What is Fastmail?
Fastmail is an independent email provider that has never offered a free ad-supported tier — every account is a paid subscription, which the company positions as the reason it doesn't need to scan email content for advertising or sell user data. Every plan supports bringing a custom domain, unlimited masked email aliases for signing up to services without exposing a real address, and standards-based protocols (IMAP, CalDAV, CardDAV) so it works with any email client rather than locking users into a proprietary web app. Business plans add per-user pricing with an optional Professional tier that includes a legal-compliance email retention archive. Fastmail runs on infrastructure the company owns rather than a major cloud provider's white-label email product, and offers a 30-day free trial before any plan requires payment.
Fastmail is a subscription email service that runs entirely on paid plans, with no ads and no scanning of email content for advertising purposes. Individual plans start at $6/month ($5/month billed annually, $60/year) for 60GB of combined mail, calendar, and contacts storage, scaling to Duo ($10/month, two private inboxes) and Family (up to 6 users, $14/month); Business plans run per-user from Basic at $4/month per user up to Professional at $10/month per user with legal-compliance email archiving. Every plan includes custom domain support, masked email aliases, and a 30-day free trial, making Fastmail a fit for privacy-conscious individuals and small businesses who want to own their email domain without Google or Microsoft handling it.
Standout feature: Unlimited masked email aliases for signing up to services without exposing a real address, combined with full custom-domain support and standards-based IMAP/CalDAV/CardDAV access on every plan, including the cheapest tier.
Biggest weakness: No free tier at all — every account requires payment after the 30-day trial — and search and spam filtering are generally considered weaker than Gmail's, since Fastmail doesn't have Google-scale machine learning behind its spam engine.
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.
