Web/Android/iOS: Google released a small update to itsInbox apptoday that allows you to set custom snooze times to help adapt the app to your preferences.
you’ve got the option to now set up custom times for morning, afternoon, and evening snooze.
All you better do is set an email to snooze, pick a custom time, and then Inbox will ask if you want to set that as your morning, afternoon, or evening preference.
