the launch film — addresses in, people out.
How it works
A marketing list is just addresses. Yours doesn’t have to be.
Bring any list
Newsletter export, CRM dump, waitlist, customer file. Paste it or upload a CSV — ListFunnel extracts and dedupes every address.
Resolve and score
Every address becomes a person — name, title, company, industry. Then behaviour lands on top: who reads, who buys, how much, how often.
Segment and grow
Audiences form from what's actually working. Find more people like your best readers and invite them in. Keep the list clean while you do it.
Why it matters
Open rates tell you almost nothing. People tell you everything.
Every send tool shows you the same three numbers. None of them tell you who — who your best readers are, what they do for work, which content pulled them in, and which of them actually pay you. ListFunnel starts where send tools stop: at the identity behind the address.
- Resolve the person behind every address
- See reads, buys, spend, and frequency per person
- Watch your audience shift when your content shifts
- Grow from your best readers, not cold lists
