Personalization functions: webonly
The {webonly} block is used to mark a piece of code to only be visible in the webversion of the message. Would this template be displayed via the mail (because someone clicks on the link), the code inside the tags will not be rendered.
Example
{webonly}
Click <a href="{somepage}">here</a> to go to the homepage
{/webonly}
In the example we use the {webonly} block to hide the link to the homepage if the user is in their mail.
