Build Better Email Sequences with the emails Skill

Where this fits

You just added a free trial to your SaaS and realized the signup confirmation is a one-off email with no follow-through. You need a sequence that welcomes, activates, and converts — without building it from scratch. The emails skill helps agents design structured multi-email flows: drip campaigns, onboarding programs, re-engagement series, and lifecycle automation.

Why agents benefit

• Automatically checks for .agents/product-marketing.md (or legacy context files) before asking questions, so it reuses existing knowledge.
• Asks only for the gaps: audience, goal, cadence, tone, and desired action.
• Produces a complete sequence with each email's trigger, delay, purpose, subject line, and body.
• Distinguishes between email sequences, cold outreach, and in-app onboarding, so the right format is used.
• Optimizes existing flows by clarifying conversion points and removing friction.

Practical scenarios

New user onboarding flow

A product team wants to move new signups to their first key action. The agent reads the product marketing context, then designs a five-email welcome series: confirmation, setup tips, first-value case study, feature spotlight, and an invitation to talk to support.

Re-engagement for dormant accounts

A subscription business has users who stopped logging in after 30 days. The skill guides the agent to build a pause-based re-engagement sequence with a feedback loop, a helpful resources email, and a final “we’ll keep your account safe” message that reduces churn.

Feature adoption lifecycle

A company launches a new reporting feature. The agent uses the skill to create a trigger-based lifecycle flow that introduces the feature to active users, explains advanced use cases, and encourages upgrading the plan — all while respecting existing email frequency.

Add it to your agent workflow

Install the skill with:

npx skills add coreyhaines31/marketingskills --skill emails

Then ask your agent to “use the emails skill to create a five-email onboarding sequence for new workspace signups, reading the product-marketing context first.” The agent will gather remaining requirements and output a ready-to-review email program.

Compare before adopting

Look at how this skill compares to generic prompt-based email design, other marketing skills in the same repository, and in-house email templates. Check quality signals like README depth, version history (current: 2.0.0), and whether the author maintains related skills. Also consider workflow fit: does your project already keep product-marketing.md context files? If not, you may need to add that content to get the full benefit.

Why it is worth tracking

With 46,637 stars, the emails skill has real community momentum. It is worth tracking because email sequence design is a recurring task across SaaS, ecommerce, and content products, and this skill gives agents a structured starting point that can be versioned and improved. Evaluate it now, and watch for future updates around A/B testing or deliverability checks that would make it even more valuable.
