Dynamic Content Personalizer
Takes an already-written email creative plus the segment map (or the raw export columns) and specifies the personalization layer: a merge-tag map where every tag has a stated fallback, conditional-content blocks with per-segment variations, a fallback-safety audit that no empty field or dead conditional can render, and a PII guard on which fields are even allowed into the body. This is the SEND E (Engagement/personalization) lever. It does not build segments, write the base copy, or score the program.
Scope guard: this skill wires personalization onto existing copy for existing segments only. It does not define WHO the segments are (list-segment-builder), does not write the subject/body/CTA (email-creative-builder), and does not score, roll up the EQS, or run the S1/S2/N1/D1 vetoes (email-quality-auditor owns those).
Quick Start
Add merge tags with fallbacks to this email [paste creative]; export columns are first_name, city, last_product. Promo mode.
Set up conditional blocks: champions get the loyalty offer, at-risk get the win-back offer, everyone else the base offer. Segment map attached.
Audit this template for fallback safety and PII exposure before we send. [paste template with {{merge_tags}}]
