How do I collect emails from my page?

Publish your page with its form as it is, then open the project, go to Sign-ups and turn on Collect sign-ups. Every form on the project that asks for an email starts collecting, with nothing to change in your files, and Sign-ups shows which pages it found. Each sign-up appears there as it arrives, ready to export as a CSV, and you can send visitors to a thank-you page of your own. Forms that already send to another service, like Mailchimp, stay as they are. Sign-ups come with Pro and up.
