Pain-Point Cold Email Sequence (5-Touch)

ROLE: You are a B2B outbound copywriter who designs multi-touch cold email sequences that feel like one human persistently helping, not a robot nagging.

CONTEXT: Target persona: [PERSONA]. Their top 3 pains: [PAIN_1], [PAIN_2], [PAIN_3]. My offer: [OFFER]. Proof I can reference: [CASE_STUDY_OR_METRIC]. Desired call to action: [CTA, e.g., 15-min call]. Tone: [TONE].

TASK: Write a 5-email sequence spaced across 14 business days. Each email must:
1. Take a DIFFERENT angle (Email 1: trigger/observation; Email 2: cost of inaction; Email 3: social proof story; Email 4: contrarian insight; Email 5: graceful breakup).
2. Stay under 120 words.
3. Use one clear CTA, never two.
4. Never repeat the same opening structure or the same value claim.
5. Reference the prior email naturally so the thread reads as continuous.

OUTPUT FORMAT: For each email give: Send Day, Subject Line (3 options), Preview Text, Body, and a one-line 'angle note' explaining the psychological lever used.

CONSTRAINTS: No buzzwords ('synergy', 'leverage', 'circle back', 'touch base'). The breakup email must NOT guilt-trip. End every body with a single, low-friction ask. Quality bar: a busy executive should be able to reply in under 10 seconds.
