### Why this automation was built Many leads are lost not because people are not interested, but because no one replies on time or follows up properly. In most cases: - The first reply is delayed - Follow-ups are forgotten - Messages stop after one attempt This automation was built to solve that exact gap — timely and consistent communication, without manual effort. #### What the AI agent handles Once a lead submits a form, the system manages communication across three channels: - Email - WhatsApp - SMS It starts the conversation immediately and continues following up at fixed intervals until the lead responds or the conversation is completed. #### Central structure of the system The entire setup runs on multiple Make scenarios, all connected through a single central database.

Lead submits a form ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/0/5/05dab46b1599f6d4df6186073ede83566cd2e98e.jpeg) The automation starts when a lead submits an inquiry form on the website. ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/b/a/ba231878d3297565138db5cb13dfa648bd2b3966.png) The form collects basic details such as: - Name - Email - Phone number - Budget - Expected visit - Buyer or agent Once submitted: - A unique lead ID is generated - Lead details are stored in the main sheet - The lead ID is passed to the AI agent ## Initial communication (Email) ### 2. First email is sent immediately ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/3/7/3715cce2b4565d1c9018740e04b70f0254ad553f.png) As soon as the lead is created: - An email is drafted using predefined content - The lead’s name and details are filled dynamically - The email is sent without delay After sending: - The full email conversation is captured - Email status and timestamps are stored - Preferred communication mode is set to email This becomes the starting point for all further actions. ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/c/2/c2ee842f565b519c5b1f7a9a159a9e7cc4d446b9.png) ## First follow-up (WhatsApp) ### 3. WhatsApp follow-up after 2 hours ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/f/f/ffda40e655d10465c53533e76b6941509a55064a.jpeg) If no email reply is received within 2 hours: - A scheduled scenario checks eligible leads - A WhatsApp message is sent as the first follow-up WhatsApp is sent using a templated message, as required by the platform. ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/6/0/60175da73632169f2740222645783027eeb81614.jpeg) After sending: - Delivery status is checked - Preferred communication mode is updated to WhatsApp - WhatsApp message details are logged in the sheet If WhatsApp fails to deliver, the system moves to the next fallback. ## Second follow-up (SMS) ### 4. SMS as a fallback channel ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/c/1/c13035776e9285bf02f42addb2ad9a5a969d3def.jpeg) If WhatsApp delivery fails or no response is received: - An SMS is sent as the final outreach - Message status is verified - SMS details are logged ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/6/9/699ae81a7e12b3f64ac6022abd76570136182024.png) This ensures the lead is contacted at least once on all available channels. ## Handling replies from all channels ### 5. Capturing incoming replies Separate scenarios are used to capture replies from: - Email - WhatsApp - SMS Whenever a reply arrives: - The message is stored - Previous conversation history is collected - Everything is sent to the AI agent for context This allows the agent to respond based on past communication, not just the last message. ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/b/4/b44ec4cd5955cebd337f28139e64ad9d74917f92.jpeg) * * * ## AI-based reply generation ### 6. Responding on the right channel The AI agent: - Understands the latest reply - Decides the best channel to continue (email, WhatsApp, or SMS) - Drafts a contextual response - Sends the reply using the same channel All replies are logged and stored back in the database. ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/7/f/7f0bcc07fa452c6165f0ae20a0fd90594fedeca2.png) * * * ## Long-term follow-ups ### 7. Scheduled follow-up logic If a lead stops responding: - Follow-up frequency is decided based on lead age ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/1/9/19f424fc84630f732fa8871a0963fc6db9cd1ea0.png) Example: - 0–2 weeks → follow-up every 3 days - 2–4 weeks → every 5 days - 4–8 weeks → every 7 days - 8–12 weeks → every 14 days Each follow-up: - Uses past conversation context - Respects the preferred communication channel - Stops automatically once the lead status is completed ## What this setup achieves - No lead is left unattended - Communication continues without manual tracking - Every message is contextual and timed - All activity is visible in one place The system works quietly in the background and supports consistent lead handling without replacing human decision-making. This automation focuses on process reliability, not aggressive messaging. It ensures that every inquiry is acknowledged, followed up, and tracked properly across channels. The goal is simple: reduce missed opportunities caused by delayed or forgotten follow-ups.
