A signup form (or subscription form) is a web form that collects a visitor's email address — and their consent — to add them to your mailing list. It is the primary way to grow a permission-based email list, whether embedded on a page, shown as a popup, or hosted as a standalone link.
Types of signup form
Common formats are embedded inline forms, popups, and hosted landing-page forms. Pairing a form with double opt-in confirms each address and keeps your list clean. Build one with Mailpro's signup form builder — see how to create a signup form with no code.
A signup form is one kind of web form; with a form builder you can also create online forms for registrations, requests or surveys without writing code.
Why it matters
A clear, well-placed signup form turns visitors into subscribers you own, unlike a rented social audience. Ask only for what you need, and set expectations up front. A signup form with CAPTCHA also stops bots from padding your list with fake addresses. See how to create a subscription form. Related: opt-in and landing page.
The first email after a sign-up is the one most people open. Our free welcome email templates give you 12 ready-made designs for greeting new subscribers and customers, and each one can be sent automatically.
