Setup Process

First Run

When a user requests email marketing help for the first time, initiate the setup wizard:

1. Check for credentials

   javascript

   const credsPath = '/data/.openclaw/workspace/.kit-credentials';
   

   If missing, run setup.

2. Setup wizard flow

   • Welcome and explain what you'll collect
   • Request Kit API credentials (v4 key + secret)
   • Store encrypted using scripts/credentials.js
   • Optional: voice training (analyze 3-5 past emails)
   • Optional: database integration (point to voice guide files)
   • Collect business context (niche, audience, offers, links)
   • Fetch Kit custom fields for future personalization
   • Confirm setup complete

3. Voice training (if provided)

   • Analyze provided email samples
   • Extract: tone, structure, vocabulary, sentence patterns
   • Save voice profile to /data/.openclaw/workspace/.kit-voice-profile.json
   • Use this profile for all future email generation

4. Database integration (if configured)

   • Ask for path to voice guide (e.g., content/writing-rules/VOICE-GUIDE.md)
   • Ask for path to memory files (e.g., MEMORY.md)
   • Store paths in credentials file
   • Read these before generating emails

Email Generation Workflow

Step 1: Clarifying Questions

Before writing any email, ask these questions:

Required:

• Goal: What's the purpose? (nurture/sell/announce/educate/re-engage/onboard)
• Audience: Who's receiving this? (all subscribers/specific tag/specific segment)
• Main message: What's the core point you want to communicate?
• Call to action: What should readers do? (click link/reply/take action)

Optional:

• Links to include: Any specific URLs to feature?
• Tone preference: (if not using voice training)
• Personalization: Should we use first name? Custom fields?
• Timing: Send now, schedule, or save as draft?

Example questioning flow:

text

I can help you write that email. A few quick questions:

1. What's the goal? (nurture relationship / make a sale / announce something / educate)
2. Who's this going to? (all subscribers / a specific tag / a segment)
3. What's the main message or value you want to communicate?
4. What action should they take after reading?
5. Any links you want me to include?
6. Should I personalize with first names?

Step 2: Generate Content

Subject Lines (provide 3 options):

• Use formulas from references/subject-line-formulas.md
• Keep 27-73 characters
• Tap into curiosity, urgency, benefit, or social proof
• Avoid spam triggers (all caps, excessive punctuation)

Preview Text:

• 40-70 characters
• Complements subject line
• Teases value inside

Email Body:

• Follow structure from references/email-best-practices.md
• Match user's voice (if trained) or requested tone
• Include personalization tags if requested
• Strong hook in first sentence
• Clear value proposition
• Natural CTA placement
• Keep scannable (short paragraphs, white space)

Personalization Tags: Reference references/kit-personalization.md for available tags:

• {{ subscriber.first_name }} - Subscriber's first name
• {{ subscriber.email_address }} - Email address
• Custom fields: {{ subscriber.YOUR_FIELD_NAME }}

Example generation output:

markdown

## Subject Line Options

1. [Name], here's what 80% of email marketers get wrong
2. The 3-minute email hack that doubled my opens
3. Your subscribers are telling you something (listen closely)

## Preview Text

Most people ignore this signal. Here's how to spot it.

## Email Body

Hey {{ subscriber.first_name }},

Quick question: when was the last time you checked your email open rates?

[rest of email...]

**Call to Action:**
[Read the full guide here →](https://example.com/guide)

Talk soon,
[Your Name]

Step 3: Review & Refine

Present the email to the user and ask:

• "How does this sound?"
• "Want me to adjust the tone?"
• "Should I try a different angle?"
• "Ready to send, or should we save as draft?"

Make revisions based on feedback.

Step 4: Send via Kit API

Once approved, use scripts/kit-api.js to:

Create broadcast:

javascript

const { KitAPI } = require('./scripts/kit-api.js');
const kit = new KitAPI();

const broadcast = await kit.createBroadcast({
  subject: "Chosen subject line",
  content: "Email HTML content",
  description: "Internal description",
  send_at: "2026-02-17T10:00:00Z", // or null for draft
  public: false,
  tag_ids: [123, 456] // if targeting specific tags
});

Options:

• Draft: send_at: null - save for review later
• Schedule: send_at: "ISO timestamp" - schedule for future
• Send now: Don't include send_at (immediately publishes)

Targeting:

• All subscribers: Don't include tag_ids or segment_ids
• Specific tags: tag_ids: [123, 456]
• Specific segments: segment_ids: [789]

Confirm with user before sending.

Campaign Management

View Campaign Stats

After sending, users can request performance data:

javascript

const stats = await kit.getBroadcastStats(broadcastId);

Present stats in readable format:

Example Workflows

Workflow 1: Welcome Email

User: "Write a welcome email for new subscribers"

You:

text

I can help you write that welcome email. A few quick questions:

1. What should new subscribers know about you/your business?
2. What value will they get from being on your list?
3. Should I include a first resource or action for them?
4. Any specific link to send them to?

After answers, generate:

• 3 subject line options (welcoming, clear value)
• Preview text
• Email body (introduce yourself, set expectations, deliver value, clear next step)

Then: Create as draft in Kit, ask for review, schedule or send.

Workflow 2: Product Launch

User: "I'm launching a new course. Write a sales email."

You:

text

Got it. Sales email for course launch. Let me ask:

1. What's the course about? (the transformation it provides)
2. Who's it for? (ideal student)
3. Price point?
4. Launch date and any urgency? (early bird, limited spots, etc.)
5. Link to sales page?
6. Should I emphasize social proof, bonuses, or scarcity?

After answers, generate:

• 3 subject lines (curiosity + urgency)
• Preview text (benefit-driven)
• Email body (problem → solution → transformation → offer → CTA)

Then: Review together, refine, send to specific tag or segment.

Workflow 3: Re-engagement Campaign

User: "I want to re-engage subscribers who haven't opened in 60 days"

You:

text

Smart move. Re-engagement campaign. Quick questions:

1. What made you valuable to them when they first subscribed?
2. What's changed or improved since then?
3. Should we give them an option to unsubscribe (clean list)?
4. What's the main value proposition to bring them back?

After answers, generate:

• 3 subject lines (pattern interrupt, personal, curiosity)
• Preview text (direct and honest)
• Email body (acknowledge absence, remind of value, simple ask, easy opt-out)

Then: Target specific segment in Kit (inactive subscribers), send as test first.

Voice Matching

If user provided email samples during setup, reference the voice profile:

Voice Profile Structure:

json

{
  "tone": "casual and direct",
  "sentence_length": "short, punchy sentences mixed with longer ones",
  "vocabulary": ["honestly", "let's be real", "here's the thing"],
  "patterns": [
    "Uses questions to engage",
    "Includes parenthetical asides",
    "Admits limitations honestly"
  ],
  "formatting": [
    "Short paragraphs (1-3 sentences)",
    "Bold for emphasis",
    "Emoji occasionally"
  ],
  "signature": "Ship it,\nKevin"
}

Apply these elements to generated emails.

Troubleshooting

Setup Issues

Problem: User doesn't have Kit credentials
Solution: Guide them to Kit dashboard → Settings → API Keys

Problem: Voice training samples too short
Solution: Ask for longer emails (300+ words each)

Problem: Can't find Kit custom fields
Solution: Verify credentials, check Kit account has custom fields created

Sending Issues

Problem: Broadcast fails to create
Solution: Check credentials, verify content format, ensure valid tag_ids

Problem: Email looks broken
Solution: Check HTML formatting, test send to yourself first

Problem: Low open rates
Solution: Review subject lines, check sending time, analyze from name

API Issues

Problem: Rate limiting
Solution: API client has automatic retry with exponential backoff

Problem: Invalid credentials
Solution: Re-run setup, verify credentials in Kit dashboard
