Subject: Critical UX Failures — Label Management & Filtering

To the Proton Mail Product and Development Teams,
I am writing to request immediate UX improvements regarding how labels and filters are managed in your system. The current workflow for managing pervasive labels shows a staggering lack of respect for users operating complex inboxes. While your privacy and security frameworks are excellent, your basic organizational tools are actively hindering productivity and require a massive overhaul. It is unacceptable that you bill us 30% more—with an added 40% exchange rate penalty for Canadian users—for the exact same unresolved pain points we have endured for over five years, all while increasing your fees to fund tech charities instead of fixing your core product.

Please address the following glaring usability gaps immediately:

Inability to Filter by Multiple Labels: It is unacceptable that users cannot execute a basic search or filter combining two or more labels simultaneously. This is standard functionality in almost every other email client.

Search Box for Labels: For users with hundreds of labels, manually scrolling through an endless dropdown list is absurd. Implement a simple text search box directly above the label menu for immediate filtering.

Automatic Label Sorting: Creating a new label dumps it at the very bottom of the list, forcing users to navigate into the settings menu to manually drag and drop it into alphabetical or logical order. Auto-sorting must be standard.

Implement a "Clear All Labels" Button: Users should not have to open the label dropdown and manually uncheck 10+ individual labels one by one when a thread accumulates a massive block of incorrect tags. There needs to be a single action button to strip all tags from a selected email instantly.

Traceability for Auto-Labeling: When an email arrives with unexpected labels, there is no diagnostic indicator explaining why it was labeled. The UI needs to show whether a label was applied by a specific Custom Filter, a Sieve Script, or inherited via Conversation Grouping.

Mass Edit Controls: Managing label sprawl across historical emails from a specific sender is overly manual. We need a streamlined way to mass-edit or purge specific label combinations across bulk search results without fighting the current clunky dropdown menu.

Your organizational UX is fundamentally broken for power users who rely on high-volume filtering. Please escalate these missing basic features to your development roadmap immediately.
