A consultant and a coffee shop do not sell the same way, so their signup forms should not look or read the same either. Each of these is built around how that kind of business actually makes money. Plain HTML, all of it: no builder, no embed script, no monthly bill, nothing phoning home to anyone. Kit 9 wires whichever you pick to your own server.
How well do they already know you?
That is the question that should decide the shape of your form, and almost nobody asks it. Same email address, four completely different conversations. Most sites pick one shape and use it on everybody.
Never heard of you
Don't show a field at all. Show a button. Clicking is a smaller thing to agree to than typing, and most people who click will finish.
Been here before
One image, one promise, one button, and nothing else on the screen competing for their attention.
Been burned before
Give the thing away first, right there on the page, and ask afterward.
Came looking for you
Long copy is fine. Make the whole argument and put the field at the bottom.
Form 1
The Booked Calendar
If you sell your time. Consultants, coaches, attorneys, accountants, agencies, anyone whose next step is a conversation.
You are not collecting addresses here, you are filtering for people worth an hour of your time. So the copy tells them what they walk away with whether or not they hire you, and it names what you will not do to them. The form asks for a first name on purpose: someone who will not type their name will not show up to the call either.
For people who came looking for you
Form 2
The Blueprint
If you sell what you know. Courses, templates, guides, memberships, newsletters, anything you made once and sell many times.
The headline is deliberately boring: free, a number, the thing, and exactly who it is for. The number does more work than any adjective you could reach for. A guide is worth nothing. 42 pages is a thing they can picture holding. And there is no field until they click, so the first yes costs them almost nothing.
For people who have never heard of you
Form 3
The First Order
If you ship something in a box. Online stores, makers, subscription products, anyone with a cart.
A discount is the only lead magnet that has ever really worked in retail, so lead with the number and keep the product in frame. The second line is doing the quiet work: the code buys you the address, but restocks and one-off runs are the reason they are still subscribed a year after they spent it.
For people who have been here before
Form 4
The Walk-In
If people come to you. Cafes, salons, studios, gyms, dentists, restaurants, any door with an address.
They are on a phone, standing somewhere, deciding whether you are worth the walk. So the offer is real, it is handed over first, and no email is required to claim it. The ask comes after that. Address and hours sit inside the form instead of down in the footer, because that is the question they actually came to answer.
For people who have been burned before
Take the whole set
Four folders, one per form, each holding the page and its own matching thank-you page, plus a short readme telling you which line to change to wire them together. If you only want one, every form above downloads as its own pair.
These are the front half. Kit 9 is the back half.
A form is just a box until something catches what comes out of it. Copy any block above and it will look right immediately, but it posts to /api/subscribe, and that endpoint has to exist on your server. Kit 9 builds it with you:
The endpoint on the server you already have, saving each signup to one small file you own.
The welcome email going out through your own domain, seconds after they hit the button.
The consent record written at signup: when, from where, and exactly what they agreed to.
A working unsubscribe link in every email, from day one, not bolted on later.
A copy in your inbox the moment anyone joins, so your list survives losing the server.
