A lead magnet funnel is the simplest funnel worth building. You give away something useful, someone leaves their email to get it, and over the next week or two you turn that quiet interest into a booked call. It sounds obvious, and yet most of the ones I see stop halfway. Here's the whole thing, piece by piece.
A lead magnet funnel gives away something useful in exchange for an email, then follows up with a short run of emails that build trust and invite a call. The freebie gets the email; the follow-up gets the call. Most fail because they collect emails and never follow up.
Who this is for: Coaches and consultants who sell through calls.
A lead magnet funnel has four moving parts, and once you see them you'll spot this funnel everywhere. First, the magnet, the useful thing you give away. Second, the opt-in page where someone swaps their email for it. Third, the delivery, the email that hands over what you promised. Fourth, the follow-up, the emails that come afterwards and gently move someone toward working with you. That's the whole machine.
The reason it works is that most people who find you aren't ready to buy today, but they might be ready in three weeks. Without a funnel, those people read your post, nod, and vanish, and you've no way to reach them again. The magnet gives them a low-risk reason to raise their hand, and the follow-up gives you permission to keep showing up in their inbox until the timing is right.
The other quiet benefit is that it turns marketing from a series of one-off pushes into something that builds on itself. Every month the magnet keeps collecting emails while you sleep, and every person who opts in stays reachable, so a good month doesn't just end when the month does. You're building an asset that keeps working, not renting attention you have to pay for again next week.
I call it the simplest funnel worth building because you can stand it up with one page, one freebie and a short run of emails. You don't need anything clever. What you do need is to actually build all four parts, and this is where most people fall down.
A good lead magnet solves one specific problem quickly. Not a forty-page ebook nobody finishes, but something a busy person can use in ten minutes and feel a small win from. A checklist, a short template, a two-page guide, a five-minute video that answers one real question. The narrower it is, the better it tends to work.
The other thing that matters is fit. The magnet should attract the people you can actually help and gently repel the ones you can't. If you sell email deliverability audits, a freebie called why your emails land in spam brings you people with exactly that problem. A generic marketing tips freebie brings you everyone, and everyone is nobody. The magnet is doing quiet qualifying work before you ever speak.
If you're stuck for what to make, look at the questions people already ask you before they buy. The thing you find yourself explaining on every first call is usually the perfect magnet, because it's a real problem your ideal client already knows they have. You're not inventing demand, you're packaging an answer you give away anyway.
A quick test: would someone happily pay a small amount for this? If yes, it's probably strong enough to give away. If it feels thin even as a freebie, it'll get the email and then disappoint, and a disappointed subscriber doesn't open the next email. The opt-in page is where this step lives, so it's worth reading what makes a landing page convert alongside this.
Here's the part almost everyone skips. They build a lovely magnet and a decent opt-in page, collect a pile of emails, and then do nothing with them. The freebie gets the email, but it's the follow-up that gets the call. Without it, you've built a list of strangers who took a free thing and forgot you by Thursday.
A follow-up sequence is just a short run of emails, sent over a week or two, and each one has a job:
Four to six emails is plenty to start. The mechanism underneath is trust, built in small deposits. Each email that's genuinely useful makes the next one more likely to be opened, and by the time you ask for the call, you're not a stranger, you're the person who's been quietly helpful in their inbox for a fortnight.
It's also worth checking those emails are actually arriving, because a beautiful sequence that lands in spam books nobody. That's a deliverability question, and it catches more people than you'd expect, especially once you're sending to a few hundred addresses at once.
The invitation itself trips people up, because they either never make it or they make it far too hard. Never asking means the sequence just trails off and the reader never learns you wanted to help further. Asking too hard, with pressure and countdowns, undoes the trust you spent two weeks building.
The version that works is plain. You've been useful, you name the specific problem you help with, and you offer a clear, small next step, usually a short call where you look at their situation together. Describe what the call actually is, so it doesn't feel like a trap. A 15-minute call where we look at where your funnel is leaking is easy to say yes to. Book your strategy session now makes people flinch.
One thing that helps is making the offer feel like a natural continuation of the help you've already given, not a sudden switch into selling. If your emails have been about fixing a leaking funnel, the call is simply the next, more personal version of that. When the invitation matches everything before it, saying yes doesn't feel like a decision, it feels like the obvious next step.
And you can invite more than once. Someone who ignored the invitation in email four might book from email six, because the timing finally lined up. As long as each email is still useful in its own right, a second and third invitation isn't pushy, it's just staying available.
If you're starting from scratch, build it in this order. Pick one specific problem you solve. Make the smallest useful thing that helps with it. Put up a simple page that offers that thing for an email. Then write four to six follow-up emails that help and, near the end, invite a call. That's a complete funnel, and it'll teach you more running than any amount of planning.
Once it's live, watch the two numbers that matter most: how many visitors leave an email, and how many of those eventually book. If the first is low, the magnet or the page needs work. If the first is fine but the second is low, the follow-up is where to spend your attention. You'll know exactly what to fix, which beats guessing.
This is the funnel we build for a lot of clients at Unbury, from the freebie through the emails to the booked call, so if you'd rather have it done with you, a quick audit is a good place to start, or take a look at some of the work first.
The one that solves a single specific problem for the exact person you want to work with. A narrow, genuinely useful thing beats a big impressive one almost every time, because people finish it and feel helped.
Four to six is a good start. Enough to deliver the freebie, be useful a couple of times, show you've helped others, and invite a call once or twice. You can always extend it later once you see what people respond to.
Only if you'll use it. Every extra field lowers the number of people who opt in, so if the email is all you need to follow up, ask for the email and nothing else. Add fields only when they earn their place.
