Comment-to-DM (also called Comment Automation) automatically sends a direct message when someone comments on your post with a specific keyword.

Example:

• You post: "Comment 'GUIDE' for my free marketing checklist!"
• User comments: "GUIDE"
• They instantly receive a DM with your lead magnet

How to Set Up Comment-to-DM

Step 1: Choose Your Trigger Keyword

Pick something simple and memorable:

• ✅ GUIDE
• ✅ YES
• ✅ LINK
• ✅ FREE
• ❌ "Please send me the marketing guide" (too complex)

Step 2: Create Your DM Sequence

Design what happens after they comment:

1. Welcome message — Thank them and deliver the value
2. Follow-up — Ask a qualifying question
3. Offer — Present your product or service
4. CTA — Clear next step (book call, buy now, etc.)

Step 3: Write Compelling Post Copy

Your post should:

• Clearly state the value they'll receive
• Make the action obvious ("Comment GUIDE below!")
• Create urgency if possible

Step 4: Set Up in ChatAutoDM

1. Go to Automations → Create New
2. Select "Comment-to-DM" trigger
3. Enter your keyword(s)
4. Build your DM flow
5. Select the post(s) to monitor
6. Go live!

Best Practices for Comment Automation

1. Deliver Real Value

Your lead magnet should be genuinely useful:

• Checklists and templates
• Video tutorials
• Discount codes
• Exclusive content

2. Keep DMs Conversational

Avoid walls of text. Break messages into chunks:

• "Hey! 👋 Thanks for commenting!"
• "Here's your free guide: [link]"
• "Quick question — what's your biggest challenge with [topic]?"

3. Use Follow-Up Sequences

Don't stop at one message. Add:

• 24-hour follow-up if they didn't respond
• 3-day check-in with additional value
• Weekly nurture messages

4. A/B Test Everything

Test different:

• Keywords
• DM copy
• Post formats
• Offers

5. Monitor and Optimize

Track:

• Comment-to-DM conversion rate
• DM response rate
• Lead-to-sale conversion
