Este código que muestras, devuelve un json, tienes que revisar la pagina que hace la llamada, que es donde muestras el json que devuelve este código. Desde ahí, podrás leer el json correctamente.

Si nos lo muestras, intento indicarte

Error en formulario

Publicado por [abZeroX] (130 intervenciones) el 31/08/2017 05:37:52
Hola, la página contact.php que es la que se encarga de procesar el formulario devuelve es objeto JSON debido a tal como indica el mensaje
'La solicitud debe ser Ajax POST' por lo que en lugar de enviar directamente el form deberás obtener los datos de este y luego realizar la petición a través de Ajax.
