FMail

The current version is 1.9.3

For years now, I use Fastmail as my secure email provider

Have a look there if you do not use this service and you want to know what it can do for you.

For iOS and Android there are native clients, but not for macOS. The web interface used by Fastmail is excellent.
The big thing missing for me, is that the web interface cannot handle email links. So when you click on such a link it is the macOS Mail application that opens.
That is not what I want.
Enter FMail.

When you have installed FMail and have adjusted your default email client, an email link will open the FMail client with all provided fields filled.

There are a lot of extra options too.
Downloading is handled inside the application and the files are saved in your Download folder.
Want to look up an tracking number? One right mouse click away. 
If you use Fastmail from your browser switch to FMail. For free.
You won't regret.

FMail is a native Mac application, taking little resources on your system.
Runs on macOS 10.14 Mojave and higher.

Secure

Apple wants to keep all software on your computer safe. Therefore Apple wants that applications are Notarized and Sandboxed.

This can cause side effects when updating an older version.
If you run in such a problem, click the download link to get the updated application. 

FMail is written entirely in Swift, a safe modern language.
