What Fastmail is
Fastmail is an Australian-run email host, independently owned, with a 25-year track record. It is not a surveillance company that also offers email. It does not read your email to serve ads. It does not have a free tier designed to lock you in before raising prices.
For teams who want to get off Google’s data model without going full-Proton (end-to-end encryption, learning curve, iOS app friction), Fastmail is the obvious middle ground.
Deliverability: 79% IPR
In our Q1 2026 test, Fastmail landed 79% of messages in the primary inbox — below Google (87%) and Microsoft (82%), but above Zoho (71%) and well above the budget hosts. For teams that are not running active cold outreach, 79% is acceptable.
Pricing: clear and stable
Fastmail Standard costs $5.00/seat/month, with no introductory pricing and no planned increases we are aware of. The STABLE badge applies.
| Tier | Price/seat/mo | Storage | Key feature |
|---|---|---|---|
| Basic | $3.00 | 2 GB | Personal use |
| Standard | $5.00 | 30 GB | Business, custom domain |
| Professional | $9.00 | 100 GB | Masked email, priority support |
The Standard tier is the correct business tier. Basic’s 2GB storage makes it impractical for professional use.
Where Fastmail wins
Clean webmail. The Fastmail webmail interface is noticeably better than Zoho’s — faster, less cluttered, and with a well-implemented calendar. For teams that live in webmail rather than desktop clients, this matters daily.
Privacy model. Fastmail is GDPR compliant, has a straightforward privacy policy, and does not monetise your email data. For teams with EU clients who ask “where is your email hosted?”, the Fastmail answer (“Australian company, data in EU datacentres, no ad targeting”) is cleaner than Google’s.
Multi-domain support. Standard tier supports custom domains. Up to 600 aliases per account. For small agencies with 2-4 brands, this is workable.
Migration tooling. Fastmail’s IMAP import tool handles Gmail, Microsoft 365, and most other providers cleanly. Average import time for a 5-seat team: 2-3 hours.
Where Fastmail falls short
No BAA. Fastmail explicitly does not sign HIPAA Business Associate Agreements. If you are a medical practice, therapy service, or any healthcare entity, Fastmail is not an option — full stop.
No calendar sharing with external users. Fastmail’s calendar is solid for internal scheduling. External calendar sharing (sharing a calendar link with a client) is functional but less polished than Google Calendar.
Thinner admin tooling. Managing 20+ users in Fastmail is more manual than Google Workspace or Microsoft 365. Provisioning, deprovisioning, and enforcing security policies requires more hands-on work.
No desktop apps. Fastmail is webmail and IMAP. If you need desktop Office integration, this is not the product.
Who Fastmail is for
The ideal Fastmail buyer is a 1-15 person team that:
- Does not need HIPAA/BAA compliance
- Wants a clean email experience without Google’s data model
- Does not need deep Salesforce, Slack, or HubSpot integrations
- Is willing to pay $5/seat vs $0 (Zoho Free) for meaningfully better webmail quality and privacy
If all of those are true, Fastmail is the right answer.
Verdict
Fastmail occupies a specific and defensible niche: clean, fast, privacy-respecting business email at $5/seat/mo. It is not trying to be Google Workspace. It does not have Google’s integrations, admin tooling, or BAA availability. What it has is a genuinely good product with 25 years of reliability and a clear business model.
Score: 7.9/10. Deducted for no BAA and lighter admin tooling. High marks for webmail quality, privacy model, and price stability.
