Scope of our work

Obálka

  • Webmail client
  • Encryption and key handling
  • Threads, attachments and search
01 / Initial need

The problem to solve

The team needs to manage its own email and work comfortably with conversations. Receiving, storing and reading messages must form one usable workflow.

02 / Our solution

What we built

We built an email application covering receipt through to reading. It includes encrypted storage, browser-based mailbox unlocking, conversation threads, folders, search and attachments.

03 / Practical use

What the solution enables

Users find related messages in one thread, locate attachments and reply directly from the mailbox. The organisation manages the email application itself.

Technology and how it works

Automation handles message receipt, encryption, delivery and threading. The application uses OpenPGP and browser-based key handling. The standard mailbox does not use a language model to read email.

  • Email automation
  • OpenPGP
  • Self-hosted operation
