Apple Mail comes with everything you need in an email client, but super users may want more advanced features. Mail add-ons offer advanced labeling, simplified interfaces, new message notifications, versatile filters, enhanced security, artistic stationery, and more. Here are the most popular Mac Mail add-ons.

MailSuite includes four powerful components: MailTags, Mail Act-On, Mail Perspectives, and SigPro. These components let you add tags, keywords, notes, and expiration dates to emails in macOS Mail.

The MailTags component integrates tags with searches, rules, smart mailboxes, calendars, reminders, and project management software for near-perfect and semi-automated custom email organization.

MailSuite includes Act-On, a Mail plugin that saves time with keyboard shortcuts. You can set up keyboard shortcuts for labeling, moving or redirecting messages.
