Hi! I am integrating some (non-Klaviyo) surveys into my email campaigns. For reporting purposes, I would like to be able to pass in some dynamic values to the URLs in my “form” links within the campaign. (For example, if a user clicks a link, I could see in the reporting which campaign they clicked on.) My questions:

First: When composing an email campaign, is there a template tag I can use that repeats the subject line used in that campaign email? For example, if the subject is:

Bananas are 50% today only

Then let’s say a template tag like

{{ subject }}

…would resolve to:

Bananas are 50% today only

Second: If that doesn’t exist, is there another template tag of a campaign identifier, or some other way to identify the campaign? (I see that I could use {{ date }}.)

Third: Does Klaviyo’s template language include a mechanism for URL-encoding strings?  For example, to take the {{ subject }} and convert it to:

Bananas%20are%2050%25%20today%20only

…so it could be usable within a URL parameter.

Thank you!
