The unsubscribe button already works in the iOS and Android apps, but only for Proton domain addresses. When an email is sent to a SimpleLogin / Proton Pass alias, the unsubscribe option shows up on the web app but not in the mobile apps.

Since a lot of us rely heavily on aliases, it would be great to have the same unsubscribe experience on mobile that already exists on the web.

This would make it easier to clean up mailing lists on the go, improve consistency across platforms, and let users unsubscribe in a more privacy-friendly way without clicking external links.

This isn’t about adding new detection — just extending the existing alias unsubscribe feature to iOS and Android.
