The Scorecard
- Campaign copywritingClaude
Subject, preview, hero, body, CTA — written from a strategist brief in your voice guide, with two variants per send.
- Flow copy (welcome, abandoned, winback)
Multi-step flow copy with purposeful pacing, incentive logic, and clear merge tags that don't break on send.
- Brand-voice adherenceClaude
Every draft passes a voice-match review against your style guide before human QA.
- Subject-line testing
Variants built for meaningful A/B comparisons with sample-size and significance awareness.
- Plain-English reporting
What copy changes moved the metric, in a short memo — not a spreadsheet dump.
AI Stack They're Certified On
Sample KPIs
- Sends shipped / week (target ≥ 3 with 2+ copy variants)
- Revenue per recipient lift vs control (target ≥ 10%)
- First-pass QA acceptance (target ≥ 90%)
- Voice-guide compliance score (target ≥ 95%)
Drafts subject-line variants, first-pass body copy, and runs brand-voice audits against your style guide.
Rewrites every AI draft line-by-line, owns brand voice, and signs off on copy before QA.
Sample SOP
- Brief — strategist drops audience, offer, KPI, and voice cues.
- AI first draft — operator prompts Claude with the brief + voice guide.
- Human rewrite — never ship the AI draft raw. Operator edits line-by-line.
- Voice-match check — second operator runs a voice audit before QA.
- QA + send — handed to Klaviyo Ops for build + QA.
Rule: AI speeds drafting, not shipping. Every line gets a human.
Who this operator is for
Your retention strategist is writing every line of every email. They shouldn't be. A StackCertified Email Copywriter drafts first copy, runs the AI voice pass, and hands clean drafts to Klaviyo Ops — so strategists review, not write.
What changes in the first 30 days
- Week 1 — shadow voice, build prompt library for your brand.
- Week 2 — draft two campaigns with heavy strategist review.
- Week 3 — own flow-copy rewrites end-to-end.
- Week 4 — strategist reviews briefs in minutes, not Fridays.
What they don't do
They don't set strategy or decide offers. They write the voice.
