Thanks for your reply.
I didn't receive any notifications. But when I look at the "Results" of the batch campaign, it shows nothing. I suppose this time we have to find another way out.
If you have other methods to track users' responses to a survey, please kindly share them with me. Appreciate it a lot!
Take out the Send Email step and replace it and replace it with something easy to trace like a Change Data Value that sets a Datetime field to {{system.datetime}}. Don't make any other changes and run it for the exact same lead you were just testing with. What happens?

I don't actually understand why you've chosen to use Velocity in this case. It's a lead field, and it presumably doesn't require encoding (you aren't running it through $esc.url()), so the link can be right in the email content with a {{lead.token}} in the query string.
