Sendgrid change href of link : <p>I am using Nodejs with Express and I am sending an email through Sendgrid, but Sendgrid is changing the href link</p>

<pre><code>var emailText = '&lt;!DOCTYPE html&gt;&lt;html&gt;&lt;head&gt;&lt;meta charset="UTF-8"&gt;&lt;/head&gt;&lt;body&gt;&lt;a href="https://www.google.com"&gt;Here&lt;/a&gt;&lt;/body&gt;&lt;/html&gt;'
var from_email = new helper.Email('contact@test.com');
var to_email = new helper.Email('contact@test2.com');
var subject = 'Test';
var content = new helper.Content("text/html", emailText)
var mail = new helper.Mail(from_email, subject, to_email, content);                                            
var request = sg.emptyRequest({
    method: 'POST',
    path: '/v3/mail/send',
    body: mail.toJSON(),
});
sg.API(request, function(error, response) {
    if (error) {
        console.log('Error response received');
    }
    console.log(response.statusCode);
    console.log(response.body);
    console.log(response.headers);
});
</code></pre>

<p>When the email arrives the following link appears:</p>

<p><code>https://u4006412.ct.sendgrid.net/wf/click?upn=rOQ9fjZGp5r0JyNfoC02LbL.....</code></p>

<p>Could someone help me solve this problem?</p>
