Onyx Gmail newsletter reader for E-Ink

Inkletter is built for Android e-paper first — including Onyx / Boox devices — so newsletter digests feel like a book, not a phone inbox.

Get Inkletter on Google Play

What Inkletter does

• Connects to your Gmail with read-only access
• Detects newsletter-style digests into a simple library
• Opens a paginated black-and-white reader tuned for E-Ink refresh
• Caches content for offline reading after sync
• Keeps ads out of the reading experience

Onyx / Boox setup (quick)

1. Open Google Play on the device and install Inkletter.
2. Sign in with the Google account that receives your newsletters.
3. Grant Gmail read-only access when prompted.
4. Pick a digest and page through it like a book.

Who it is for

People who already chose an E-Ink Android reader for deep reading — and still get buried in Gmail UI when newsletters arrive. Inkletter is not a general email client.

Pricing

Core reading is available on Google Play. Pro unlocks via Play Billing (monthly or yearly with a 7-day trial on the annual plan). Manage or cancel in Google Play subscriptions.
