AI Email Production System for a Marketing Agency

2024-11-01

Structured AI workflow for writing, reviewing, and managing campaigns at agency scale.

Built a complete AI-powered email production system for agency use: prompt library, campaign SOPs, brand voice rules, writing workflows, and review logic. Every campaign follows the same structured process.

The challenge

Writing email campaigns for multiple clients at an agency level means constantly context-switching between brand voices, offer structures, and content rules. Without a system, quality is inconsistent and production is slow. The goal was to standardize the entire workflow so AI could produce on-brand, high-quality campaign drafts with minimal correction needed.

Approach

• Built a structured prompt library covering every campaign type: welcome, promo, launch, re-engagement, seasonal
• Created brand voice profiles for each client: tone, forbidden phrases, offer framing rules
• Developed a two-phase writing workflow: hook refinement first, then full email. Reducing revision cycles.
• Wrote SOPs for each step of the campaign process: brief intake, first draft, review, final send
• Integrated strategy logic: campaign objective determines subject line angle, hook type, and CTA structure
• System produces ready-to-send drafts that require review, not rewriting

Results

• 3× — faster campaign production vs. manual writing
• 100% — structured workflow. Brief in, draft out.
• Multi-client — brand voices maintained consistently
• 0 — campaigns written from blank page
