Optimize Email Performance & Deliverability

Analyzes your actual email send history to find subject-line patterns that work for your list, audits compliance and rendering issues, identifies revenue-generating segments, and automates re-engagement for dormant subscribers. Most email teams operate blind on what actually lifts opens and clicks for their specific audience.

1. Connect your ESP (Klaviyo, Mailchimp, Rule, Get a Newsletter) via Cogny. 2. Run /subject-line-lab to mine your last 100+ sends, extract winning patterns (length, punctuation, emojis, urgency words, timing), and compare against baseline. 3. Generate 20 tuned subject-line candidates for your next campaign using those patterns. 4. Run /pre-send-qa to audit merge tag fallbacks, broken links, spam triggers, and CAN-SPAM compliance before sending. 5. Use /welcome-series to generate a full 5-email onboarding sequence from a brand URL. 6. Run /revenue-audit weekly to find missing flows, dormant high-value subscribers, and under-segmented campaigns. Output: subject-line pattern reports with top winners/drags, QA checklists, and revenue-impact recommendations.

Free reference: /welcome-series generates sequence from brand URL. Premium skills require Cogny MCP plus connected ESP (Klaviyo, Mailchimp, Rule, Get a Newsletter). Subject Line Lab requires 30+ historical sends in ESP for reliable pattern detection. Apple Mail Privacy Protection inflates open rates; skills use CTR as secondary metric.
