How to make more effective use of Mail on iPhone and iPad
If you use an iPhone or iPad to get things done, you really should make sure Mail on your device is working with you, not against you.
Use VIP for important items, that’s what it is for
The last thing anyone needs is constant notifications each time a new email lands in an account, which is why most of us disable them (Settings>Mail>Notifications). That’s fine, but some messages are urgent — which is where the VIP feature is helpful. I use it for important people such as close friends, family, work colleagues and for any business that may be in progress. That way, I get told when a new message appears from any of these people.
