About Us

Packetderm, LLC is a pioneering force in the realm of online privacy, with a legacy that spans over two decades. Our roots can be traced back to the privacy and security usenet groups of the mid-1990s, where we actively contributed to the mixmaster remailer network.

With the launch of Cotse privacy services in 1999, we redefined the way our subscribers approached email privacy. Our innovative solutions not only withstood the test of time but also became the benchmark for what users expect from privacy-focused services today. Now, in 2024, we are proud to present CodaMail, the evolution of Cotse, designed to seamlessly merge all of our services and domains into a single, cutting-edge platform.

Throughout our journey, we have fiercely maintained our independence, ensuring that our sole accountability lies with our subscribers.
