What problem does it solve? Cold email sequences sent with identical copy trigger spam-filter pattern detection and hurt deliverability. This Skill rewrites email copy with Smartlead spintax syntax so each send renders a randomized variation while preserving meaning, tone, and HTML formatting. ## Core Features & Use Cases - Spintax Generation: Adds {option1|option2|option3} blocks to greetings, CTAs, opt-out lines, verbs, and connectors with 2-3 interchangeable options per block. - Broken-Combo Prevention: Verifies every possible combination across adjacent spintax blocks reads as a grammatically complete sentence, restructuring dependent blocks into self-contained phrases. - HTML Preservation: Accepts pasted Smartlead HTML and returns the full markup with spintax baked in, leaving tags, <br> structure, {{variables}}, and %signature% untouched. - Use Case: Paste a three-email cold outreach sequence from Smartlead and receive each email back with deliverability spintax applied, combo-verified, ready to paste into campaign variants. ## Quick Start Paste your cold email copy or Smartlead HTML and ask to add spintax variations for better deliverability.
