the higher email editions before selecting a term.
• This is an email solution rather than a shared file workspace. A company that needs collaborative documents or substantial team storage should plan for a separate cloud product or a broader suite.
• Hostinger frequently displays promotional prices and longer prepaid periods. Confirm the renewal rate, currency, taxes, mailbox quantity and sending limits at the Australian checkout; test any available trial offer.

Our view: A practical price-led email candidate. Compare the full term and renewal cost, particularly if you also buy a domain or website plan.
