MailMate is a Communication app for Mac.

About

MailMate is an IMAP email client for macOS. Its beta cask installs the MailMate application and provides the emate command-line binary. The official site lists macOS 10.12 or later as a requirement.

Notable features include:

  • Extensive keyboard controls and Markdown-integrated email composition.
  • Advanced search conditions, drill-down search links, and smart mailboxes.
  • Automatic signature handling, message tagging, and multiple notification methods.
  • OpenPGP and S/MIME encryption and signing, plus alternative message-viewer layouts, including a widescreen layout.
  • Flexible integration with third-party applications.

Install the beta variant with brew install --cask mailmate@beta. It conflicts with the separate mailmate cask, so the two variants cannot be installed together. The cask also makes emate available in Homebrew's binary directory.
