Google Workspace is the default choice for a reason. It’s built on Gmail, so there’s no learning curve for you or your clients, and comes with the full suite of Docs, Sheets, Slides, Drive, and Meet with every plan. For a freelancer replacing a Gmail.com address, or a remote team that needs shared calendars and video calls without buying a separate tool, that bundling saves real money.

Business Starter runs $7 per user monthly on an annual plan, with 30GB of pooled storage, custom business email, and Gemini AI in Gmail. Business Standard steps up to $14 per user monthly with 2TB of storage and Gemini across every app including Docs, Sheets, and Meet. I found Standard is where most small teams land, since Starter’s 30GB fills up fast once you’re storing client files alongside email.

The setup process took me under 15 minutes from signup to sending my first email from a custom domain, using Google’s guided DNS verification. Where it gets frustrating is cost creep: Every team member needs a full paid seat, there’s no discounted option for shared inboxes like info@ or support@, and Google has raised prices twice in the past two years to fold in AI features you may not use.

Still, if your business already runs on Google tools, or you want your email hosting to double as your document and video conferencing platform, nothing else on this list matches the breadth. Freelancers who only want email and nothing else should keep reading, because you’ll likely pay less elsewhere.

Google Workspace features: Custom business email | Gemini AI assistant | Google Meet video calls | 30GB to 5TB pooled storage | Docs, Sheets, Slides | Google Drive | 24/7 support

Proton Mail built its reputation on privacy, and that hasn’t changed with its 2026 business tiers. The company is based in Switzerland with strict data protection laws behind it. This means every email is encrypted end-to-end by default and Proton doesn’t scan your inbox to serve you ads or train AI models. For freelancers handling sensitive client data like legal, healthcare, or financial work, that’s a genuine differentiator rather than marketing spin.

Mail Essentials starts around $7 per user monthly on an annual plan and covers custom domains, calendar sharing, and SMTP access for connecting outside tools. Workspace Standard, priced at around $13 per user monthly, adds 1TB of storage plus Proton’s full productivity suite: Drive, Docs, Sheets, and video meetings for up to 50 participants. Workspace Premium pushes past $19 per user monthly and unlocks 3TB of storage and the Lumo AI writing assistant.

Also: Proton just launched a Google Workspace alternative – and it’s fully encrypted

I ran into the platform’s most-cited limitation almost immediately: Proton doesn’t support standard IMAP or SMTP the way Gmail does, so using it inside Outlook or Apple Mail means installing Proton’s Bridge app, which is only available on paid plans. That’s a dealbreaker for teams who live in a specific email client and don’t want another background process running.

For a solo freelancer who mostly stays inside Proton’s own apps, though, the encryption and privacy tools genuinely deliver, and migrating from Google Workspace is handled through Proton’s own Easy Switch tool. Note that pricing pages didn’t fully render exact current figures during my research, so double-check Proton’s official business plans page before you commit a team to a paid tier.

Microsoft 365 is the safer bet for freelancers and small teams that already work in Word and Excel, or that regularly exchange files with clients who do. Business Basic costs $7 per user monthly on an annual plan and includes web and mobile Office apps, Outlook email on your own domain, and Teams. Business Standard runs $14 per user monthly and adds the full desktop versions of Word, Excel, and PowerPoint. This matters if you’re formatting long documents or complex spreadsheets rather than just viewing them.

Business Premium holds steady at $22 per user monthly and layers on Microsoft Defender for Business, device management through Intune, and stronger identity controls. Microsoft held this tier’s price flat during its July 2026 pricing update even as Basic and Standard both rose. This suggests it wants to nudge security-conscious small businesses toward Premium.

I found Outlook’s interface less immediately intuitive than Gmail for anyone coming from a personal Gmail account, though it’s second nature if you’ve used Office in a past job. The desktop apps are still the gold standard for anyone doing heavy spreadsheet work or long-form document editing, which Google’s web-based equivalents don’t fully match.

Copilot AI is a separate add-on rather than bundled in, unlike Gemini in Google Workspace, so if AI assistance is a priority for your team, factor that extra cost into your comparison. For freelancers who bill clients using detailed Excel models or collaborate with corporate clients who live in Office file formats, Microsoft 365 remains the more compatible choice.

Fastmail skips the productivity-suite bundling entirely and focuses on doing email well, which is exactly what a lot of freelancers actually want. There’s no Docs, no Drive, no video calling tacked on, just fast, ad-free email with real human support behind it. For a one-person business that already uses separate tools for documents and calls, paying for features you’ll never touch inside Google Workspace or Microsoft 365 stops making sense.

Business Basic starts at $4 per user monthly and covers shared team addresses like support@yourbusiness.com, though it skips custom domains and third-party email client support. Business Standard, Fastmail’s most popular business tier, runs $6 per user monthly and unlocks custom domains, Scheduled Send, and compatibility with Outlook, Apple Mail, and other IMAP clients. Business Professional climbs to $10 per user monthly and adds an email retention archive built for legal and compliance needs.

What stood out during testing was how quickly Fastmail’s interface loads compared to Gmail or Outlook on the web, and how easy it is to mix plan tiers within one account, putting an owner on Professional while contractors sit on cheaper Basic seats. Fastmail is also privately owned and based in Australia, which appeals to freelancers who’d rather not hand their inbox to a Big Tech company.

The tradeoff is real, though: There’s no built-in video conferencing, document editor, or AI assistant, so you’ll need separate tools for anything beyond email, contacts, and calendars. If that’s a fair trade for lower cost and a cleaner inbox, Fastmail is one of the better-value picks on this list.

Fastmail features: Custom business domains | Shared team addresses | Masked Email aliases | JMAP-based sync | Scheduled Send and Snooze | Admin controls | 24/7 human support

Spike takes the most unusual approach on this list, turning your inbox into something that looks and feels like a chat app rather than a stack of formal message threads. For freelancers who find traditional email exhausting, or remote teams that already think in Slack-style conversations, that reformatting genuinely changes how fast you move through a full inbox.

Spike’s free Teamspace plan includes one @spike.team address and 15GB of shared storage, which is enough to test the format before paying anything. The Team plan runs around $4 per user monthly on annual billing and adds a custom domain, free for the first year. The Business plan, priced near $8 per user monthly annually, expands storage to 1TB and adds priority support, while Ultimate tops out near $10 per user monthly for the heaviest users.

During testing, the chat-style layout took a day or two to adjust to, especially for longer client threads where I wanted to see full formatting rather than condensed bubbles. It’s genuinely faster for quick back-and-forth, though, and the built-in video calls meant I didn’t need a separate Zoom or Meet link for quick check-ins.

Spike isn’t the right fit if your business runs on formal, well-formatted correspondence, or if you need deep integrations with tools like Salesforce or HubSpot, since its ecosystem is thinner than Google’s or Microsoft’s. But for a freelancer or small remote team that wants email to feel less like a chore, it’s worth the free trial.

Spike features: Conversational email threads | Custom team domain | Shared inboxes | Built-in video and voice calls | Collaborative notes and tasks | AI email summaries | Priority support (Business tier)
