### PM Action Plan (Next Best Moves)

- [ ] [INVEST] Rebuild account recovery and captcha flows because verification failures are a top-tier complaint → reduce account lockout churn
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Mixed

Users report: The market for privacy-first communication is consolidating as users move away from data-harvesting giants. Tuta Mail is well-positioned to capture this segment if it can resolve the technical instability that currently forces users to the web version, as persistent sync issues will eventually erode the retention gains of its encryption-first value proposition.

- 🔴 Inconsistent notification delivery and sync delays disrupt the app as a daily driver, leading to increased reliance on the web client.
- 🟢 The latest update addresses OS-level webview termination, moving the blank screen complaint from active to transitional status as users confirm the fix.
