What it does
Execute cold email outreach with pre-flight checks and segment-specific sequencing
Best for
B2B sales teams when you need a gated cold email execution process that validates positioning and offer BEFORE sequence creation, using buyer verbatims.
Inputs
- · F1 positioning (ICP + pain + trigger defined)
- · F2 offer (outcome statement + proof point)
- · Prospect list filtered by segment rules
- · Buyer verbatims from JTBD research
Outputs
- · 3-touch email sequence
- · Segment filter criteria
- · Verified prospect list (bounce <3%)
- · Email subject lines and body copy
Requires
- · Email platform with deliverability infrastructure
- · List verification tool (Apollo, Hunter.io, etc.)
- · JTBD and competitive intelligence research prompts
Preconditions
- · F1 positioning fully complete
- · F2 offer with outcome statement and proof point
- · Sending domain SPF/DKIM/DMARC configured
- · Warmup tool running
Failure modes
- · Skipping F1/F2 validation, leading to poor conversion
- · List unverified, bounces destroy sender reputation
- · Segment filter too broad, targeting wrong buyer
- · Sequence CTA unclear or requires too much friction
Trust signals
- · 6-step pre-flight check (F1 complete?, F2 complete?, Stranger Test, List exists, Sending infrastructure, Archetype confirmation) that gates execution
- · Step 1 mandates buyer JTBD and competitive intelligence research first
- · Step 2 defines segment filter with 5 concrete criteria (Industry, Revenue, Headcount, Geography, Trigger)
- · Step 3 produces 3-touch sequence using buyer verbatims (not vendor language)
- · Segment-specific routing (startup archetypes vs service firms vs trade businesses)
