Email Composer

The Email Composer skill helps you craft professional, effective emails for any business context. Whether you need to reach out to a client, respond to a team inquiry, follow up on a meeting, or send a cold outreach message, this skill ensures your emails are clear, appropriately toned, and action-oriented.

This skill analyzes the context you provide and generates emails that match the appropriate level of formality, include necessary components (subject line, greeting, body, call-to-action, closing), and maintain professional standards. It can adapt tone from casual internal communications to formal external correspondence.

The skill also considers email best practices like brevity, clarity, scannable structure, and clear next steps to maximize response rates and effectiveness.

Tone Guidelines

Context Tone Example Opening
Cold Outreach Professional, Value-focused "I noticed your work on [X] and wanted to reach out..."
Internal Team Casual, Clear "Quick update on the project..."
Client Communication Professional, Helpful "Thank you for your message regarding..."
Executive Communication Formal, Concise "Per our discussion on [topic]..."
Follow-up Friendly, Persistent "I wanted to circle back on..."
Apology Humble, Solution-oriented "I apologize for the confusion regarding..."

Common Pitfalls to Avoid

  • Too Long: Emails over 300 words rarely get fully read
  • Buried Lede: Put the main point in the first paragraph
  • No Clear Ask: Always end with what you need from recipient
  • Generic Greetings: Personalize when possible
  • Over-Apologizing: One sincere apology is enough
  • Reply-All Abuse: Only use when truly necessary
  • Vague Subject: Be specific about email content
  • Missing Context: Don't assume recipient remembers previous conversations
