Google Workspace alternatives for small business — the honest take

Google Workspace is the default answer to business email, and for a lot of teams it’s the right one. Gmail is excellent, the deliverability is invisible because it never comes up, and Docs, Meet, Drive, and Calendar are glued together better than any competitor manages. If your whole company runs in Google, stop reading; switching costs will eat any savings.

This guide is for everyone else: the teams paying $7 per person per month (Business Starter, Annual Plan) for a suite they use a slice of, the privacy-conscious, and the spreadsheet-price-shoppers. Here’s what each real alternative actually costs, in money and in hassle.

Where Workspace quietly costs you

• You pay for the suite, not the mail. Email is one part of what $7 a user buys. If your docs live in Notion and your files in Dropbox, you’re paying full freight for a product you use a slice of.
• Month to month costs more. Business Starter is $7 a user a month on the Annual Plan and $8.40 on the Flexible Plan.
• Addresses are capped per person. Each user can have up to 30 aliases at no extra cost. Past that, Google says you need another Google account, which on Workspace is another user to pay for.

The real alternatives, honestly

Every option below trades something away: price, ecosystem, privacy, or your weekends. There is no free lunch; there’s just the lunch that matches your team.

1. Microsoft 365 Business Basic — the default rival

   $7 a user a month for Business Basic, the list price since 1 July 2026 (it was $6), or $5.40 without Teams. If your team lives in Excel and Word, nothing else comes close: the apps are the product and the mail comes with them. Microsoft is also generous with addresses: up to 400 aliases per user at no extra fee, and shared mailboxes need no license up to 50 GB. The trade-off is weight: a big admin center and licensing tiers that take some reading.

2. Zoho Mail — the budget pick

   Free for up to 5 users on one domain (Forever Free, 5 GB each, but without IMAP, POP or ActiveSync), and the paid Mail plans are priced per user and billed annually. Zoho Workplace adds WorkDrive and other apps for teams that want one vendor. For cost-focused teams it’s the rational choice; Zoho prices by region, so check yours on its pricing page.

3. Proton Mail — the privacy pick

   Workspace Standard is $12.99 a user a month billed yearly, with 15 custom domains and 20 addresses per user; Proton also sells mail-only business plans, whose prices we didn’t verify. End-to-end encryption and a Swiss home make it the established privacy option: if that matters to your customers or your regulators, it’s the one. Desktop mail apps connect through Proton’s Bridge add-on. Great at what it optimizes for; it just optimizes for something specific.

4. Fastmail — the email-nerd pick

   Priced per user (Basic, Standard, Professional), with your own domain from the Standard plan up (Basic doesn’t include it). A polished independent host with Masked Email and, in Fastmail’s words, “hundreds of additional email addresses”. What it doesn’t give you is a suite: no docs, no video, no office apps. Teams that already settled their docs and storage question elsewhere and just want good email like it. (Fastmail’s page showed us regional prices, so no dollar figure here.)

5. Self-hosting (Mailcow, Stalwart, docker-mailserver) — the DIY pick

   Technically the cheapest per mailbox and the most control you can buy. It is also a second job: IP reputation warmup and monitoring, SPF/DKIM/DMARC discipline, blocklist disputes, security patching, spam filtering for inbound, and the occasional 3 a.m. page when a queue backs up. The graveyard of small-business email is full of “how hard can it be.” Only choose this if you have someone who genuinely wants to run mail, and see why emails land in spam for the curriculum they’re signing up for.

And then there’s us — SuperMailOS

Full disclosure: this guide is written by an alternative. Here’s the honest framing anyway, because we’d rather be compared than coy.

SuperMailOS is professional email on your own domain with the deliverability setup done for you: SPF, DKIM, and DMARC generated from the mail server’s own zone and checked live (published in one click on supported DNS hosts), every message DKIM-signed, sending on new domains warmed up gradually, DMARC reports parsed into a dashboard, and a threaded webmail inbox that’s simple enough that nobody needs training. It starts at $4 per mailbox per month ($3 billed annually) on Pro, with a $6/$5 Business tier for unlimited domains and 30 GB mailboxes: $3–$4 a mailbox on Pro against $7 a user for Google’s Business Starter or Microsoft’s Business Basic. Full pricing is here, including the 14-day free trial (no card).

What you trade: no office suite, no video conferencing, no drive-and-docs bundle. We do email and only email. If you want the whole workplace in one bill, Microsoft or Google. If you want every domain’s email in one inbox without taking up DNS and deliverability as a hobby, that’s the bet we’re making.

A sensible test before you commit to any of this: run your current domain through the free email checker and read what those records do. Knowing how the plumbing works makes every provider comparison, this one included, easier to judge honestly. Back to all guides.
