Fastmail vs Google Workspace pricing: which costs less?

Fastmail costs less per user for email alone, starting at $4/user/month versus Google Workspace's $7/user/month, but Google Workspace bundles a full office suite that Fastmail doesn't include at any price.

Fastmail's Business Basic tier ($4/user/month annual) covers 6GB of mail, contacts, and calendar storage. Google Workspace's Business Starter ($7/user/month annual, $8.40 billed flexibly) adds 30GB of pooled storage plus Docs, Sheets, Slides, and Meet for up to 100 participants. For teams that only need email, Fastmail is cheaper; for teams that would otherwise buy office software separately, Workspace's bundle can be the better value.

Which has more storage, Fastmail or Google Workspace?

Google Workspace offers more storage at comparable and higher tiers, scaling to 2TB and 5TB pooled per user, while Fastmail's top Business Professional tier caps at 150GB per user.

Which is better for team collaboration, Fastmail or Google Workspace?

Google Workspace is built for collaboration, with real-time multi-user editing across Docs, Sheets, and Slides plus Meet video calls in the same subscription, while Fastmail focuses on email, calendar, and contacts alone.

Fastmail's Business Standard and Professional tiers add Scheduled Send, Snooze, and a legal-compliance archive, but no document editing or video conferencing. Google Workspace layers Gemini AI writing assistance across Docs, Gmail, and Meet at increasing depth by tier, aimed at teams standardizing on browser-based collaboration rather than desktop office software.

Can Fastmail replace Google Workspace?

Only for the email component; Fastmail has no equivalent to Google's Docs, Sheets, Slides, or Meet, so teams relying on those would need a separate office suite alongside Fastmail.

Fastmail matches or beats Workspace on custom-domain email pricing, masked aliases, and standards-based client access. Teams that need real-time collaborative documents or bundled video conferencing under the same subscription should stay with Google Workspace or pair Fastmail with a separate office tool.

Strengths and weaknesses

Fastmail

Pros

No ads and no scanning of email content for advertising, unlike free webmail providers.
Custom domain support and unlimited masked email aliases included on every plan, even the cheapest.
Standards-based IMAP/CalDAV/CardDAV access works with any email client, avoiding vendor lock-in.
Business Professional tier includes a legal-compliance email retention archive.

Cons

No free tier; every plan requires payment after the 30-day trial ends.
Spam filtering and search are generally weaker than Gmail's machine-learning-driven systems.
No AI-assisted writing or summarization features that Gmail and Outlook now offer.
Base Individual plan's 60GB storage is smaller than Gmail's free 15GB-plus-cheap-upgrade model once photos and attachments accumulate.

Google Workspace

Pros

Real-time collaborative editing across Docs, Sheets, and Slides with automatic saving.
Gemini AI features are bundled into every paid tier rather than sold as a separate add-on.
Tight integration across Gmail, Drive, Calendar, and Meet under one admin console.
Transparent, published per-user pricing with no mandatory onboarding fee.

Cons

Offline and power-user editing features lag behind Microsoft 365's desktop Excel and Word.
No official native Linux desktop client for Drive sync.
Google Meet participant caps and storage limits are hard-capped per tier, forcing plan upgrades.
Lowest advertised per-user price requires annual billing; flexible monthly billing costs about 20% more.

Which fits your use case?

Privacy-conscious business that wants no ads or content scanning on its email	Fastmail	Fastmail runs on paid subscriptions with no ads or content scanning on any tier, a core design principle of the product.
Organization wanting AI-assisted drafting and summarization across email and documents	Google Workspace	Google Workspace bundles Gemini AI features into every paid tier; Fastmail has no AI writing assistance.
Team needing large pooled storage for shared files alongside email	Google Workspace	Google Workspace scales to 5TB pooled storage per user on Business Plus, far beyond Fastmail's 150GB top-tier cap.

Neither a match?

Both lists carry verified pricing and honest weaknesses for every option.
