FMail2 runs on macOS 11.3 Big Sur and higher and is notarized by Apple.
The current version is 1.6.2.
Email provider Fastmail has native iOS
and Android clients. But nothing for macOS. The web interface used by Fastmail
The big thing missing, is that the web interface cannot behave like a native mail application. It can, for example, not handle email links. When you click on such a link it is the macOS Mail application that opens. That is not what we want.
When you have installed FMail2 and have
adjusted your default email client, a click
on an email link will open FMail2 with all provided fields filled.
Even if you have closed the FMail2 window, you will receive notifications for new email and the Dock icon count will be updated.
There are a lot of extra options too. Even options not available in Fastmail, such as searching inside an email and quoting the selected text only. Downloading is handled inside the application and the files are saved in your Download folder (or to another folder of your choice). If you use Fastmail in your browser, switch to FMail2 now. For free. Guaranteed no tracking of your data. You won't regret.
FMail2 is an all Swift Mac application, taking little resources on your system and runs natively on Apple Silicon. Checking email is independent of the view chosen, as FMail2 uses JMAP to update this kind of information.
Clicking an email link elsewhere will open the Compose panel, with all provided fields filled (if you have made FMail2 your default email client)
FMail2 will offer to be the default email program
Define a shortcut key to show/hide FMail2
Reply an email with only the selected text in the quote text
(as in Apple Mail, but not in Fastmail...): Select the wanted text and press 'A' to reply with that selection
FMail2 supports native macOS tabs and remembers the tabs as they were when you closed the program (no more then 6 tabs are reopened; otherwise Fastmail complains there are too many connections)
Decide what folder you want to use for your Downloads
Have notifications even when FMail2 is not in the foreground, no need to have the email window open
Choose your Notification sound
Use the Arrow Keys and/or Spacebar to navigate your mails
Supports horizontal swipes for navigating the history
You can override Dark- or Light Appearance, when an email doesn't show well in a certain mode
Run the Fastmail beta version (if some functions do not work anymore, start by disabling this option in the Settings)
Can show the number of unread emails in the Dock icon
The title bar has history buttons, shows the used Fastmail url (in red when beta), a Search field for searching inside an email with Previous and Next buttons, text scale buttons and a padlock for selecting to hide when FMail2 does not have the focus
You can choose to automatically hide FMail2 if it loses focus; use this setting when you use tabs 👏
Native printing of emails
Secure - Not running in your browser means you are better protected against web tracking
Secure - Mouse over will show you all links, so you know before you click
Secure - A contextual menu lets you check the real address of an URL, also a shortened one, before you open it
Copy a RFC-5322 compliant Message-ID to the clipboard via a shortcut, the Edit menu or the contextual menu and paste it in an application that supports hyperlinks.
Later on, open that link in FMail2 or in any other email client that supports the RFC-5322 compliant Message-ID (such as Apple Mail)
Automatic updates (if you want)
Localized in English, French and Dutch
Less then 10MB in size
(compare to 300MB+ for an Electron -good for the developer, bad for the user- based application, you can store 30 applications of the FMail2 size in the space taken by 1 Electron application...)
If you find FMail2 useful you could
If Fastmail decides to change the underlying code, there is no guarantee I can keep FMail2 alive.
