Automating Send-to-Kindle

Writing
, ,
  • A simple Python script that sends the selected MOBI files to a designated @kindle address and displays an OS notification when successful.
  • Tested on macOS Catalina.
  • Ready to be integrated with Alfred’s File Action.
  • #SMTP_SERVER, #YOUR_EMAIL_ADDRESS, #PASSWORD and #KINDLE_EMAIL_ADDRESS need to be filled out before deployment.
