Email Compose System Architecture

How fixed, dynamic, and strategic inputs triangulate to produce an email

Fixed — The Numerator
Who Stratum Is
Mission & thesis
Positioning language (Phrase Registry)
Credentials & proof points
Values (transparency, provider-first)
Same across all emails. Slow-changing.
Dynamic — The Denominator
Who They Are
POI Brief (facility, payers, pain)
Role (CFO, RCM Dir, Clinician...)
Facility context (size, state, lines)
SILy signals (what's happening to them)
Unique per lead. From research.
Strategic — The Variables
How We Approach
Track — why this person type
Signal — what makes it timely
Cadence — where in the arc
Per-email compositional choices.
Composed Email
AIDA arc shaped by all three

Pressure Testing the Variables

TRACK
Why are we reaching this person?
Provider — sell to them
Research — partner with them
Advocate — ally/amplify through them
✓ Clean, stable. Three distinct relationship types.
SIGNAL
What external force creates urgency?
CRISIS — fire burning now
CEILING — money left on table
WINDOW — time-limited opportunity
SIZING — not a signal?
⚠ SIZING is a quantifier, not a force. It belongs in the POI brief, not as a signal. Reduces to 3 signals.
CADENCE
Where in the relationship arc?
First Touch — cold intro
Follow-up — new angle
Close — direct ask
⚡ Is 3 emails the right drip? Current Day 1/4/7/10/14/21 — but structure only changes at 3 breakpoints.

The Reframe

Old System (Template DB)
83 pre-written emails
Claude fills in [brackets]
Template = the email
Stratum's identity embedded per-template
Signal, role, cadence all baked into copy
New System (Prompt-First)
9 few-shot examples (3 track × 3 signal)
Claude composes from scratch
Prompt = Stratum's identity (fixed)
POI brief = their world (dynamic)
Track + Signal + Cadence = metadata inputs

Open Questions

1. Should SIZING become a POI brief field instead of a signal?
2. Is 3 emails the right drip length? Or should cadence be engagement-adaptive?
3. What fixed Stratum content goes into the prompt? Just phrase registry + positioning, or also credentials/proof points?
4. Do the 9 few-shot examples cover Track × Signal, with cadence as metadata? (Signal shapes AIDA arc, so it's structural)
