Newsletter Workspace
Built for newsletters, not generic email.
Letterboxx gives newsletters their own Mac workspace with smart filters, custom Letterboxxes, optional badges, and a dedicated reader separate from your personal inbox.
A better home for your newsletters.
Import newsletter copies from the mail folders you choose, organize them locally, and read in a dedicated home that's not your personal inbox.
Your newsletters, minus the inbox.
A dedicated Mac app for the things you actually meant to read.
Clean View does the tidying.
Trim trackers, ads, embeds, and clutter before they reach your eyes.
Highlight like you mean it.
Save the good bits in familiar colors, right where you found them.
Give every newsletter a home.
Letterboxxes work like folders, keeping subscriptions stored, sorted, and out of your inbox.
Flip to the nerdy side.
Reveal sender, source, composition, and Clean View details without leaving the reader.
Let the mail sort itself.
Simple Auto-Delivery rules send recurring newsletters where they belong.
Make the list feel like yours.
Adjust type, density, badges, dates, and status icons until it feels right.
Keep your library tucked away.
Encrypted backups protect newsletters, Letterboxxes, rules, highlights, and settings.
Choose your reading mood.
Light, dark, e-ink, newspaper, Kitty Cat, and more. Because this is a Mac app.
Everything newsletters need.
Nothing your inbox does not.
Letterboxx brings newsletter reading, organization, privacy, search, highlights, and backup into one focused Mac app.
Calmer Reading
A focused newsletter reader for the Mac.
Read newsletters in a quieter queue with sender context, quick actions, and a layout made for recurring issues instead of one-off email threads.
Clean View
Cleaner articles without the inbox clutter.
Clean View strips away noisy email HTML, embeds, trackers, and layout junk so long-form newsletters feel faster, calmer, and easier to finish.
Custom Letterboxxes
Organize newsletters by topic, sender, or ritual.
Create Letterboxxes for work, investing, design, local news, or weekend reading, then keep each one separated from the rest of your mail.
Auto-Delivery
Route recurring newsletters automatically.
Smart rules file newsletters into the right Letterboxx as they arrive, helping your reading list stay organized without another weekly cleanup habit.
Highlights + Recall
Save the best ideas and find them again.
Highlight useful passages, revisit saved lines, and turn newsletters into a library of ideas instead of a stream that disappears after reading.
Message Diagnostics
Understand what each newsletter contains.
Inspect sender identity, source details, composition data, and Clean View changes when a newsletter looks strange or deserves a closer look.
Mac-First + Private
Private, local-first, and made for Mac.
Connect Gmail or IMAP, import newsletter copies without moving originals during normal import, and protect your local reading library with encrypted backup and restore tools.
One newsletter price.
A better home for all of them.
Organize newsletters. Read cleaner. Find them again.
