HOW TO Filter notifications
1 Reduce the barrage
having too many notifications can drain your battery, and be a pain to deal with. in your iPhone’s Watch app, tap Notifications in the my Watch tab, then toggle off any app with notifications you don’t want to receive on your wrist.
2 Clear the backlog
you can view all of your recent notifications by swiping down from the top of the Watch screen. if you feel like you have too many, deep press on one until Clear All appears. tap that to dismiss all unattended notifications.
3 Only allow VIP emails
in mail on iPhone’s mailboxes list, tap ViP, then Add ViP, to choose contacts for whom you want a buzz. in my Watch > mail, tap Custom, then include mail, and uncheck mailboxes you don’t want notifications for. Keep ViP ticked.
