The Leaky List
Calculator

You’re sending emails. People are clicking. But if you don’t have follow-up automations in place, every click is a warm lead walking out the door. Put in your numbers. Find out exactly what that silence is costing you every month.

Total subscribers currently on your list

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. We’ll show you what that looks like for your numbers.

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 offer value. Industry data shows click-triggered follow-ups convert at 3–5× that rate — we use 1% deliberately so this number is never inflated. The real figure is likely higher.

Every click deserves a follow-up.
