Tuta (formerly Tutanota) is a secure email, calendar, and cloud storage service built and operated by Tutao GmbH, founded in 2011 in Hanover, Germany. All client applications are published as open source under the GPL-3.0 license, and the service uses end-to-end encryption with post-quantum cryptography to protect emails, calendar entries, and contacts. Tuta is bootstrapped and wholly owned by its two co-founders, with over 10 million users worldwide.

Sessy is an open-source email observability dashboard for AWS SES. It captures every SES event—deliveries, bounces, opens, clicks, complaints, and more—in a self-hosted dashboard that users own and operate. Sessy deploys via Docker or Kamal with SQLite by default and PostgreSQL as an option, requiring no AWS credentials beyond a webhook URL configured in SES.
