Edison Mail has been a popular iOS email app for a while now, and today Edison Mail for Mac has launched. You can sign up for early access and referral codes here. I’ve been using it for about 2 weeks and think it’s a good email app for the Mac. Here are some features it brings: One click unsubscribe button, blocking people from emailing you, Quick Actions and swipe gestures, email threading and email templates, and an email assistant to help you manage subscriptions, trips, packages, entertainment, and bills/receipts.
However, do be aware that Edison scans your email for “interesting research” so it’s not an email service for the privacy-conscious.
