If you don't want your iPhone incessantly beeping and buzzing all day long from unsolicited or unimportant emails, you may consider turning off Mail notifications. But then you will miss the ones that might be important from, say, your significant other, kids, parents, boss, etc. iOS 8 allows you to assign VIP status to your contacts, which lets you set notifications just for them. Here's how to do it:
1. To designate a contact as a VIP, go to your Mail app and tap on the VIP mail box.
2. Select "Add VIP," which will allow you to choose from your contacts (Note: their contact info must contain an email address).
