Overview

Fastmail is a private email hosting service that provides email, calendar, and contacts for individuals and businesses, with a 30-day free trial and no credit card required. It emphasizes privacy and security features such as Masked Email, aliases, encryption in transit and at rest, two-step verification, and passkey support. Users can choose primary data residency in the EU or USA. Fastmail also offers native apps for every platform and tools like scheduled send, snooze, and VIP-only notifications. The company describes itself as a small team and as a leading advocate for open, interoperable email and calendar ecosystems, contributing to standards bodies and open-source projects including the Cyrus server and the JMAP protocol.

History

Fastmail presents itself as a small team making a big impact, valuing self-motivated people looking to push the frontiers of technology to build a better internet. The company states it is the leading advocate keeping the email and calendar ecosystems open and interoperable, fighting against the encroaching proprietary capture of the big tech giants in the field. It is active at the Internet Engineering Taskforce (IETF), M3AAWG, and CalConnect, and leads the design and specification of JMAP — The JSON Meta Application Protocol (RFC8620). Fastmail also contributes heavily to improving legacy protocols like IMAP and building industry-wide anti-abuse measures. As part of building Fastmail, the company creates libraries and foundational software and open-sources much of its work on GitHub. Cyrus, the server that stores email, contacts, and calendars at Fastmail and supports access via JMAP, IMAP, CardDAV & CalDAV, was originally started by Carnegie Mellon university and is now deployed widely around the world, with Fastmail as the primary contributor and maintainer.
