Arrow Setting default mailto: email app

As BritTim says, this depends on the URL mailto: association set up on the computer. This is a combination of browser and operating system, and it's been messy to get this working correctly in the past. It works moderately well with Windows 10, as far as I can tell. To see how this works:
  • Log into your Fastmail account.
  • Go to Settings>Mail>Preferences
  • In the General section at the top of that page, click the link:
    Open email links from other sites in FastMail
    If you haven't done this before you will probably then need to answer a confirmation query. This is a one-time setup which you only need to run again if the Windows mail client associaiton is corrupted.
  • Now go to your website and click on the mailto: link you described. In Windows this should open a Launch Application window which lists Fastmail as an email application. Choosing FastMail and Open link will cause Fastmail to be started in the Compose screen with your email address in the To field. In my case, I can also choose the default Windows 10 Mail app, Yahoo! Mail, or Gmail. Each of these email clients or websites has automatic or manually controlled setup features which adds the email system to the Launch Application window which is opened when you click a mailto: link.
To see how you can manually change some of the mailto: URL associations, in Windows 10 search for Default app settings.
  • With Default apps selected at the left, click Email in the Choose default apps list.You can then choose an app to be used for Email by default. For my installation, the choices which work are Mail (Microsoft default email app in Windows 10), Outlook 2016, and Thunderbird.
  • If you scroll down to the bottom of the Choose default apps list and click Choose default apps by protocol, you can scroll down to MAILTO (URL:MailTo Protocol) and the same client you chose for Email in the Choose default apps list will be shown again.
  • The settings I just described allow you to choose the top choice which appears in the Launch Application window which appears when you click a mailto: link. The other selections (such as Fastmail) are set up through the webmail websites or through your browsers, I believe.
