Fastmail
Fastmail is a privacy-focused email host based in Australia with fast IMAP access and custom domain support for individuals and teams.
What is Fastmail?
Fastmail is one of the oldest independent email providers still operating today, founded in Melbourne in 1999 when most people were still signing up for Hotmail. It built its reputation on a simple premise: email as a paid service, with no advertising, no data mining, and no surveillance of message content. That positioning attracted privacy-conscious professionals, developers, and anyone who had grown tired of Google and Microsoft treating email as a product rather than a service. Fastmail also has genuine technical depth — it is a core contributor to the JMAP standard, a modern replacement for IMAP that offers faster synchronisation and a more reliable protocol for mail clients.
The service runs on infrastructure spread across data centres in the United States and the Netherlands, with a proprietary mail storage engine that was rebuilt from scratch to handle JMAP natively. Fastmail is not just an email provider — it supports custom domain email, contacts, and calendaring, making it a complete communications suite for individuals and small businesses. The company also developed Cyrus IMAP, the open-source mail server used by many large institutions, which reflects the depth of its engineering investment in the email stack.
Email failures on Fastmail tend to be specific rather than total. IMAP or JMAP sync failures prevent mail clients like Apple Mail, Thunderbird, or Mimestream from updating inboxes, even when webmail continues working. SMTP delivery failures cause outgoing messages to queue or bounce. Two-factor authentication problems during login can lock users out entirely. Because many Fastmail users route custom domain mail through the service, outages can prevent email delivery for professional domains, which is significantly more disruptive than a personal mailbox going quiet.
Outage.gg monitors Fastmail service status with real-time community reports. If webmail is unreachable, IMAP sync has stalled, or outgoing mail is failing, the live status page will show whether it is a platform-wide issue.
