PHP Sendgrid - Sender name is not being sent in mail - php

Question

I am working on PHP Sendgrid.. Everything is working fine.. but the problem is
I cannot add the Sender Name with from email somehow. I think it didn't captures the headers or what i have no idea.
P.S : I have executed this code on a separate server and it works. But when I try to send mail from the other server with same code it sends the email but doesn't set/show the Sender Name. Is it some server side issue I am using Laravel 4? please guide
$headers = "From: Coffe Email" . "\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
sendMail("myemail","mysubject","msg", $headers,$from="admin#email.com", "admin");
Function's Definition (sendMail) :
function sendMail($to, $subject, $message, $headers, $from = "", $from_name="", $to_name="")
{
require($_SERVER['DOCUMENT_ROOT']."/../sendgrid-php/sendgrid-php.php");
$email = new \SendGrid\Mail\Mail();
$email->setFrom($from, $from_name);
$email->setSubject($subject);
$email->addTo($to, $to_name);
$email->addContent("text/plain", strip_tags($message));
$email->addContent("text/html", $message);
$sendgrid = new \SendGrid($settings->send_grid_user);
try {
$response = $sendgrid->send($email);
print $response->statusCode() . "\n";
print_r($response->headers());
print $response->body() . "\n";
} catch (Exception $e) {
echo 'Caught exception: '. $e->getMessage() ."\n";
}
}
