📧 Email Writing Coach

Here’s the future of email writing education: your draft email + AI analysis = professional writing mastery.

Struggling with pitch emails that don’t get responses? Don’t rely on AI to write for you. Build a coach that analyzes your writing, highlights specific problems, and teaches you how to improve your professional communication skills through targeted feedback.

This lesson teaches you: How to create educational AI applications that coach users instead of doing the work for them. You’ll build an email writing coach that rivals expensive writing training programs.

Building on: This transforms your AI foundation into an educational tool with analysis capabilities, visual feedback, and character limit management.

🎯 From Auto-Writing to Writing Education

Here’s what traditional email tools do wrong:

❌ Write emails for you instead of teaching you
❌ Don't explain why changes are needed
❌ No learning happens - you stay dependent
❌ Generic feedback that doesn't improve skills
❌ No character limits to encourage concise writing

Here’s what our Email Writing Coach delivers:

✅ Analyzes YOUR email draft and highlights specific issues
✅ Explains WHY something needs improvement
✅ Teaches professional writing principles through feedback
✅ Character limits (800/1500) encourage concise communication
✅ Never corrects for you - helps you learn to improve

Watch this transformation:

Traditional approach: “AI, write my email” → AI writes email → You learn nothing

Our approach: You write email → AI analyzes and highlights problems → Explains issues → Suggests improvements → You rewrite and learn

The result: You become a better email writer through AI-powered coaching, not AI dependency.

🛠️ Step 1: Build Your Email Analysis API (Backend Coach)

We’ll create a specialized endpoint that analyzes email drafts, highlights issues, and provides educational feedback without ever correcting the email for the user.

Add this email coaching endpoint to your index.js:

// 📧 EMAIL WRITING ASSISTANT: Highlights and marks errors like a teacher grading papers
app.post("/api/email-coach", async (req, res) => {
  try {
    const {
      emailDraft,
      emailType = 'pitch',
      targetAudience = 'professional'
    } = req.body;

    if (!emailDraft) {
      return res.status(400).json({ error: "Email draft is required" });
    }

    const emailEditor = `You are Professor Elena Rodriguez, a professional writing instructor who marks up student emails like a teacher grading papers. You highlight specific text sections that need improvement and provide clear feedback notes.

YOUR MISSION: Mark up the email draft by identifying specific text sections that have issues and provide helpful feedback notes for each marked section, just like a teacher would do with a red pen.

YOUR MARKING APPROACH:
- Identify specific phrases, sentences, or words that need improvement
- Mark different types of issues (tone, clarity, structure, professionalism)
- Provide clear, constructive feedback for each marked section
- Explain WHY each marked section is problematic
- Suggest HOW to improve each marked section
- Focus on teaching better writing habits

EMAIL CONTEXT:
- Email Type: ${emailType}
- Target Audience: ${targetAudience}
- Character Count: ${emailDraft.length}

EMAIL DRAFT TO MARK UP:
"${emailDraft}"

RESPONSE FORMAT (JSON only):
{
  "originalText": "${emailDraft.replace(/"/g, '\\"')}",
  "wordCount": ${emailDraft.split(' ').length},
  "characterCount": ${emailDraft.length},
  "markedSections": [
    {
      "id": "mark_1",
      "startIndex": 0,
      "endIndex": 10,
      "markedText": "exact text that needs improvement",
      "issueType": "tone|clarity|structure|grammar|professionalism|wordiness",
      "severity": "major|minor",
      "feedback": "Clear explanation of what's wrong with this section",
      "suggestion": "Specific advice on how to improve this section",
      "color": "red|orange|yellow"
    }
  ],
  "overallFeedback": {
    "strengths": ["What's working well in this email"],
    "mainIssues": ["Primary problems to address"],
    "improvementPriority": "Focus on [specific area] first, then address [other areas]"
  },
  "writingTips": [
    "Professional writing tip based on the issues found"
  ]
}

MARKING GUIDELINES:
- Mark specific text sections that have clear issues
- Use different colors: red (major issues), orange (moderate), yellow (minor)
- Provide actionable feedback for each marked section
- Focus on 3-8 key issues rather than marking everything
- Be encouraging while being honest about problems
- Teach writing principles through your feedback
- Return only valid JSON with proper escaping`;

    console.log(`📧 Professor Rodriguez is analyzing your email...`);

    const response = await openai.chat.completions.create({
      model: "gpt-4o-mini",
      messages: [{ role: "user", content: emailEditor }],
      temperature: 0.3
    });

    const markupJson = response.choices[0].message.content;
    const markup = JSON.parse(markupJson);

    res.json({ success: true, markup });

  } catch (error) {
    console.error("Email coaching error:", error);
    res.status(500).json({ error: "Failed to analyze email" });
  }
});

See what just happened?

You defined an email coach - Professor Elena Rodriguez with teaching expertise
Analysis-focused approach - Highlights problems and explains WHY they’re issues
Character limit enforcement - 800/1500 character limits for concise writing
Educational feedback - Teaches writing principles instead of doing the work
Structured JSON response - Consistent data format for highlighting and feedback

This is your email education challenge becoming an intelligent coach. No rewriting - just analysis, highlighting, and teaching that improves writing skills.

📱 Step 2: Build Your Email Writing Coach Interface (Frontend Education)

Now we’ll create an educational email coaching app with character limits, text highlighting, and detailed feedback - focused on teaching rather than writing.

Save your existing apps, then create the new coach:

2A: Preserve Your Current Work

# Save your current work
cp src/App.jsx src/PreviousApp.jsx

2B: Create Your Email Writing Coach App

Replace your src/App.jsx with this educational email coaching experience:

📋 Professional Writing Focus

Email context awareness - Understands different email types and audiences
Professional writing standards - Focuses on business communication effectiveness
Constructive criticism - Points out problems while teaching writing principles
Visual learning - See exactly where issues occur in your text

🧪 Step 3: Test Your Email Writing Assistant

Let’s see how your markup system highlights and provides feedback like a teacher grading papers:

Start your servers:

Backend:

cd openai-backend
npm run dev

Frontend:

cd openai-frontend
npm run dev

Test the teacher-style markup:

Phase 1: Experience the Markup Interface

1. Visit http://localhost:5173
   • See the Email Writing Assistant with blue/slate teacher theme
   • Notice the simplified configuration: email type and audience only
   • Focus on text markup and feedback rather than scoring
   • Character and word count tracking in real-time

Phase 2: Test Email Markup with Poor Writing

2. Mark up a poorly written pitch email:
   • Email Type: "Pitch Email"
   • Audience: "Executive/Leadership"

   Paste this problematic email:
   "hey there!!! hope ur having a great day :) i wanted to reach out because i think our company could really help you guys out with your marketing stuff. we're super good at what we do and have helped tons of companies before. let me know if you want to chat sometime! thanks!!!"

   Professor Elena's Markup:
   • Red highlights: "hey there!!!", "ur", "you guys", "stuff"
   • Orange highlights: "super good", "tons of companies"
   • Yellow highlights: ":)", "chat sometime"
   • Click each highlight to see specific feedback
   • Overall feedback shows main issues and strengths
   • Writing tips based on identified problems

Phase 3: Test Interactive Feedback System

3. Click on highlighted sections to see detailed feedback:
   • Click "hey there!!!" → See tone feedback and professionalism suggestions
   • Click "ur" → See grammar/spelling feedback
   • Click "you guys" → See audience-appropriate language feedback
   • Click "stuff" → See clarity and specificity feedback
   • Each click shows: What's wrong + How to improve it
   • Close feedback panel and try clicking other highlights

Phase 4: Test Different Email Types

4. Try marking up a request email:
   • Email Type: "Request Email"
   • Audience: "Professional Contact"

   Paste this email:
   "Dear Sir/Madam, I hope this email finds you well. I am writing to you today to request your assistance with a matter that has come to my attention. Our team has been working on a project for several months now, and we have encountered some challenges that require additional resources. I would be grateful if you could consider providing us with the necessary support to complete this important initiative."

   Professor Elena's Markup:
   • Orange highlights: "Dear Sir/Madam", "I hope this email finds you well"
   • Yellow highlights: "a matter that has come to my attention", "additional resources"
   • Feedback focuses on being more specific and direct
   • Shows word count (67 words) and suggests more concise approach

What to notice:

Visual markup system - Text is highlighted like a teacher’s red pen
Clickable feedback - Each marked section provides specific guidance
Color-coded severity - Red, orange, yellow indicate problem severity
No scoring system - Pure focus on constructive feedback
Interactive learning - Click and learn from each marked section
Teacher-student relationship - Professor Elena provides patient, educational feedback

🔧 Common Issues & Solutions

❌ “Text highlighting doesn’t appear or looks broken”

✅ Confirm your backend /api/email-coach endpoint is running on port 8000
✅ Check that backend returns markedSections array with startIndex and endIndex
✅ Verify renderMarkedupText() function is properly sorting marked sections

❌ “Clicked highlights don’t show feedback panels”

✅ Check that selectedMark state is being set when clicking highlighted text
✅ Verify each marked section has feedback and suggestion properties
✅ Ensure the feedback panel conditionally renders when selectedMark exists

❌ “Markup colors don’t match severity levels”

✅ Confirm backend returns color property as ‘red’, ‘orange’, or ‘yellow’
✅ Check that CSS classes for each color are properly defined
✅ Verify the color logic in renderMarkedupText() function

❌ “Word/character counts are incorrect”

✅ Check that backend calculates wordCount and characterCount correctly
✅ Verify frontend displays the counts from the markup response
✅ Ensure the display logic handles cases where markup might be null
