iOS 7 Mail Notifications: How to Stop for Certain Folders

Hi all,

I'm currently on a mission to tame my email.

On my Gmail account, I recieve a lot of newletters and product advertisements, which, whilst are of interest to me, I don't want blocking up my main inbox. To get around this, I have set up a folder (Label) on Gmail, and Filters which will automatically move any newsletter/sales emails into a folder called 'Promotions'. I then have this folder visible on the front screen of my mail app.

Ideally, I would like to only recieve notifications for emails that arrive in my main inbox, and not be notified about these less important promotional emails. As I recieve quite a few throughout the day, I don't want unimportant emails causing my lock screen to light up several times, causing unneccesary battery drain.

My question therefore, is how can I disable notifications in iOS 7 Mail for specific IMAP folders? Or even for all folders other than the main inbox.

By doing so, it would mean I only get notifications about the emails that really matter.

I'm fairly sure this isn't possible, as I've checked through all the mail settings and notification centre options, but if anyone can offer any solution to this it would be greatly appreciated!

Many thanks in advance for you advice,

Luke
