$1,680 a year for 20 mailboxes. Or $49.
Microsoft 365 Business Basic · $7 per user per month, paid yearly, USD · 20 mailboxes · checked 9 September 2026
Every address you add is another $84 a year. JustEmails is $49 a year total — unlimited mailboxes, unlimited domains, one inbox.
JustEmails is $49 a year, flat. Microsoft 365 Business Basic is $7 per user per month paid yearly — the same headline rate as Google Workspace Business Starter, so anyone telling you one is meaningfully cheaper than the other is not reading the same pricing page. Twenty mailboxes is $1,680 a year and the rate does not fall with scale. You are buying Teams, Office on the web and 1 TB of OneDrive per user alongside the mailbox, which is good value if your company runs on those and pure overhead if it does not. We do not ship compliance tooling, Teams, or Office, and we will not pretend otherwise. What we do is unlimited mailboxes and domains on one bill, one inbox across all of them, and DNS that configures and monitors itself.

Who should pick what
Who this is for
You are running addresses across many domains and are paying per-seat for mailboxes that are really just routing — the support@, the billing@, the one on a brand you launched last year.
Deliverability: a tie on authentication, decided elsewhere
Microsoft and JustEmails both authenticate correctly — SPF, DKIM and DMARC on every domain — so neither has a structural advantage in the headers a receiving server checks first. Claims of a large deliverability gap between two correctly configured hosts are usually a sales argument rather than a technical one.
What does move inbox placement is sending behaviour: consistent volume, recipients who engage, few complaints, and DNS that is still correct on the day you send. A cold domain sending a sudden spike gets filtered no matter whose infrastructure it leaves from.
Microsoft runs its own reputation programme through SNDS for senders operating their own IPs, which is useful if you are running infrastructure at that level. For a business sending normal volumes of human email, it is not a factor in the decision.
The practical difference is monitoring. The usual cause of a domain quietly falling out of the inbox is not spam complaints but a DNS record that stopped resolving after an unrelated change. We re-check MX, SPF, DKIM, DMARC and MTA-STS every six hours on every verified domain and alert you the first time one breaks. Microsoft will not tell you that.
The bundle you are paying for either way
Business Basic is priced per person at the same headline rate as Google Workspace Business Starter, so the choice between the two big suites is about what each bundles rather than about price. Both charge you the same for a mailbox; they differ in what arrives alongside it.
The comparison worth running is not Microsoft against Google but bundle against no bundle. If Teams, Office and OneDrive are load-bearing for your company, you are buying three products and email is close to free. If they are not, you are buying one product at three products’ price.
That is a question only you can answer, and it is answerable from your own usage data rather than from a comparison page. Check how many of your seats opened Teams last month. The answer tends to settle the argument faster than any table we could put here.
Role mailboxes and the seat model
Microsoft does offer shared mailboxes without a licence, which is a genuine mitigation and more than some competitors provide — under 50 GB and with no direct sign-in, a shared mailbox costs nothing extra. Any team on Microsoft paying per seat for info@ should at minimum be using that.
The limits show up once a role mailbox needs to behave like a real one: its own sign-in, its own sending identity, mail beyond the shared-mailbox ceiling, or an owner who works from it all day. At that point it becomes a licensed seat at the full rate.
On a flat fee the distinction disappears, because mailboxes are not a billable unit at all. Ten role accounts and ten human accounts cost exactly what one costs. Whether that is worth switching for depends entirely on how many mailboxes you are carrying and how much of the suite you use — which the calculator above works out from your own numbers rather than ours.
What a mail-only stack removes
Business Basic bundles Teams, Office on the web and 1 TB of OneDrive per user with the mailbox. If your company runs on those, the per-seat price is not really an email price and comparing it to ours is comparing two different purchases.
The case for separating them is narrower and worth stating precisely. Role mailboxes — support@, billing@, careers@, per-client addresses — need to receive, send, authenticate and be searchable. They do not need OneDrive, and on a per-seat plan they are billed as though they do.
Splitting rather than switching is what most teams land on: keep Microsoft seats for the people who genuinely use Office and Teams, and move the function mailboxes to a flat fee. That is not a compromise position, it is usually the correct one, and it is how we run our own company.
What the flat side gives you beyond price: unlimited domains rather than per-domain configuration, one inbox spanning all of them, DNS generated and verified per domain with six-hourly re-checks and drift alerts, and 140+ MCP tools so Claude or ChatGPT can operate the mailbox directly. What it does not give you is compliance tooling, eDiscovery or litigation hold — if an auditor expects those, Microsoft's higher tiers are the answer and we do not ship them at all.
Common questions
Is Microsoft 365 cheaper than Google Workspace?
No — Business Basic and Business Starter are both $7 per user per month. Any comparison implying a price gap between them is wrong. The difference is what each bundles, not what each costs.
Is JustEmails cheaper than Microsoft 365?
From the first mailbox, on price alone. Twenty mailboxes is $1,680 a year on Business Basic against our flat $49. But you lose Teams, Office and OneDrive, which for many teams is the actual reason they pay.
Do I lose Teams if I move email?
Yes, if you drop the Microsoft subscription entirely. Some teams keep a small number of Microsoft seats for Teams and Office and move the routing-only mailboxes to us — that is a reasonable split.
Can I migrate from Microsoft 365?
Yes. Our migration tool connects to Microsoft accounts and copies mail with folder structure preserved, running in parallel with your existing tenant.
Can I keep using Outlook?
Yes — Outlook speaks IMAP and SMTP, so it connects to a JustEmails mailbox like any other client. What you lose is the Exchange-native layer: automatic shared-mailbox sync and calendar delegation. Mail, folders and sending all work normally.
What about compliance — eDiscovery, litigation hold, DLP?
Microsoft has them at the higher tiers and we do not ship compliance tooling at all. If an auditor expects those controls, stay on Microsoft. That is not a close call and we would rather say so than sell you something that fails an audit.
How do shared mailboxes migrate?
They need a decision rather than a straight copy. A Microsoft shared mailbox becomes either a normal JustEmails mailbox or an alias with routing rules, depending on whether anyone needs to send as that address. Either way it stops being a licensing question, because mailboxes are not billed individually here.
