stop iOS contact importing contact info from mail footers I recently changed from using the gmail app to the native iOS mail app on my iphone. 

Now when i search for a contact in the address book to make a phone call it seems to have pulled in a load of contact info from peoples email footers, i have some email accounts for work that i dont want to clutter up my contact book, is it possible to only set the 'search emails for contact info' setting to only apply to select email accounts ?
It's not available per-account, but the setting is adjusted in iOS 10 in Settings > Contacts. At the bottom of the list is a toggle for Contacts Found in Apps and that's what controls this pseudo-importing.
