Here is something nobody tells you when you start a website: traffic is rented. Your Google rankings can disappear overnight. Your Facebook reach can get cut in half by an algorithm update. Your ad account can get suspended. None of it belongs to you.
Your email list does.
It’s the only channel where you have a direct line to your audience that nobody else controls. No algorithm in the way. No ad budget required. You send an email, it lands in their inbox, they read it — or they don’t. But the relationship is yours.
This is how to build one.
Step 1: Get the right tool
The tool that runs your email list is called an email service provider (ESP). It handles sign-ups, stores your subscribers, and sends your emails. Don’t try to do this with Gmail or Outlook — you’ll hit limits fast and there’s no way to manage a list properly.
The one I use and recommend is Kit (formerly ConvertKit). It was built specifically for people who create content online — bloggers, course creators, newsletter writers. It has proper automation, subscriber tagging, and a clean sequence builder, without the complexity of the enterprise platforms.
The free plan covers up to 10,000 subscribers, which means you can run a proper email operation before spending a penny.
Step 2: Create a sign-up form
Kit lets you create embedded forms and landing pages directly inside the platform — no extra tools required to get started. If you want a more custom opt-in page built into your WordPress site, this guide to WordPress landing pages covers how to do it with Elementor and connect it straight to your Kit list.
Put your form somewhere visible. The best places:
- At the end of every article
- In a sidebar or header
- A dedicated landing page you can link to from anywhere
Don’t overthink the design at this stage. A clean form with a clear headline and a single button is all you need. You can refine it once you have data.
Step 3: Give people a reason to sign up
The single biggest lever for growing your list is having something worth signing up for.
A good lead magnet doesn’t have to be complicated — a short PDF, a checklist, a resource list, a free first chapter. Whatever your audience is trying to accomplish, make something that helps them take the first step. Put it behind your sign-up form.
The question to ask yourself: would I trade my email address for this? If the answer is yes, it’ll work.
Step 4: Write a welcome sequence
When someone signs up, don’t leave them in silence. Kit lets you create an automated sequence — a series of emails that go out over the first few days after someone joins your list.
A simple welcome sequence might be three emails:
- Deliver the lead magnet (if you have one) and say who you are
- Share something genuinely useful — your best article, a tip they can use today
- Tell them what to expect from your emails going forward
That’s it. Three emails, written once, running automatically for every new subscriber. It’s the most valuable hour you’ll spend on your email marketing.
Step 5: Send consistently
The fastest way to kill a list is to sign people up and then disappear for three months. When you eventually send something, half your subscribers won’t remember who you are and will unsubscribe or mark you as spam.
Send something at least once a month. Once a week is better. The content doesn’t have to be long — a useful tip, a short observation, a link to something worth reading. Consistency matters more than length.
The relationship is the asset. Every email either builds it or erodes it.
The tool, again
If you take one thing from this: get started. An imperfect email list built this week is worth infinitely more than a perfect system you’re still planning in six months.
