title: Cant' reach https://api.sendgrid.com/v3/mail/send endpoint (?)
body: <p>I've got an issue with sending e-mails with PHP using Sendgrid - I try to send the simpliest e-mail, I get 202 status, but no e-mails are delivered. </p>
  
  <p>I've already contacted with SendGrid support team to confirm that my API KEY is valid and has correct permissions.</p>
  
  <p>I use:</p>
  
  <pre><code>- PHP 7.3.0
  - Composer 1.8.3
  </code></pre>
  
  <p>This is my composer.json:</p>
  
  <pre><code>{
    "require": {
      "sendgrid/sendgrid": "^7.3",
      "sendgrid/php-http-client": "~3.9.6"
    }
  }
  </code></pre>
  
  <p>I've produced the simplest test endpoint to send an e-mail. It's in here -> <a href="http://konfiguratorszkolen.pl/send-email/test.php" rel="nofollow noreferrer">http://konfiguratorszkolen.pl/send-email/test.php</a></p>
  
  <p>The code in this PHP looks this:</p>
  
  <pre><code>&lt;?php
  require 'vendor/autoload.php'; 
  
  $email = new \SendGrid\Mail\Mail(); 
  $email-&gt;setFrom("testemail1@gmail.com", "Example User");
  $email-&gt;setSubject("Sending with Twilio SendGrid is Fun");
  $email-&gt;addTo("testemail2@gmail.com", "Example User");
  $email-&gt;addContent("text/plain", "and easy to do anywhere, even with PHP");
  $email-&gt;addContent(
      "text/html", "&lt;strong&gt;and easy to do anywhere, even with PHP&lt;/strong&gt;"
  );
  $sendgrid = new \SendGrid("MyValidAPIKey");
  try {
      $response = $sendgrid-&gt;send($email);
      print $response-&gt;statusCode() . "\n";
      print_r($response-&gt;headers());
      print $response-&gt;body() . "\n";
  } catch (Exception $e) {
      echo 'Caught exception: '. $e-&gt;getMessage() ."\n";
  }
  ?&gt;
  </code></pre>
  
  <p>Sendgrid support team says that I don't send POST request to the <a href="https://api.sendgrid.com/v3/mail/send" rel="nofollow noreferrer">https://api.sendgrid.com/v3/mail/send</a> endpoint. But shouldn't $response = $sendgrid->send($email); do that job?</p>
  
  <p>What might be the issue? How can I reach the endpoint?</p>
  
  <p>I want to add, that this kind of code worked perfectly in May. It stopped a few weeks ago. What am I doing wrong?</p>
