Inbox Therapy for Apple Mail
Apple Mail is fine but lacks some critical features. This add-on allows you to quickly view emails in card view, swipe or arrow to the next batch, and quickly see which emails are important. I placed banners for potential phishing (with a short description why) and for subscriptions to see what is clogging the inbox. The phishing filter asks for permission to your contacts to notify you if that contact is actually not using the valid email address. Additionally, there is a sidebar with a view of just attachments you are looking for, or a method to batch-unsubscribe those tons of subscriptions and delete them en masse. You have a choice of looks: grayscale or color, with a small moon to toggle the view. You will need to allow permission three times to view Apple Mail and integrate contact checking. This is inbox therapy.
