How to build a waiting list before you launch

In short
A Facebook post asking people to comment is a fine way to find out whether anyone cares, and it costs nothing. It stops working the moment you want to reach those same people at launch, because a comment is not something you can contact later. A pre-launch page is worth building when you have a launch date and need the interest to still be reachable when it arrives. It collects the address; sending anything to it is a separate job you still have to set up.
If you are getting ready to launch something, a product, a course, a shop, a service, the usual first move here is a Facebook post asking people to comment or send a PM if they are interested. It is free, it reaches the people who already follow you, and the replies tell you something real within a day. For finding out whether anyone cares at all, it is hard to beat and there is no reason to skip it.
When that is genuinely enough
If you are two weeks from launching to people who already know you, the post is the whole strategy. You will message them when it is ready, and building a page to collect fifteen addresses you could write on paper solves the wrong problem.
What a comment thread cannot do
Three things, and they all arrive at the same moment.
A comment is not a way to contact anyone. You can reply to it. You cannot reach that person at launch unless they happen to see your next post, and whether they do is not your decision. The people most likely to buy are the ones who replied to you weeks ago, and they are exactly the ones you have no way of reaching.
PMs stop being a list once there are more than a few. Forty conversations in a message request folder cannot be worked through in order on launch day. There is no way to mark who is still interested, and no way to write to all of them at once without doing it by hand, forty times.
You cannot tell how many are real. A post with thirty "interested" comments feels like demand, and some of it is people being supportive. An address somebody typed deliberately is a smaller number and a better one, because typing it took a decision.
None of that makes the post a mistake. What made it easy, that it costs nothing and lives on somebody else's platform, is the same thing that makes it useless the day you need to reach those people.
What a page like Signal actually does
Signal is two pages built around one action: get the email address. Everything that would compete with the form is deliberately absent, which sounds minor until you compare it to a homepage where signing up is one of nine possible clicks.
The parts that matter are the unglamorous ones. Validation happens when someone leaves the field rather than on every keystroke, so a half-typed address is not flagged as wrong while it is still being typed. There is a real success state, so nobody submits twice because nothing appeared to happen. There is a referral counter you can switch on if you want people to share it, and leave off if you do not. The form is endpoint-agnostic, meaning it posts wherever you point it rather than locking you to one provider.
What it does not do
It does not store the addresses and it does not send anything. Endpoint-agnostic means exactly that: the form needs pointing at something that keeps the list, whether that is an email service, a form backend, a spreadsheet, or your own server. Buying the template gets you the page a visitor sees and the behaviour around the form. Where the address lands is still a decision you have to make and connect.
It is also not a marketing plan. A page nobody arrives at collects nothing. The Facebook post is still what brings people; the page is what stops that interest evaporating before launch.
What it costs
Signal is ₱89, paid once, not a subscription. Hosting a static page like this is free on Cloudflare Pages or Netlify, with no trial that expires. A domain is the recurring cost, usually a few hundred pesos a year, and a free subdomain is fine for something you are only running until launch day.
Most email services have a free tier that covers a first list. Check the limits yourself before committing, and check that you can export the list and leave.
Common questions
Do I need a landing page if I can just collect comments on Facebook?
Not to find out whether people are interested, which a post does well. You need one when you want to reach those people at launch, because a comment gives you no way to contact anyone and a Facebook post reaching them again is not something you control.
What do I do with the emails once I have them?
Send something occasionally before launch, and tell them the day it is ready. A list nobody has heard from in four months converts badly, because people forget signing up. Two or three short updates is usually enough.
Is it worth building a waitlist page if I only expect twenty signups?
Twenty addresses you can actually email on launch day are worth more than two hundred comments you cannot. The question is not the number, it is whether you will still be able to reach them when it matters.
Where do the addresses go if the template does not store them?
Wherever you point the form. It posts to any endpoint, so an email service, a form backend, a spreadsheet, or your own server all work. That connection is a setup step you or whoever builds your site has to do once.
