Adding "web version link" in email by sendgrid

Question

How do I add a link to a web version of my sendgrid emails like "having trouble reading this email, click here"?

[EDIT] I use a php sendgrid library include "sendgrid-php-master/SendGrid_loader.php";

And I use this code and it doesn't work :

$mail = new SendGrid\Mail();
....
$mail->setHtml('<a href="[weblink]">View this email in your browser</a><br />'.$sg_html_code);
...

Answer 1

Just to confirm what Lirianna said, here you have the answer from Sendgrid support team to the same question:

Using [Weblink] will only be supported when using our Marketing Campaigns tool. To use this in a transactional template, you would need to create and host that link yourself.

Answer 2

Please be aware that SendGrid terminated the [weblink] and [unsubsribe] in 2017 (30/09/2017). You need to migrate with the new migrating toolkit.
