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

It's the latter half of 2021 and I tried using {{Weblink}} (capitalisation important) and it works just fine for me using the Dynamic Templates option.. YMMV
As per the official SendGrid documentation {{Weblink}} is available. Refer: SendGrid docmentation link
