Chat on WhatsApp →What is a lead magnet?
A lead magnet is a free, useful resource, such as a checklist, guide, template or calculator, that a business offers in exchange for contact details. Promoted on social media, it builds a list of interested buyers you can follow up with, rather than relying on cold enquiries.
How much does a lead magnet campaign cost?
Writing and designing a short guide or checklist, plus its landing page and three ads, takes 10 to 20 hours, an indicative £750–£2,000. Running the ads sits in the paid social band of £300–£1,000 a month. A three-email follow-up sequence adds 3 to 6 hours, about £225–£600.
- Guide, landing page and ads: £750–£2,000.
- Follow-up emails: £225–£600, indicative.
- Monthly ads management: £300–£1,000.
- Media spend: paid to the platform on top.

Chat on WhatsApp →How do you judge a lead magnet campaign?
Track three numbers: cost per download, the share of downloads that become conversations, and the cost of each customer won. A cheap download that never turns into a conversation is not a bargain. Give follow-up at least six to eight weeks before judging.
When is a lead magnet the wrong approach?
If buyers need you urgently, such as an emergency trade, a direct call to action beats a download. If you have no time to follow up, downloads sit unused. And a generic guide anyone could write attracts researchers, not buyers.
What does this look like in practice?
A pattern we see: a firm offers a broad industry guide and gets cheap downloads but no enquiries. A narrower checklist tied to the moment before buying, such as preparing for a quote, usually attracts fewer but far better leads.
Lead magnet checklist
- Solve one problem buyers have just before buying.
- Keep it short enough to finish in ten minutes.
- Build a landing page with a clear consent line.
- Write the follow-up emails before launch.
- Measure cost per conversation, not per download.

Frequently asked questions
How much does it cost to create a lead magnet?
A short guide, checklist or template with its landing page and ads costs an indicative £750–£2,000 at UK agency rates. Calculators or tools that need building cost more. Follow-up emails add about £225–£600.
Are lead magnets still effective?
Yes, when they solve a specific problem buyers have close to purchase. Broad guides attract researchers who rarely buy. A focused checklist or calculator usually produces fewer, better leads.
Can I email people who download my guide?
You can send what they asked for. For ongoing marketing emails to individuals, PECR generally requires consent, so add a clear opt-in on the form. Business contacts at companies are treated differently; check ICO guidance.
