Title: Proton Mail lacks essential metadata and message‑linking needed for professional case‑tracking workflows

Message:

I am an Executive Secretary of the Animal Protection Activists Network operating in Greece.
My work requires maintaining a structured case‑tracking system using external tools such as Excel and Drives, while Proton Mail serves as the primary communication channel with members of the cabinet, ministers, high ranked legal entities, police officials and multiple recipients.

However, Proton Mail does not provide the basic metadata or message‑linking information required to integrate email communication with external case‑tracking tools. As a result, it is impossible to maintain reliable records, trace communication chains, or organize multi‑recipient correspondence using Proton Mail alone.

Specifically, Proton Mail lacks:

• message tags or case identifiers
• linking between sent messages and replies
• visibility into which recipients responded
• safe archiving of sent messages (moving a sent message to a folder does not create a separate stored copy)
• predictable message‑handling behavior
• follow‑up reminders or overdue‑response tracking
• grouping of related communications
• timeline view of a case or incident
• stable Bridge integration for external workflow tools

These are not requests for CRM functionality.
They are basic operational requirements that any professional user needs in order to connect Proton Mail with external tools and maintain safe, traceable, structured communication.

I request that Proton Mail consider adding essential metadata, message‑linking, and safe archiving features so that professional users can reliably integrate Proton Mail into their existing workflows. Thank you
