Inkletter: E-Ink Newsletter Live

Gmail newsletter reader for Boox and E-Ink. Google sign-in is read-only — the app never sends mail. Paginated, offline, no ads. Your messages stay on the device. Inkletter isolates Gmail newsletters into a calm black-on-white reader for Boox, Onyx, Hisense, and similar e-paper devices. WHY INKLETTER? Newsletters get buried in Gmail between work mail, promotions, and alerts. Inkletter automatically detects newsletter messages (List-Unsubscribe header) and gathers them into a dedicated library. No infinite scroll, no noisy UI chrome: a reading flow designed for electronic paper and longer sessions. HOW IT WORKS 1. Sign in with Google (secure OAuth, read-only access). 2. Inkletter syncs your Gmail newsletters to the device. 3. Open a newsletter and read page by page (tap left / right). 4. Keep reading offline from the local cache. 5. Sign out to clear tokens and cache, or revoke access in your Google Account permissions. KEY FEATURES • Secure Google Sign-In — gmail.readonly scope only • Automatic newsletter detection • Organized library built for reading, not inbox triage • Paginated E-Ink reader (high contrast, reduced ghosting) • Offline reading after sync • Font size and margin controls • French and English UI • No ads in the reading experience • Inkletter Pro (Google Play subscription): extended sync and export SUPPORTED DEVICES Inkletter targets Android E-Ink phones and tablets — especially Boox, Onyx, Hisense, and other e-paper readers. It can run on standard Android phones too, but it is purpose-built as an e-ink newsletter reader for e-paper displays. PRIVACY AND DATA CONTROL • Read-only Gmail — the app never sends, edits, or deletes email on your behalf • OAuth tokens encrypted on device • Local cache only — no Inkletter backend storing your newsletter content • Privacy policy: https://www.inkletter.app/privacy-en • Delete data / revoke access: https://www.inkletter.app/delete-data • Contact: [email protected] WHO IS IT FOR? Busy professionals, students, and heavy digest readers (tech, finance, culture, productivity) who prefer quiet reading on an e-reader. If Gmail is where your newsletters arrive and E-Ink is where you want to read them, Inkletter connects the two without turning your reader into a noisy smartphone. Inkletter Pro is optional: start free, then choose a monthly or yearly Play subscription (trial availability depends on Play offers) when you need higher sync and export limits. Download Inkletter and turn your Android e-reader into a focused e-ink newsletter reader for Gmail.
