email-lifecycle-marketing_skill

Overview

This skill helps founders design high-ROI email lifecycle programs for SaaS products, from welcome sequences to retention and upgrade flows. It packages proven templates, timing, triggers, and subject-line formulas so you can launch effective campaigns that drive activation, retention, and revenue. Use it to convert trials, reduce churn, and increase product engagement with behavioral, not just time-based, emails.

How this skill works

The skill maps lifecycle stages to behavioral triggers, then generates full emails (subject, preview text, HTML/plain body, CTA) and a send schedule. It includes subject-line formulas, deliverability and technical checks, and recommended metrics to track for each campaign. Outputs are ready to copy into your ESP and include plain-text fallbacks and conditions for sending.

When to use it

• Designing a welcome/onboarding drip for new signups
• Building trial-to-paid conversion flows and expiry reminders
• Creating behavioral activation nudges for key product actions
• Setting up retention and re-engagement campaigns for inactive users
• Crafting upgrade or expansion emails tied to usage milestones

Best practices

• Make every email answer: 'Why should I care about this right now?'
• Prefer behavioral triggers over fixed time delays whenever possible
• One email = one goal = one clear CTA; avoid multiple CTAs
• Keep subject lines <50 chars, personalize, and A/B test when volume allows
• Ensure SPF/DKIM/DMARC, list hygiene, and plain-text fallbacks for deliverability

Example use cases

• Welcome sequence that drives the single activation step within the first week
• Trial expiry series that reminds, warns, and recovers churned trials
• Activation nudge when a user signs up but never completes onboarding
• Re-engagement drip for users inactive 14+ days highlighting recent improvements
• Usage-based upgrade prompt when a user hits 80% of a quota
