Email marketing automation - campaign creation, sequence building, A/B testing, deliverability optimization, and analytics

AI-generated overview

Builds email marketing campaigns, automated sequences, A/B tests, segmentation plans and deliverability guidance.

What it does
This skill provides structured templates and frameworks for email marketing work: welcome, newsletter, promotional, cart-abandonment and re-engagement sequences, plus A/B testing plans, list segmentation strategies, deliverability checklists and KPI reporting templates. It produces written campaign plans, sequence outlines, subject-line variants and report formats rather than sending email itself. It is instruction-only and ships no scripts.
When to use it
Use it when planning or drafting email marketing campaigns, drip sequences, subject-line tests, audience segments or deliverability and metrics reviews. It suits marketers and teams working on newsletters, lifecycle flows or promotional sends.
Requirements
No scripts are included; the skill is instructions only. Its metadata references an email MCP server with Mailchimp, SendGrid and Klaviyo tools, so those integrations and their credentials would be needed to actually send or manage campaigns.
