How this works
This workflow automates direct messaging on social platforms by scanning comments for specific keywords and sending personalised responses, saving hours of manual monitoring and outreach. It's ideal for social media managers, marketers, or community builders who want to engage leads efficiently without constant oversight. The key step involves looping through fetched comments to check for keywords, then using ConnectSafely AI to generate and dispatch tailored DMs only to relevant users.
Use this when handling high-volume comment threads on platforms like Instagram or Twitter, where timely keyword-based engagement boosts conversion rates. Avoid it for low-traffic accounts or when privacy rules prohibit automated messaging, as it requires careful setup to comply with platform terms. Common variations include adding filters for user verification or integrating with email notifications for follow-ups.
