User Reviews

Users broadly praise Fastmail for privacy, a robust feature set (aliases, masked email, custom domains) and a clean, focused experience with strong support. However, the iOS app is frequently criticized for slow loading, lag, and stability issues, plus notification reliability problems. Reviewers want a more modern UI with OS integrations (widgets) and smoother performance. A few mention confusing pricing/paywall behavior. Overall, service quality is solid, but the mobile app’s reliability and polish need improvement.
Pros
  • Privacy-focused and data protection
  • Extensive feature set (aliases, masked email, custom domains, JMAP)
  • Fast, reliable performance and cross-device consistency
  • Strong customer support
  • Simple, clean, focused design with inbox control
Cons
  • App performance issues: slow loading, lag, and stability problems
  • Notification reliability problems (missed, delayed, or incorrect actions)
  • Stability/buggy behavior (hangs, not loading, occasional crashes)
  • Outdated UI and lack of OS integrations (no widgets; limited modern UI polish)
  • Pricing/paywall confusion and plan requirements

Fast, private, and dead simple. No ads or tracking that I can notice just a blazingfast inbox that handles custom domains and aliases flawlessly. Best email switch I’ve made

After using Microsoft 365 and iCloud+, I switched everything to Fastmail for my personal and business domains, and honestly it has been a great experience. The app is extremely fast, clean, and focused without all the extra clutter and upselling. Email, contacts, and calendar sync perfectly between my iPhone and Mac. I also really like that Fastmail feels simple but still very powerful. Push notifications are instant, the interface is clean, and managing custom domains was much easier than expected. A lot of reviews here complain about things that honestly haven’t been an issue for me. If you want a professional, privacy-focused email service that just works reliably, Fastmail is excellent.

This app is overall good, but it launches to a black screen A LOT. I have to kill the app entirely and re-open it for it to load. Please resolve this, it’s pretty frustrating.
