Landing page
Prose Landing page — "Already gave us your email? Resume here."
Why it works
The link under the email gate in Prose's hair quiz goes to Prose's ordinary sign-in page, "Sign in as an existing customer", the same page the win-back ads use. There is no password: you type the email you gave the quiz and the page switches to "Check your email! You just received a link to log you in." The gate created an account without saying so, and this is the only way back into it.
