Summary
After concatenating the URL, I chose to add it to the text “Take the survey” via the Link button with Link to “Other” and then paste the AMPscript code to the Link URL column. Alternatively, it can also be done via html format in the content body using the RedirectTo() function:
<a href=”%%=RedirectTo(@surveyLink)=%%”>Take the survey</a>
