Property blocks

The blocks property is used inside the main content section and holds an array of blocks that make up the mail. Every block in the array should at least have a type property to identify the block type.

{
    "from" : "info@example.com",
    "subject" : "Email with 2 columns",
    "content" : {
        "blocks" : [
            {
                "type" : "text",
                "content" : "I'm the first text block"
            },
            {
                "type" : "button",
                "label" : "I'm a buton"
            }
        ]
    }
}

The example above shows the input for an email with a text, followed by a button.

Use in columns

The blocks property is also used if make use of columns. Every column also has a blocks property that describes the blocks that are placed in the column.

{
    "from" : "info@example.com",
    "subject" : "Email with 2 columns",
    "content" : {
        "blocks" : [ {
            "type" : "columns",
            "columns" : [
                {
                    "size" : 6,
                    "blocks" : [
                        {
                            "type" : "text",
                            "content" : "I'm inside the first column"
                        },
                        {
                            "type" : "button",
                            "label" : "I'm also in the first column"
                        }
                    ]
                },
                {
                    "size" : 6,
                    "blocks" : [
                        {
                            "type" : "text",
                            "content" : "Second column"
                        }
                    ]
                }
            ]
        } ]
    }
}

The above example shows the two uses of the blocks property. First you see it in action as a property inside the main content section, and then twice when the blocks inside the columns are described.
