ListFunnel vs. the spreadsheet stack

Enrichment tab, validation tool, analytics export, VLOOKUP glue. It works — that's the trap.

Spreadsheets + point toolsListFunnel
Time to a resolved listAn afternoon of exports, imports, and column-matching — every timeMinutes, repeatably: paste or upload, resolution runs
Engagement joined to identityManual join keyed on email; breaks on every re-exportAutomatic: events land on people continuously
SegmentsFilter views that go stale the moment data changesLiving segments recomputed from rules
CostCheap in dollars, expensive in SundaysFree to start; $49/mo when your list is serious

The honest bit

If you run this analysis once a year on a small list, honestly — a spreadsheet is fine. ListFunnel is for lists you operate, not lists you occasionally glance at.
