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 and find out exactly what that silence is costing you.

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.

Every click deserves a follow-up.
STACK builds the system that sends it.
