Email Sending Best Practices

This skill helps review and plan healthy email programs. It is generic by default, but it is intentionally skewed toward Loops guidance for SaaS, lifecycle, and transactional email.

When To Use

Use this skill when the task is about email quality, risk, or strategy rather than low-level API implementation.

Typical use cases:

• diagnose poor inbox placement or sender reputation
• review consent flows, double opt-in, list hygiene, or unsubscribe behavior
• improve subject lines, preview text, sender identity, personalization, or rendering
• choose between campaign, lifecycle automation, and transactional email
• plan onboarding, retention, re-engagement, dunning, or product-update email programs
• review a Loops setup for best-practice gaps

Do not default to this skill for pure implementation tasks like "send an event with the Loops API" or "wire up transactional email in Next.js". Use the loops-api skill for those.
