Fastmail is an email service offering paid email accounts for individuals and organizations. It is provided in 36 languages to customers worldwide by Fastmail Pty Ltd, a company located in Melbourne, Victoria, Australia.
The company was acquired by Opera Software in 2010. On 26 September 2013, Fastmail announced that it had split from Opera and became a privately held independent company. Its main servers are located in New York City and Amsterdam; a previous backup location in Iceland is being replaced[when?] by the server location in Amsterdam.
Fastmail was founded in 1999 by Rob Mueller, Bruce Davey, and Jeremy Howard, to provide email service for customers of the Optimal Decisions Group.
The provider's sole product line is email services (and included accessories), but it was owned by Opera Software (best known for its web browser) from 2010 to 2013. Through a staff buyout, the company became fully independent again.
On 18 October 2012 Fastmail announced that new signups for the free service level had been discontinued. Existing free Fastmail accounts would not be discontinued, but if a free account was deactivated because it was not logged into in over 120 days, it would not be reactivated. The company stated that they had decided to focus Fastmail as a "premium brand" with only paid accounts.
When first established, the service was intended to differentiate itself through providing features that were not yet available from other market players. Early on, this included the ease and speed of email transport and access, personalities and IMAP and SSL support, and an independent public forum and wiki among user support options. Over the years, these features became commonplace, but features such as WebDAV, secure LDAP, opportunistic inter-server encryption, reliability via minimization of single points of failure, and customizable filtering via Sieve are current differentiators.
On October 23, 2014, Fastmail moved their primary domain from
All existing "guest" and "one-time payment" member email accounts were discontinued on July 31, 2017 as Fastmail transitioned into a subscription-only email service. Existing users were given the option to subscribe to Fastmail with a discount or to request a refund of their one-time payment. 
As of December 2018, Fastmail and all other Australian companies are subject to the Assistance and Access Bill, which compels them to assist law enforcement in accessing encrypted communications if warranted during an investigation. Fastmail stated that while their services were not "materially affected" since they already complied with warrants per the Telecommunications Act, concerns have been shown by customers over the bill's effects.
On June 24th, 2019, Fastmail launched refreshed look, with a new logo, app icon, colors, and website. The logo now reads "Fastmail" instead of "FastMail".

Fastmail offers 113 domains which users can choose from, while also allowing customers to use their own domain. Users are also able to create calendars and notes in the web mail environment and sync them over the IMAP and CalDav protocol.
The site developers are among active contributors to the widely used Cyrus IMAP open source software project and include the lead developer and maintainer of Perl module Mail::IMAPTalk. They are actively developing JMAP - a new open email protocol.
Fastmail also provides for two-factor login using a YubiKey. While associating one or more YubiKeys with a Fastmail account will not prevent normal logins, it allowed for logging on to an email account with just a YubiKey and its auto-generated one time passwords, making it suitable for accessing email on public machines. The YubiKey-only login feature was discontinued in July 2016, as it was rarely used, according to the Fastmail team.
