require_once ($_SERVER['DOCUMENT_ROOT'].'/demo/active-fit-club/sendgrid-php/lib/SendGrid/Exception.php');
$message = "Name : $name <br> Email : $email <br> Mobile : $mobile";
$sendgrid = new SendGrid('myapikey');
$email = new SendGrid\Email();
$email
->addTo("info#abc.co.uk")
->setFrom($email)
->setSubject("Contact mail")
->setHtml($message);
try {
$sendgrid->send($email);
$_SESSION['success'] = true;
header("location:url");
exit;
} catch(\SendGrid\Exception $e) {
// echo $e->getCode();
// foreach($e->getErrors() as $er) {
// echo $er;
// }
header("location:url");
exit;
}
}

Answer 1

Try moving setting the header before setting the SESSION variable and set $_SESSION['success'] to be 'true' instead of true:
try {
$sendgrid->send($email);
header("location:url");
$_SESSION['success'] = 'true';
exit;
}

im using the below code and its working.
$url = 'https://api.sendgrid.com/';
$apiKey = 'SENDGRID_API_KEY';
//api library from sendgrid
require_once "sendgrid/sendgrid-php.php";
$sendgrid = new SendGrid($apiKey);
$email = new SendGrid\Email();
$email
->addTo("to#example.com")
->setFromName("Fromname")
->setFrom("from#example.com")
->setSubject("your subject goes here")
->setText('')
->setHtml("your email html content goes here");
if($sendgrid->send($email))
echo "Mail sent";
else
echo "Failed";
you can get the library files from https://github.com/sendgrid/sendgrid-php
