Not receiving push notifications on iOS and Android

Push notifications for iOS and Android are sent each time you receive a new email to your inbox. There are no notifications for emails marked as spam. You will receive a push notification even if you open the message from another device.

There are multiple reasons you may not be receiving push notifications on your mobile device for incoming emails. In this article, we discuss some of the most common problems and their solutions.


Check that Push Notifications are enabled from the ProtonMail app settings. To do this, go to SettingsApp SettingsPush NotificationsNotification Settings and ensure that Show notifications is toggled on.

Ensure Google Play Services are enabled. We currently use Google Play Services to implement push notifications, although we will try to find other ways to support push notifications in the future.

  • Check if the snooze option is enabled in the ProtonMail app settings (Settings → account name → SnoozeNotifications Snooze). You will not receive any notifications when the snooze option is active.
  • Close and restart the Android app.
  • Log out of your account in the app and then log in again
  • Exclude the ProtonMail app from your device’s battery optimization or power-saving features. It is increasingly common for Android device manufacturers to improve battery life by aggressively closing apps. If ProtonMail is put to sleep in this way, you may not receive push notifications from the app. 

 Details for exempting ProtonMail from battery optimization or power saving vary by device. On Samsung phones running One UI, for example, open the Settings app, go to Apps and tap the three-dot vertical ellipse icon at the top right of the screen.
