I had to open Mail and use its app selection menu instead:

To Reproduce…

Steps to reproduce the behavior:

  1. check the “default mail client” option on Mailspring
  2. try to click on a “mailto:” link (tested on Brave)
  3. Mail opens instead

Setup

  • OS and Version: Mac OS 11.6.1
  • Installation Method: .app
  • Mailspring Version: 1.9.2

Additional Context

Previously I had Thunderbird as default client.

I have the same issue… Can not launch Mailspring from Powerpoint when you want to share the presentation via email

It’s the other way around: set the default mail app in Mail to be Mailspring

  • Open the Mail app.
  • From the menu bar, choose Mail > Settings (or Preferences).
  • Click General.
  • Choose an email app from the “Default email reader” pop-up menu. —> Pick Mailspring
