Auto-Send DMs to LinkedIn Commenters Who Type a Specific Keyword using ConnectSafely.AI API Who's it for This workflow is built for content creators, coaches, course sellers, and marketers who use the "comment X to get the link" engagement strategy on LinkedIn. Perfect for anyone who wants to deliver lead magnets, code samples, templates, or resources automatically without spending hours manually DMing every commenter. If you're tired of the manual grind—reading comments, checking connections, copy-pasting messages—this automation handles the entire fulfillment process while you focus on creating more content. Works especially well for viral posts where comment volume makes manual responses impossible. How it works The workflow monitors your LinkedIn post for specific keyword triggers and automatically sends personalized DMs to commenters who request your content. The process flow: You submit your post URL, trigger keyword, and resource link via a simple form Fetches all comments from the specified LinkedIn post via ConnectSafely.ai API Loops through each comment individually for processing Detects if the comment contains your trigger keyword (case-insensitive) Checks if the commenter is a 1st-degree connection (required for DMs) Sends a personalized direct message with their name and your resource link Applies random rate limiting (15-30 minutes) between messages for account safety Continues until all matching comments are processed The rate limiting and connection checks are built-in to protect your LinkedIn account from automation detection.

Step 5: Activate for Production Review the test execution to ensure messages sent correctly Toggle the workflow to Active Use the form URL whenever you post new "comment for link" content The workflow processes comments and sends DMs automatically Customization Message Template Edit the Send DM with Link node to customize your message: Hey {{name}}! 👋 Thanks for your comment on my post! As promised, here's the link you requested: 👉 {{link}} If you have any questions or want more resources like this, just let me know! Best, {{your_name}} Variables available: {{ $('Loop: Process Each Comment').item.json.authorName }} - Commenter's name {{ $('Form: Enter Post Details').item.json['Content Link to Send'] }} - Your resource link {{ $('Form: Enter Post Details').item.json['Your Name (for signature)'] }} - Your name Multiple Keywords Edit the Detect Keyword Match code node to check for multiple trigger words: // Multiple keyword detection const keywords = ['code', 'example', 'template', 'link', 'send']; const commentLower = commentText.toLowerCase(); const isMatch = keywords.some(keyword => commentLower.includes(keyword.toLowerCase()) ); return [{ json: { isKeywordMatch: isMatch, commentText } }]; Rate Limiting Adjustment Edit the Wait: Rate Limiting node to change delays: | Risk Level | Wait Time | Formula | |------------|-----------|---------| | 🟢 Safest | 30-60 min | Math.floor(Math.random() * (3600 - 1800 + 1)) + 1800 | | 🟡 Moderate (Default) | 15-30 min | Math.floor(Math.random() * (1800 - 900 + 1)) + 900 | | 🔴 Faster (Risky) | 5-15 min | Math.floor(Math.random() * (900 - 300 + 1)) + 300 | Warning: Shorter delays increase the risk of LinkedIn flagging your account. Add Connection Requests (Optional) To also send connection requests to non-connected commenters: Add a ConnectSafely LinkedIn node after the "If: Connected?" FALSE path Set operation to sendConnectionRequest Map the publicIdentifier from the loop Add a personalized connection message Use Cases Lead Magnet Distribution**: Automatically deliver PDFs, guides, or checklists to everyone who comments Code Sample Sharing**: Share GitHub repos, code snippets, or template files to developers who request them Course Previews**: Send free lesson links or course previews to interested commenters Template Giveaways**: Distribute Notion templates, spreadsheets, or design files Webinar Registrations**: Send signup links to commenters interested in your events Community Building**: Deliver exclusive Discord/Slack invite links to engaged followers Podcast Promotion**: Share episode links or show notes with interested listeners Newsletter Growth**: Send subscription links with a teaser of your best content Troubleshooting Common Issues & Solutions Issue: No comments returned from post Solution**: Verify the post URL is correct and complete (should include the full linkedin.com/posts/... URL) Solution**: Ensure the post is public or you're the post author Solution**: Check that the post actually has comments Issue: "Cannot send message" errors Solution**: You can only DM 1st-degree connections on LinkedIn; non-connections are automatically skipped Solution**: The commenter may have messaging disabled in their settings Issue: Messages not being sent Solution**: Verify your ConnectSafely.ai credentials are valid and connected Solution**: Check that your LinkedIn account is properly connected in ConnectSafely dashboard Solution**: Review the execution log for specific error messages Issue: Keyword not matching comments Solution**: Keywords are case-insensitive, but check spelling Solution**: Ensure the keyword appears exactly in the comment (partial matches work) Solution**: Test with a simple, unique keyword first Issue: Workflow seems slow Solution**: This is intentional! The 15-30 minute delays between messages protect your account Solution**: Large batches (50+ comments) will take several hours to complete safely Issue: LinkedIn account warnings Solution**: Stop the workflow immediately Solution**: Wait 24-48 hours before resuming Solution**: Increase rate limiting delays when you restart Solution**: Reduce daily volume Issue: Duplicate messages sent Solution**: Don't run the workflow multiple times on the same post Solution**: Consider adding a Google Sheets node to track processed commenters Safety Best Practices LinkedIn Account Protection | Do ✅ | Don't ❌ | |-------|---------| | Use random delays (built-in) | Send messages without delays | | Process 20-30 comments per batch | Process 100+ comments at once | | Run during business hours | Run 24/7 continuously | | Stop if you see warnings | Ignore LinkedIn restrictions | | Keep messages helpful | Send salesy/spammy content | | Respond to genuine requests | Use for cold outreach | Daily Limits (Approximate) | Account Type | Recommended Max DMs/Day | |--------------|------------------------| | Free Account | 30-50 | | Premium | 50-80 | | Sales Navigator | 80-100 | These are conservative estimates.
