Проблемы Сенгрид

Я использую java api. Я в документации по ссылке "https://github.com/sendgrid/sendgrid-java#without-mail-helper-class" копирую пример, как он есть на странице, я выполняю его, а почта не приходит. Разместите действующие адреса. Я не делаю исключения. Пожалуйста, этого не хватает

Ява

try {
SendGrid sg = new SendGrid(GlobalVariable.getInstance().getSendGridApiKey());
Request request = new Request();
request.setMethod(Method.POST);
request.setEndpoint("mail/send");
request.setBody("{\"personalizations\":[{\"to\":[{\"email\":\"[email protected]\"}],\"subject\":\"Sending with SendGrid is Fun\"}],\"from\":{\"email\":\"[email protected]\"},\"content\":[{\"type\":\"text/plain\",\"value\": \"and easy to do anywhere, even with Java\"}]}");
Response response = sg.api(request);
System.out.println(response.getStatusCode());
System.out.println(response.getBody());
System.out.println(response.getHeaders());
} catch (IOException ex) {
throw ex;
}
