I know of some highly opinionated people who do not want to join any mailing lists for various reasons.
So maybe make the surveys accessible via in-game click-able links/QR codes.
As a side note, the in-game "what's new" can be better.
It's full of "refer to this not-clickable link". It can be at least a click-able link, or open up a much larger window/page/tab to explain what the event is about.
