SendGrid sending not Emails using API Example in documentation

Question

I am using same example as given in documentation :

public static void main(String[] args) throws Exception {

    Email from = new Email("****@gmail.com");
    String subject = "Sending with SendGrid is Fun";
    Email to = new Email("****@gmail.com");
    Content content = new Content("text/plain", "and easy to do anywhere, even with Java");
    Mail mail = new Mail(from, subject, to, content);
    SendGrid sg = new SendGrid("API KEY");

    Request request = new Request();
    try {
        request.setMethod(Method.POST);
        request.setEndpoint("mail/send");
        request.setBody(mail.build());
        Response response = sg.api(request);
        System.out.println("response.getStatusCode() ------------------- "+response.getStatusCode());
        System.out.println("response.getBody() -------- "+response.getBody());
        System.out.println("response.getHeaders() -------- "+response.getHeaders());
    } catch (IOException ex) {
        throw ex;
    }
}

I can even see response code as response.getStatusCode() ------------------- 202

But still I dont get any emails. Any more configuration needs to be done on sendgrid side which I may be missing?

I'm getting mails.

The steps I followed to get the mail are as follows :

I signed up for SendGrid.

Steps :

Go to the Dashboard and select "Integrate using our Web API or SMTP relay"

Select Web API option.

Select your desired programming language to integrate. Here, select Java.

Put an API key name and click on create key to generate the random value for it.

Go down on the same page to generate key and click on the check box "I've integrated the above code."

Note : Implement the code given and run it. It gives no error. Then, do this :

Then, click on the button Next:Verify Integration.

It will land to the verify page.

Click on verify Integration button. If it gets success.

Then, it will show this :

Now, the code :

Output :

response.getStatusCode() ------------------- 202
response.getBody() -------- 
response.getHeaders() -------- {Server=nginx, Access-Control-Allow-Origin=https://sendgrid.api-docs.io, Access-Control-Allow-Methods=POST, Connection=keep-alive, X-Message-Id=ZBe5wF5WQN-TD9P4X9QEJw, X-No-CORS-Reason=https://sendgrid.com/docs/Classroom/Basics/API/cors.html, Content-Length=0, Access-Control-Max-Age=600, Date=Sat, 21 Mar 2020 14:09:25 GMT, Access-Control-Allow-Headers=Authorization, Content-Type, On-behalf-of, x-sg-elas-acl}

Mail box : Check the Spam Folder of your mail.

I am following the same, but no email in inbox or spam, no email activity in SendGrid too. I believe this might be the issue https://stackoverflow.com/questions/42214048/sendgrid-returns-202-but-doesnt-send-email – Nagendra Singh Mar 21 '20 at 14:43
@NagendraSingh I have done the whole process. For me, it's working. Why is it not working for you I don't know ? – Anish B. Mar 21 '20 at 14:43

I am using Heroku and using SendGrid as addon – Nagendra Singh Mar 21 '20 at 14:44
@NagendraSingh Can you try by enabling IMAP on the particular email address ? – Anish B. Mar 21 '20 at 14:47
@NagendraSingh It should work. Refresh mail box continously and check spam folder. SendGrid takes time to send mails what I have seen. – Anish B. Mar 21 '20 at 14:49

I reauthorized the addon and now it worked. Thanks @Anish – Nagendra Singh Mar 21 '20 at 14:58
