Put a super pretty looking button in the sidebar to subscribe to the newsletter, and on subsequent visits have a "take the survey" button show up.
As a bonus, that doesn't get blocked by adblockers, and doesn't annoy those who aren't interested. I might be bored and see what the questions of a survey are, and maybe take it if they're interesting, but not if it's a pop-up.
On first visit, it pops up a modal subscribe email dialog.
On a second visit, a distracting large survey thing slid in from the bottom.
