Help to deserialize complex JSON

I need to deserialize this JSON:

{
    "emails": {
        "items": [
            {
                "id": 1,
                "email": "[e-mail]"
            },
            {
                "id": 2,
                "email": "[e-mail]"
            }
        ]
    }
}

Into this object using Marshmallow:

{
    "emails": [
        {
            "id": 1,
            "email": "[e-mail]"
        },
        {
            "id": 2,
            "email": "[e-mail]"
        }
    ]
}

How can I do it?

I tried this way, which I found more intuitive, but it did not work:

class Phone(OrderedSchema):
    id = fields.Int()
    email = fields.Str()

class Contact(Schema):
    key = fields.Str()
    phones = fields.Nested(Phone, load_from='phones.list', many=True)

Pluck is work in progress. It is not available yet.

What version of marshmallow are you using? Can you edit your example so that the data and the schema match?
