About
Letterboxx takes newsletters out of the inbox and gives them a place of their own. It connects to the mail accounts you already use, copies the newsletters out of the folders you nominate, and keeps them in a local library on the Mac. Publishers become Letterboxxes you can group however you think about them, and delivery rules file each newsletter by sender, subject or content without you touching it. Clean View strips the trackers, ads and stray email markup so a newsletter reads like an article rather than a web page in an email frame, and highlights plus reading history make the good ideas easy to find a month later. Storage is local, with encrypted backup and restore. It needs macOS 15.6 or later.
