There are two ways to use Flux.
First way: Use external tools to collect email addresses through user engagement.
In this case, Flux's call-to-action button triggers any engagement tool you can find on the web, such as surveys, quizzes, or polls.
Some popular choices: Tally, Typeform, Google Forms for surveys and quizzes, Elfsight for social media widgets, reviews, chats, e-commerce, podcasts, video, and lots of other widgets.

Second option: Use Flux's Call-To-Action button to open a new tab with an external web page.
This can be your sales page for subscriptions or memberships, but also the landing page for an event, a podcast or any other website.
In both cases, Flux will make sure that only the users who are in your selected segment will see your flow.
