Currently, every push notification received on iOS displays the ProtonMail app icon, regardless of who sent the email.

I would like the notification to show the sender’s own brand icon or favicon instead of the fixed ProtonMail logo.

This would make it much easier and faster to recognize the source of each email directly from the lock screen or notification center.

ProtonMail already displays sender favicons beautifully inside the inbox. Extending this same experience to iOS push notifications would greatly improve the overall user experience.

Thank you for considering this feature!
