Fastmail is an independent paid email and productivity service for individuals and businesses, offering fast, private email hosting alongside calendars and contacts. Its apps work across devices and support offline reading, drafting, searching, and management. Users can organize messages with pinned items, powerful search, snoozing, aliases, and Masked Email, while calendar features include event updates and the option to add Google or iCloud calendars. Scheduled sending, VIP notifications, and private message memos help customers manage their time and stay focused.

Fastmail says it does not use customers’ personal data for advertising, share it with third parties, or serve ads. It emphasizes secure, backed-up, and available email, with personal support online 24/7 and no lock-in: customers can move their mail, calendars, and contacts. The service offers a free 30-day trial, business plans, custom-domain email, and migration tools for people switching from providers such as Gmail, Outlook, Yahoo, Proton, or HEY. Fastmail also contributes to open standards, including JMAP, and provides help resources, API documentation, and mobile apps.
