How the signup form works

Every live project on your hub has a signup form. Visitors enter an email address and choose the button. That is all we ask for.

Under the button, every visitor sees: "From this creator only. Unsubscribe anytime. Subscriber emails and names are never sent to AI prompts." with a link to the privacy policy.

After someone signs up

• They see a clear confirmation that they are in.
• They can optionally tell you what drew them in and how they found you. It is clearly marked optional and their signup is already complete.
• If the project has a published magnet with an email sequence, the welcome emails start.

Signing up twice with the same email does not create a duplicate. Along with the email, Seamline records where the visitor came from (any source tags on the link, and the referring page) and an approximate city. We never send a visitor’s address to an outside location service.
