The #1 Newsletter Marketplace

Smart Insights, Expertly Crafted Newsletters.

Formerly Duuce, now reimagined as LetterTrader.

At LetterTrader, we’re a dedicated team on a mission to make newsletter acquisitions smarter, safer, and smoother for everyone.

Formerly known as Duuce, LetterTrader was the first and only marketplace built exclusively for newsletters. In 2025, we reimagined it from the ground up — creating a modern, verified, and professional space for creators and buyers who take newsletters seriously.

We don’t just list newsletters — we understand them. Every publication on LetterTrader represents real effort, real audiences, and real value. That’s why we’ve built a platform grounded in clarity, quality, and genuine support.

Our approach is built on three key principles

Verified. Transparent. Authentic.

Every newsletter listed on LetterTrader is fully verified for ownership, performance, and revenue accuracy. Buyers can make confident decisions, and sellers can showcase their assets with credibility.

Support at Every Step.

From valuation to final transfer, our team provides clear, personal guidance. We help simplify the process, answer questions, and ensure every transaction feels secure and fair.

Newsletters Only. Always.

This isn’t a general business marketplace — newsletters are our world. That focus allows us to deliver unmatched insights, precise valuations, and a seamless experience for both sides of every deal.
