Use hidden.bs.modal event to detect modal close. and this validation-summary-errors is the class that is added for validation errors div. so you can remove it, empty it or hide it as per your requirement.

$('#modalSendEmail').on('hidden.bs.modal', function (e) {      
    $('.validation-summary-errors').remove() 
    //or 
    //$('.validation-summary-errors').empty() 
    //or 
    //$('.validation-summary-errors').hide()
})
