App for surveys and marketing campaigns

Hi everyone!
I’m working on a Wix site and I need some advice on implementing a new feature.

We want to add a section with psychological tests. The idea is to promote these tests through social media campaigns. After users complete the test, their scores are calculated (sometimes with more complex logic than just adding up the answers), and then a summary email is sent to them with their results.

So far, we haven’t found an app that includes all these features, so we’ve been using Google Forms + Google Sheets to handle logic and automations.

However, we’d like to move everything into Wix, so that user data stays in one database and we can run follow-up campaigns more easily.

Do you know of any Wix apps or solutions that could help us achieve all of this?

Thanks a lot in advance!
