Render form and save data This val provides a web-based interface for collecting email addresses. It features a dual-functionality approach: when accessed via a web browser using a GET request, it serves an HTML form where users can submit their email address. If the script receives a POST request, it implies that the form has been submitted, and it proceeds to handle the incoming data. Fork this val to customize it and use it on your account.
