Imagine getting a late-night email from someone you don’t really care about. Your iOS device immediately alerts you about the email, you get up in the middle of the night to check the email and then you realize all of it hasn’t been worth anything. iOS 6 has the perfect solution for you in the form of per person email alerts.
The feature is being offered through Mail app in iOS 6. Essentially, with the help of this feature, you can create a ‘VIP mailbox.’ It is a smart mailbox in which you can add all of your important contacts. In this way, you can read all your important mail, on priority basis, in a separate mailbox rather than having to scour through your regular inbox.
Not only that, you can also enter a different section of Notification settings through the settings of your VIP mailbox. In these Notifications settings, you can decide custom alerts for emails from your VIP contacts. You can also tweak the way these alerts will appear in the Notification Center. In this way, you can personally prioritize even among your VIP contacts.
The ‘Do Not Disturb’ feature has also been improved. Now, you can allow certain address book groups to reach you and ping you despite the silent settings while filter off all the other notifications. You can also scheduled a definite time when the silent settings will reign in.
