Fastmail is a private email and calendar hosting platform that manages online communications, schedules, and contact lists.
Fastmail is an independent email, calendar, and contacts hosting service operated by Fastmail Pty. Ltd., which is headquartered in Melbourne, Australia, with an additional satellite office in Philadelphia, USA. Operating since 1999, the provider offers web-based and application-driven email solutions for individual users, side projects, and business organizations. The company runs on a paid subscription business model, meaning customer data is not mined, used for targeted advertising, or sold to third-party marketing entities.
The platform provides an environment for managing daily communications, schedule tracking, and contact address books. Users can access their accounts through web browsers or native applications on mobile devices running iOS or Android. The web interface and mobile software support both online use and offline functionality, allowing account holders to search, read, draft, and organize messages, calendar entries, and address books without a continuous internet connection.
Fastmail incorporates a variety of workflow capabilities to assist with message management and inbox organization. Users can pin high-priority messages to the top of their message list, snooze incoming items such as bills or event tickets until a future date, and attach private memos directly to email threads. Additional tools include scheduled sending, undo send functionality, VIP notification filters, and conversation muting to keep unwanted reply chains out of the main inbox.
Data privacy and account security are fundamental components of the infrastructure. Fastmail encrypts customer data both in transit and at rest within locked server racks in secure data centers. Subscribers can choose their primary data residency location in either the European Union or the United States. Account protection options include traditional passwords, two-step verification, and passwordless passkey login. To guard against web tracking, the system automatically blocks spy tracking pixels in HTML mail and offers Masked Email addresses.
Fastmail focuses on open internet standards and system interoperability. The provider actively participates in industry standards bodies such as the Internet Engineering Task Force (IETF), M3AAWG, and CalConnect. It maintains open-source software projects including the Cyrus mail server, the Squire rich text editor, and the Overture JS framework, and developed JMAP (JSON Meta Application Protocol) to modernize open email and calendar synchronization across different software platforms.
Businesses and individuals can host email addresses under their personal or company domain names rather than generic provider domains. Accounts support up to 100 custom domains without extra fees. Setup can be completed by connecting an existing registrar or purchasing new domains directly through the interface after seven days of active paid subscription. Catch-all aliases can also be configured to collect messages sent to unassigned domain addresses.
Users moving from third-party services such as Gmail, Outlook, Yahoo, Proton, or HEY can transfer their existing communications into Fastmail. The service includes dedicated migration tools designed to copy over messages, contact lists, and calendar schedules. Because the platform relies on standard protocols like IMAP, CardDAV, and CalDAV, incoming data from standard formats can be imported quickly without platform lock-in.
Individuals looking to keep their real email address private from online tracking can generate Masked Email addresses for web registrations. This prevents web advertisers from using a single email address as a persistent cross-site tracking identifier. Additionally, Fastmail automatically neutralizes hidden spy tracking pixels inside HTML emails, preventing senders from monitoring when messages are opened or identifying the recipient's physical location.
Professionals who need to maintain email and scheduling workflows without constant internet connectivity can use Fastmail's offline capabilities. Users can search through archived messages, draft new email replies, manage contact entries, and update calendar appointments while disconnected. Once connected back to the internet, all offline changes, drafts, and scheduled sends automatically synchronize with the mail servers across connected applications.
Users who maintain multiple calendars across different ecosystems can consolidate their schedules within Fastmail by linking external Google or iCloud calendars. The integrated calendar updates when event changes occur and connects directly with an address book that surfaces recent email exchanges and upcoming meetings. This enables individuals to monitor personal and work schedules in one view alongside their inbox.
Users seeking better inbox organization can utilize features such as pinning, snoozing, and thread muting. Important emails can be pinned to the top of the message list so they remain visible. Messages containing event tickets or upcoming bills can be snoozed to reappear at specified dates, while noisy group reply chains can be muted to route future responses away from the inbox.

Until real users review Fastmail, this tab shows what the vendor highlights and the points worth checking — never invented opinions.
Masked Email enables users to create unique, randomly generated email addresses for online sign-ups and app registrations. This functionality keeps the user's primary email address hidden, preventing online advertisers and tracking scripts from using a single static email address to follow user activity across various websites.
Fastmail permits users to link custom domain names to their account or buy new domains directly through the settings interface after seven days of paid membership. A single account supports up to 100 custom domains without added cost, offering catch-all address routing and domain user management.
Subscribers can select their primary data residency location during account setup, choosing between data center infrastructure located in the European Union or the United States. In both regions, data is encrypted on physical disks located inside locked server racks in secure data facilities.
Users can defer incoming messages such as tickets, reminders, or bills by snoozing them so they reappear in the primary inbox at a chosen future date. Similarly, scheduled send allows users to write email messages ahead of time and specify the exact time they should be sent.
Important messages can be pinned directly to the top of the inbox to ensure constant visibility above newer incoming mail. In addition, users can attach private notes or memos to message threads to record reminders, context, or payment details without modifying the original email text.
Fastmail offers multi-factor authentication options to secure account access against unauthorized logins. Account holders can configure standard two-step verification or implement passkeys for passwordless login, providing phishing-proof authentication across modern web browsers and compatible hardware.
The platform includes multi-level undo functionality across its web interface, including message composition. If a user accidentally sends an email with missing information or incorrect recipients, the undo send function allows them to stop delivery and revert the action immediately after sending.
To protect user privacy and prevent location monitoring, Fastmail automatically disables embedded spy tracking pixels inside HTML messages. This security mechanism prevents external senders and marketers from detecting when an email is opened, how many times it was viewed, or the recipient's geographic position.
Fastmail combines email hosting with a built-in calendar and contact address book. The calendar allows users to consolidate schedules by linking external Google or iCloud calendars, while the contact directory automatically highlights recent email conversations and upcoming meetings linked to individual entries.
When a user no longer wants to follow an ongoing email thread, they can apply the conversation muting control. Once muted, future replies to that specific thread bypass the primary inbox and are archived automatically without triggering unread message notifications.
The Fastmail web application and native mobile clients include full offline capabilities. Users can search through archived emails, compose new drafts, update address book contact information, and edit calendar entries without an active internet connection, with changes synchronizing automatically upon reconnecting.
Built around open standards, Fastmail supports traditional email protocols including IMAP, CardDAV, and CalDAV. It also utilizes JMAP (JSON Meta Application Protocol), an open sync protocol co-developed by Fastmail to provide faster data transfer, improved API access, and efficient offline app synchronization.
