How can I create a simple email signup page with Wordfly that is captured in Tess?

I would like to lower the bar to allow people to sign-up for our mailing list. But I can't figure that out. I can create a signup page on wordfly, but how do those emails get into Tess and become future extractions that will receive emails from me? What we do today is to send people to our create-an-account page on our website. Which is a lot for most people with a curiosity.

thanks!
