About
email composer is a davila7/claude-code-templates agent skill for drafting professional emails across business, technical, and customer communication contexts. It asks for purpose, recipient relationship, key points, and desired tone, then outputs a standard structure with a clear subject line, greeting, context opening, body, call to action, and sign-off. The skill supports requests, follow-ups, announcements, and urgent or friendly variants while keeping copy segmentation-friendly for lifecycle and promotional use. Developers reach for email composer when they need help writing stakeholder updates, customer replies, vendor requests, or onboarding sequences—not when implementing SMTP APIs, Resend integrations, or HTML template engines in code. Quick start requires only the communication context; no external tools or dependencies are declared in the manifest.
- Subject lines and preview text
- On-brand tone and CTA placement
- Onboarding and drip sequence copy
- Promotional and announcement templates
- CAN-SPAM-friendly structure cues
