The Leaky List
Calculator

You built the lead magnet. You grew the list. People are clicking your emails. But without a system that responds to what they actually do, every click is a buyer signal disappearing into silence. Put in your numbers and find out exactly what that’s costing you every month.

List size

Total subscribers on your list — include your full list, not just buyers

Please enter your list size

How many times do you email your list per month?

The number of separate emails each subscriber receives from you — e.g. if you send weekly, enter 4. Recommended: 8–12 sends per month. More sends = more clicks = more opportunities to convert.

How we calculated this

Your clicks per month = list size × click rate × emails per month. We assume 100% of those clicks currently get no automated follow-up. Missed revenue uses a conservative 1% conversion rate on unworked clicks × your product price. Industry data shows click-triggered follow-ups convert at 3–5× that rate — we use 1% deliberately so this number is never inflated.

Every click is a buyer signal.
