Add Email Marketing Strategist

[hedonnn]

What does this PR do?

Adds a new Email Marketing Strategist agent to marketing/ — a CRM-driven email architect who designs segmentation schemas, lifecycle automation sequences, and deliverability frameworks grounded in 2025-2026 benchmarks and post-Apple Mail Privacy Protection measurement.

This agent doesn't write email copy — it architects the system that delivers the right copy to the right person at the right time. It thinks in segments, lifecycle states, and exit conditions, not subject lines and hero images.

Agent Information

• Agent Name: Email Marketing Strategist
• Category: marketing
• Specialty: CRM-driven campaigns, lifecycle automation, segmentation architecture, deliverability, and post-Apple MPP measurement

What makes this agent different

Most email agents focus on copywriting. This one focuses on the engineering behind effective email programs:

1. Segmentation-first approach — every campaign targets a specific segment defined by at least two attributes. Broadcast sends are explicitly forbidden.
2. Complete sequence design documents — with trigger events, timing tables, A/B variants, exit conditions, and benchmark targets per email
3. CRM-to-ESP attribute mapping — concrete templates for syncing data between CRM systems and email platforms, with field types, sync methods, and edge case handling
4. Deliverability audit checklists — SPF/DKIM/DMARC verification, complaint rate monitoring, list hygiene protocols, aligned with Google/Yahoo/Microsoft 2024-2025 enforcement changes
5. Post-Apple MPP metrics — treats open rates as directional only, builds dashboards around CTR, CTOR, and conversion rate

The agent includes specific benchmark tables (email-level and system-level) with Good/Great/Alert thresholds, and covers advanced capabilities including AI-powered send-time optimization, behavioral trigger architecture, and multi-language campaign design.

Motivation

Email marketing remains one of the highest-ROI channels, but most teams operate with weak segmentation, no exit conditions, and metrics built on inflated open rates. The gap between "we send emails" and "we have a segmented lifecycle automation system" is where this agent lives.

This is especially valuable for lead-gen and service businesses where the sales cycle is long, the CRM is the backbone, and lifecycle email sequences (welcome through referral) directly drive pipeline.

Testing

Tested on real estate lead-gen, SaaS onboarding, and local service business scenarios with Brevo, MailerLite, and ActiveCampaign. The sequence design document format consistently produces more complete automation builds than ad-hoc email planning. The deliverability checklist has caught real authentication issues in testing.

Checklist

• Follows agent template structure from CONTRIBUTING.md
• Includes YAML frontmatter with name, description, color, emoji, vibe
• Has concrete template examples (Sequence Design, Attribute Map, Deliverability Audit)
• Includes personality and voice (data-driven, benchmark-quoting, segment-first)
• Defines success metrics (email-level, system-level, and revenue metrics with specific thresholds)
• Includes step-by-step workflow (6 phases: Audit → Architect → Build → Test → Launch → Optimize)
• Proofread and formatted correctly
• Tested in real scenarios
