The problem
I’ve signed up for enough lists to know the letdown of a generic follow-up. Building my own list, I didn’t want to be that sender. But hand-picking a response for every submission doesn’t scale past a handful a day.

The approach
A single waterfall classification, running in Make.com, sorts each submission into one of five segments the instant someone hits submit.
How it works
- Six boolean signals feed a priority-ordered waterfall; first match wins
- The subscriber record is created and fully populated before any group assignment
- So even a misfiring step never loses the lead’s data
- Each of the five outcomes maps to its own email track

Design decisions
- Priority ordering is the actual logic: the override check runs before the pattern checks, or someone stuck the longest falls into a weaker bucket
- Store-first, route-second means the system fails safe, not silently
- Shipped with one crafted test submission per classification, verified end-to-end

What this demonstrates
Rules-based classification and reliable routing in a no-code environment: the same decomposition, priority logic, and testing a scripted integration needs, on a platform a non-engineering team can maintain.
