Unwanted string with Json inserted from Azure Queue for Logic App

Question

I am inserting a message in the Azure queue as Json String as shown below

[Serializable]
public class Person
{
    public string FirstName { get; set; }
}

And on the insert in queue, I should receive mail. I am expecting the mails content to be json string but I am receiving the content of mail as shown below

@ string 3http://schemas.microsoft.com/2003/10/Serialization/� {"FirstName":"Vikram"}

Now what is this extra strings at the beginning "@ string 3http://schemas.microsoft.com/2003/10/Serialization/� " in the content and how to remove it.
