Bottom Line
Six dollars. That is the number three of the four major business email platforms have quietly converged on, and it is the single most misleading figure in this entire category. As of September 22, 2026, Microsoft 365 Business Basic starts at $6/user/month and Google Workspace Business Starter was priced at $6/user/month with 30GB of storage per user as of early 2025 — identical sticker, wildly different products underneath. The price is not the decision. The storage runway and the migration pain are.
According to Google News, ZDNET published an updated expert-tested roundup of the best email hosting services for small businesses, covering the same core field: Microsoft 365, Google Workspace, Zoho Mail, and privacy-first options such as Proton Mail. What follows is not a restatement of that roundup. It is the arithmetic underneath it — the part that determines whether you are still happy with your choice in year three.
The Job You're Actually Hiring Email Hosting To Do
Strip away the feature lists and a small business hires business email to do exactly three things: make you look legitimate at the domain level (yourname@yourcompany.com instead of a free consumer address), keep mail from disappearing, and not become an IT project. Everything else — the shared calendars, the video calls, the document suite — is a bundle that vendors attached to that job because bundling is how you defend a $6 price point.
That framing matters because it reveals who the real competitor is. It is not Zoho versus Google. It is "professional email hosting" versus "the free mailbox that came with my web hosting plan," which is where a surprising number of very small businesses still sit. Email hosting and web hosting are different products: web hosting stores the files that make your site load, email hosting runs the mail servers, spam filtering, and deliverability reputation that decide whether your invoice lands in an inbox or a junk folder. The bundled mailbox from a shared web host technically works. It also typically ships with a few gigabytes of storage, no meaningful admin console, and shared-IP sending reputation you do not control.
The market has already voted on that question. Over 60% of small businesses with professional email use either Microsoft 365 or Google Workspace, and Microsoft 365 holds approximately 48% of the productivity software market share for businesses under 100 employees. Industry context explains the consolidation: the category reorganized itself around cloud productivity suites that bundle storage, calendaring, and collaboration, and the 2020–2024 shift to remote work made integrated communication platforms close to mandatory rather than optional.

Run the Storage Math Before You Run the Price Comparison
Here is the non-obvious part, and it is where the surface reporting on this category consistently stops short. Reviewers compare entry tiers on price. Entry tiers do not fail on price. They fail on storage, and they fail on a schedule you can calculate in advance.
Average small business email storage requirement runs 15–20GB per user annually based on 2024 usage patterns. Google Workspace Business Starter was priced at $6/user/month with 30GB per user as of early 2025. Divide the two: at the 15GB/year end, a Starter mailbox has roughly a two-year runway. At 20GB/year, it is closer to 18 months. Meanwhile, industry experts typically recommend 25–50GB minimum per user for small business email hosting — meaning the 30GB entry tier sits at the very bottom of the recommended band on day one, before a single attachment lands.
Chart: Entry-tier mailbox storage (30GB, Google Workspace Business Starter, early 2025) against annual small business usage of 15–20GB per user (2024 patterns) and the 25–50GB per-user minimum experts typically recommend.
Now price the upgrade you are probably scheduling for yourself. Microsoft 365 Business Standard runs $12.50/user/month against Business Basic's $6 — a $6.50 monthly delta, or $78 per user per year. For a five-person team that is $390 a year, and for a ten-person team $780. That is the number to hold in your head, because "we'll upgrade later if we need to" is a decision with a price tag, not a deferral.
Against that, Zoho Mail's paid plans start at $1/user/month for small businesses, with a free tier covering up to five users. Compare it directly: Zoho at $1 versus Microsoft 365 Business Basic at $6 is a $5/user/month gap — $60 per user per year, $600 annually for a ten-person team. The honest question is not which is cheaper. It is what that $600 buys. On the Microsoft side it buys the bundled productivity suite, the admin tooling, and the ecosystem gravity implied by that 48% share among sub-100-employee businesses. On the Zoho side it buys you $600 back and a mail platform that does the core job competently.
A careful skeptic should push back here, and the pushback is fair: cheap email is only cheap if your team is not already living inside Excel and Teams, or inside Docs and Meet. If your workflow automation and team collaboration already run through one of the big two suites, the $1 mailbox is not a $5 saving — it is a $5 saving plus a second toolchain to maintain. That is a productivity software tax that rarely shows up on the comparison table.
Where AI Changed the Comparison — and Where It Didn't
Microsoft announced AI Copilot integration across Microsoft 365 business tiers throughout 2024–2025, and Google introduced Gemini AI assistant features to Workspace business plans in late 2024. Both embed assistants that draft messages, summarize threads, and automate administrative work, which repositions email hosting as one component of a broader AI productivity ecosystem rather than a standalone mail service.
Our read: the AI layer is a real differentiator at the top of the stack and close to irrelevant at the bottom of it. If you are buying the $6 entry tier to get professional addresses on your domain, the assistant is not what you are paying for. The demo is not the product. But the strategic consequence is worth naming — once AI assistants are trained on your mail archive and calendar, the bundle stops being a convenience and becomes the lock-in, which is a pattern AI Agents Lab traced in enterprise agent adoption forecasts.
Which Fits Your Situation — and What Switching Actually Costs
The data export reality is the part nobody prices at signup. Mailbox contents are portable; IMAP migration tools move messages between nearly all of these providers. What is not portable: your calendar invites and their attendee links, your shared drive permissions, your distribution lists and aliases, third-party apps authenticated against your identity provider, and — the expensive one — the muscle memory of every person on your team. The moment you outgrow a platform is rarely the moment you leave it, because leaving costs days of low-grade chaos that no spreadsheet captures.
Take your current mailbox size, divide by the years you have had it, and compare the annual figure against the 15–20GB/user benchmark. If you are at the high end, a 30GB entry tier buys you roughly 18 months. Budget the upgrade now — for Microsoft that is the $6.50/user/month step from Business Basic to Business Standard, or $78/user/year.
If your contracts, spreadsheets, and client deliverables already live in one ecosystem, buy email from that ecosystem. The two leaders are the top choices for teams prioritizing collaboration precisely because of the integrated suites, not the mail server. If your documents are genuinely platform-agnostic, Zoho's $1/user/month tier — or its free plan for up to five users — is the rational default, and you keep the difference.
Proton Mail's business plans start around $6.99/user/month with end-to-end encryption (only sender and recipient can read the message — the provider cannot). Privacy-focused businesses are increasingly weighing Proton and Tutanota despite higher costs, a shift tied to GDPR and emerging US state privacy laws that raised demand for encrypted mail across 2023–2025. If you handle health, legal, or financial client data, that $0.99 premium over the $6 tier is a compliance line item, not a splurge.
The verdict, with conditions attached. Adopt Microsoft 365 if your team already works in Office files and you want the largest ecosystem — the sub-100-employee market share says you will not be an outlier. Adopt Google Workspace if your team is browser-native and collaborative editing is the daily habit, but plan the storage upgrade into year two rather than discovering it. Adopt Zoho Mail if email is genuinely the only job and you would rather keep the $600 a year. Adopt Proton if encryption is a client requirement. Wait — meaning stay on your current bundled host — only if you are a solo operator with a domain address already working and no team to coordinate.
On balance, our analysis is that the entry-tier convergence at $6 is a floor that holds, and the real competitive action over the next few years moves to storage allowances and AI assistant quality rather than headline price. The team-size cliff is where these decisions get expensive: the platform that is obviously right at three people is frequently the wrong one at fifteen, and the migration bill arrives precisely when you have the least time to pay it.
Frequently Asked Questions
How much does business email hosting actually cost per user in 2026?
Entry tiers cluster tightly. As of September 22, 2026, Microsoft 365 Business Basic starts at $6/user/month and Business Standard at $12.50/user/month (pricing as of early 2025); Google Workspace Business Starter was $6/user/month with 30GB per user in early 2025; Zoho Mail paid plans start at $1/user/month with a free tier for up to five users; and Proton Mail business plans start around $6.99/user/month. Verify current pricing directly with each vendor before budgeting.
Is Google Workspace or Microsoft 365 better for a small business?
Neither wins universally — it depends on where your existing documents live. Microsoft 365 holds approximately 48% of productivity software market share among businesses under 100 employees and is the stronger fit for teams working in Office file formats. Google Workspace suits browser-native teams that collaborate in real time. Both are entry-priced at $6/user/month, so the tiebreaker is workflow, not cost.
Do I really need professional email hosting for a small business?
If you send invoices, quotes, or client proposals, yes. A domain-based address affects both credibility and deliverability, and dedicated email hosting gives you spam filtering, admin controls, and a sending reputation that a bundled web-host mailbox generally does not. Over 60% of small businesses with professional email already use Microsoft 365 or Google Workspace.
What is the difference between email hosting and web hosting?
Web hosting stores and serves the files that make your website load. Email hosting runs the mail servers, spam filtering, storage, and deliverability infrastructure for your domain's addresses. Many web hosting plans include basic mailboxes, but those typically come with far less storage than the 25–50GB per user experts typically recommend for small business use.
