Thanks to recent revitalization of development by @bengotow we were able to bring Mailspring back as an official package on Solus. Which made me happy as a long time user of Mailspring. For anyone on Solus, after today’s (2026-04-24) you will be able to install Mailspring through the package managers (Discover, Gnome Software, or Solseek) or through the command line sudo eopkg it mailspring.
