Watch, then do it yourself in the free practice copy. ### Automate a lead magnet welcome email with AI Short · 0:52 Every signup asked about something different, so one welcome email doesn't fit. An n8n AI agent tags each lead with one segment and emails the guide plus one tip that matches. No discounts, no health claims. ## What you will build You will build a [lead magnet](https://learn.ynteractive.com/content/glossary/lead-magnet) signup form for Harbor & Pine Coffee Roasters, a small online coffee brand used as the example. The form offers a free brewing guide called The Better Cup at Home and asks four things: name, email, what the person wants to improve and, optionally, how they brew now. Behind the form is an [n8n workflow](https://learn.ynteractive.com/content/glossary/workflow). When someone submits, a [webhook](https://learn.ynteractive.com/content/glossary/webhook) receives the data and an AI agent reads it. The agent tags the lead with one of four segments (New to Brewing, French Press & Pour-Over, Espresso at Home or Gift Buyer), adds a row to a Google Sheet called Leads, and uses Gmail to send a short welcome with the guide link and one tip that fits their segment. A Respond node tells the form it worked, and the visitor sees "Check your inbox!" In the test, Jordan says their French press coffee tastes bitter and muddy. The agent tags Jordan as French Press & Pour-Over, saves the row and emails the guide with a tip for that brew method. ## Who this is for This is for small business marketers who have a guide, checklist or recipe card to give away and no time to send it by hand. It fits store owners, solo marketers and small teams who want every signup segmented from day one, without buying an email platform add-on to do it. It is the most complete of the three marketing modules, because it joins a real web app to an AI backend. No coding is needed. ## Why it works Most signup forms treat every lead the same. Here the two questions on the form give the agent something to work with, and the system message turns that into a clear segment and a relevant tip. The person gets a welcome that answers the problem they just told you about, and you get a list you can already sort. The pieces each do one job. Lovable builds the page. The webhook receives the data. The agent decides the segment and writes the email. Sheets keeps the record and Gmail delivers it. Because the webhook URL is stored as a secret, you can change the workflow later without touching the form. ## How to use this in your business Replace the brewing guide with your own lead magnet and rewrite the two questions so the answers tell you something useful, like what a visitor wants help with and where they are starting from. Then rewrite the segments in the system message to match how you actually market: by product line, by experience level or by buyer type. Once it is running, sort the Leads sheet by interest to plan your next emails, and use the segments to decide who hears about which product first. Keep the rules in the system message strict: no discounts you do not offer and no claims you cannot back up. ## What you need - For the practice copy here: nothing. No form is published and no email is sent. - For the real build: a Lovable account, an n8n account, an OpenAI account with a little credit, and a Google account for Sheets and Gmail. - A guide to give away, saved somewhere you can link to it. ## Try it yourself, free Reading the steps is a start. Doing them is how it sticks. The interactive module walks you through every click in a practice copy of Lovable and n8n, checks each step, and never touches your real accounts. [Start “Build a Lead Magnet Signup Form with an AI Welcome Email”](https://learn.ynteractive.com/modules/lovable-n8n-marketing) ## Step by step: Build a Lead Magnet Signup Form with an AI Welcome Email All 93 steps of the interactive module, in order. In the module you watch each one, then do it yourself in a practice copy that checks your work. ### 1. Sign up 1. **Get started with Lovable.** Lovable lets you build web apps by describing what you want. Click **Get started for free**. In the first module you built a Custom GPT. In the second, you built an AI agent inside n8n. Now you are going to combine a real web app with an AI-powered backend. Lovable is a tool that builds web apps from a text description. ### 2. Build the form 2. **Click the prompt box.** This is your Lovable dashboard. To start a new project, click the prompt box under **What should we build, Alex?** This is your Lovable dashboard. Your projects show up along the bottom. To start a new one, you just describe it. 3. **Describe the form.** This prompt tells Lovable exactly what to build — a free guide signup form that sends data to an n8n webhook. Paste in the prompt on the box. This prompt tells Lovable what to build: a free guide signup form with name, email, what they want to get better at, and how they brew now, sending each signup to an n8n webhook URL pulled from a secret config — not hardcoded. ```text Build a simple, clean lead magnet signup form for a small online coffee brand. The page should be modern, minimal, and warm. Include these fields: Name Email What do you want to improve? How do you brew now? Use a clear heading such as: Get the Free Guide Add a short supporting line like: The Better Cup at Home: our free brewing guide, sent straight to your inbox. WEBHOOK When the form is submitted, send the data as a POST request to the n8n webhook URL. The data should be sent as JSON with keys: name, email, interest, brewMethod. Do not ask me to paste the webhook URL into the page or source code. SUBMISSION STATES While submitting, change the button text to something like: Sending... After a successful submission, show: Check your inbox! Your free guide is on its way. If the webhook request fails, show a simple friendly error: Something went wrong. Please try again. VALIDATION Require Name, Email, and What do you want to improve. How do you brew now is optional. Validate the email format. Make it responsive for desktop and mobile. Do not add unnecessary sections, navigation, pricing, testimonials, or other marketing content. The main purpose of this project is to send guide signups from Lovable to an n8n webhook. IMPORTANT Do not hard-code any webhook URL. Reference the N8N_WEBHOOK_URL secret/config value when sending the form submission. The actual secret will be added manually later in Lovable Cloud, under Secrets. ``` 4. **Open the mode picker.** Next to the microphone it says **Build**. That is the mode picker. Click it. Before you send it, look at the word Build next to the microphone. That's the mode picker. 5. **Keep Build mode.** **Build** makes changes directly, **Chat** is for questions, **Plan** writes a detailed plan first. Click **Build**. Build makes changes directly. Chat is for asking questions and exploring ideas, and Plan writes a detailed plan first, which helps on bigger projects. This form is simple, so click Build. 6. **Build the app.** Click the **send arrow**. Lovable builds the app from your prompt and shows it in a preview. Then we switch to n8n to build the backend. Lovable reads your prompt, generates the code, and builds a preview of the app. Nothing is public until you publish it. In a few seconds you have a working signup form. Now we build the AI workflow that handles each signup. ### 3. New workflow 7. **Start a new workflow.** Now you are in n8n. Click **Create workflow** to start building the backend. Now you are in n8n. This is the workflow automation tool you used in the last module. This time, instead of a chat trigger, we are going to use a webhook — so the form can send data directly to n8n. ### 4. Webhook trigger 8. **Add the first step.** Click **Add first step…** to choose a trigger. Every workflow starts with a trigger. Last time we used a chat trigger. This time we want a webhook — an HTTP endpoint the form can POST to. 9. **Webhook trigger.** Click **On webhook call** — the form will send data to this endpoint. On webhook call. A webhook is just a URL that waits for incoming data. When someone asks for the guide, the form sends their name, email, interest, and brew method as JSON to this webhook. 10. **Change the response mode.** By default the webhook responds immediately. We need it to wait. Click the **Respond** dropdown. One important setting. By default, the webhook responds immediately, before the AI agent even runs. We need it to wait until the agent is done, so the form knows the submission succeeded. 11. **Use a Respond node.** Click **Using 'Respond to Webhook' Node** — this lets the workflow finish before responding. Using respond to webhook node. This tells n8n: do not send a response yet. Wait until you hit a dedicated respond node further down the chain. That way the form gets a real confirmation after the AI agent has processed everything. 12. **Back to the canvas.** Webhook is configured. Close the node with the **×**. That is the webhook set up. Close the node. ### 5. AI Agent 13. **Add the next node.** Click the **+** on the right edge of the webhook node. Now we decide what happens when the form data arrives. 14. **Add the AI Agent.** Click **AI Agent** — it will process the form data, save it to a sheet, and send an email. AI Agent. Same node as last time, but now it handles form submissions instead of chat messages. It will read the form data, save it to Google Sheets, and send a personalized reply via Gmail. 15. **Change the prompt source.** This time we are not using a chat trigger. Click the **Source** dropdown. This time the prompt does not come from a chat trigger — it comes from the webhook. We need to change the source so we can write our own prompt template. 16. **Define it manually.** Click **Define below** so we can write a custom prompt template. Define below. This lets us write a prompt that pulls the form fields directly from the webhook data. 17. **Write the prompt template.** This template pulls the form fields from the webhook data. Paste in the prompt template. Here is the prompt template. Those double curly braces are n8n expressions that pull the name, email, interest, and brew method from the webhook body, so the agent gets the real details every time. 18. **Add an option.** Scroll down and click **+ Add Option** to add a system message. Now we need a system message — the standing instruction that tells the agent what to do with every submission. 19. **System Message.** Click **System Message**. System message. This is where we tell the agent to save the lead to Google Sheets and send a reply email via Gmail. 20. **Write the system message.** This tells the agent to tag the lead, save it to Sheets and email the guide. Paste in the system message. Here is the system message. It tells the agent to tag each lead with one of four segments, save the lead with the Google Sheets tool, and email the guide with a tip that fits their segment. ```text You are the welcome email assistant for Harbor & Pine Coffee Roasters, a small online coffee brand. Tag each new lead with one segment: New to Brewing, French Press & Pour-Over, Espresso at Home, or Gift Buyer. Use the google sheets tool to add the lead to the google sheet. Use the gmail tool to email the lead a short, warm welcome with a link to The Better Cup at Home guide, plus one tip that fits their segment. No discounts and no health claims. ``` 21. **Back to the canvas.** The agent knows what to do. Close the node with the **×**. The agent is configured. It knows to save to Sheets and reply via Gmail. Close the node. ### 6. Chat model 22. **Give the agent a brain.** The agent still needs a language model. Click the **+** under **Chat Model**. The agent needs a model to think with. 23. **Pick OpenAI.** Click **OpenAI Chat Model**. OpenAI Chat Model. If you did the last module, this part will feel familiar. 24. **Open the credentials.** Click the **Credential** dropdown. 25. **Create a new credential.** Click **+ Create new credential**. Create new credential. If you already made one in the last module, you could pick it from the list. We will create a fresh one here. 26. **Paste the key.** Paste in the API key to drop in your OpenAI key. No key yet? Make one at platform.openai.com (add credit first), or in your own n8n pick **Gateway credits** and skip this step. If you followed the previous module, you already have one. If not, go to platform dot openai dot com, add credit, and create a key. Or skip it: new n8n accounts include free credits, so in your own n8n you can pick gateway credits instead. 27. **Save the credential.** Click **Save**. n8n tests the connection and stores the key. 28. **Pick the model.** Click the **Model** dropdown. Now the model dropdown. 29. **gpt-5-mini.** Pick **gpt-5-mini** — fast and cheap. GPT five mini. Fast, cheap, and plenty smart for processing form submissions. 30. **Back to the canvas.** Close the model node with the **×**. Model is wired up. Close it. ### 7. Sheets tool 31. **Add a tool.** The agent needs tools to do things. Click the **+** under **Tool**. Now the tools. The system message told the agent to use Google Sheets and Gmail — but it cannot do either until we give it the actual tools. 32. **Add Google Sheets.** Click **Google Sheets Tool**. Google Sheets Tool. This lets the agent save form submissions as rows in a spreadsheet. ### 8. Create the spreadsheet 33. **Back to the canvas.** Before configuring this, create the spreadsheet it will write to. Close the node for now. Before we configure this node, we need to create the actual spreadsheet. Close this for now — we will come right back. 34. **Open Google Sheets.** Click the **Google Sheets** tab to create a new blank spreadsheet. Switch to the Google Sheets tab. You need to create the spreadsheet that the Sheets node will write to. 35. **Name the spreadsheet.** Click the title and rename it to **Leads**. Name it Leads — this is where every guide signup will go. 36. **Type the first column header.** In cell **A1**, type **Name**. Now set up the column headers. These need to match the form fields. In A1, type Name. 37. **Email.** In cell **B1**, type **Email**. B1 — Email. 38. **Interest.** In cell **C1**, type **Interest**. C1 — Interest. 39. **Brew Method.** In cell **D1**, type **Brew Method**. That is all four columns — matching the form. And D1 — Brew Method. Four columns, matching exactly what the form sends: name, email, interest, brew method. 40. **Back to n8n.** The spreadsheet is ready. Click the **n8n** tab to go back and connect it. The spreadsheet is ready. Switch back to n8n and connect the Google Sheets node to it. 41. **Open the Sheets node.** Double-click the **Google Sheets** node to configure it. Double click the Google Sheets node to open it up again. Now we can connect it to the Leads spreadsheet. ### 9. Sheets tool 42. **Add a credential.** Click the **Credential** dropdown. 43. **Create a new credential.** Click **+ Create new credential** to sign in with Google. Create new credential. This one uses Google OAuth, so it opens a credential window. 44. **Sign in with Google.** Click **Sign in with Google** to connect your account. This opens the Google account chooser. 45. **Choose your account.** Click your **Google account** to continue. Pick the Google account that owns the Leads spreadsheet. 46. **Allow Sheets access.** Check **See, edit, create, and delete all your Google Sheets spreadsheets**. Google is asking for permissions. Check the first box — this lets n8n read and write your spreadsheets. 47. **Allow Drive access.** Check **See, edit, create, and delete all of your Google Drive files**. Second box — Drive access so n8n can find your spreadsheets by name. 48. **Allow external service.** Check **Connect to an external service**. Last one — this lets Google connect to n8n as an external service. 49. **Sign in.** Click **Continue** to complete the Google sign-in. All three checked. 50. **Pick the spreadsheet.** Click the **Document** dropdown. Now pick the spreadsheet. 51. **Leads.** Click **Leads** — the spreadsheet where guide signups go. Leads — this is the spreadsheet where every form submission gets saved as a row. 52. **Pick the sheet tab.** Click the **Sheet** dropdown. 53. **Sheet1.** Click **Sheet1**. Sheet one. That is the only tab. 54. **Map the Name column.** Under **Values to Send**, click the **✦** button next to **Name** — the AI agent will fill this in automatically. Now the column mapping. Each column in the spreadsheet has a purple button. 55. **Map the Email column.** Click the **✦** button next to **Email**. Email. 56. **Map the Interest column.** Click the **✦** button next to **Interest**. Interest. 57. **Map the Brew Method column.** Click the **✦** button next to **Brew Method**. And Brew Method. All four columns are now set to defined automatically by the model. 58. **Back to the canvas.** Google Sheets is configured. Close the node with the **×**. Sheets tool is fully configured — credential, spreadsheet, sheet, and column mapping. Close it. ### 10. Gmail tool 59. **Add another tool.** The agent also needs to send emails. Click the **+** next to Google Sheets to add another tool. The agent can save to Sheets now, but it also needs to send a reply email. 60. **Add Gmail.** Click **Gmail Tool**. Gmail Tool. This lets the agent send a personalized reply back to whoever submitted the form. 61. **Add a credential.** Click the **Credential** dropdown. Gmail uses the same Google OAuth as Sheets. 62. **Create a new credential.** Click **+ Create new credential** to sign in with Google. Create new credential. Gmail needs its own Google OAuth credential. 63. **Sign in with Google.** Click **Sign in with Google** to connect your account. Same flow as before — Google account chooser then permissions. 64. **Choose your account.** Click your **Google account** to continue. Pick the Google account you want to send emails from. 65. **Allow email access.** Check **Read, compose, send, and permanently delete all your email from Gmail**. Google is asking for permissions. Check the first box — this gives n8n full email access. 66. **Allow drafts.** Check **Manage drafts and send emails**. Second box — manage drafts and send emails. 67. **Allow compose.** Check **Read, compose, and send emails from your Gmail account**. Read, compose, and send. 68. **Allow metadata.** Check **View your email message metadata**. View email message metadata. 69. **Allow modify.** Check **View and modify but not delete your email**. View and modify but not delete. 70. **Allow view.** Check **View your email messages and settings**. Last one — view your email messages and settings. 71. **Sign in.** Click **Continue** to complete the Google sign-in. All six checked. 72. **Back to the canvas.** Gmail is connected. Close the node with the **×**. Gmail is connected. The agent can now send emails. Close the node. ### 11. Respond node 73. **Add the respond node.** One more node. Click the **+** on the right edge of the AI Agent. One last piece. Remember we told the webhook to wait for a respond node before sending back a reply? We need to add that node now. 74. **Respond to Webhook.** Click **Respond to Webhook**. Respond to Webhook. When the agent finishes processing — saving to Sheets and sending the email — this node sends a success response back to the form, so the user sees a confirmation message instead of an error. 75. **Back to the canvas.** Nothing to configure here. Close the node with the **×**. Nothing to configure. This node just sends back the response. Close it. ### 12. Publish 76. **Publish the workflow.** The workflow is complete. Click **Publish** to make it live. The workflow is complete. Webhook trigger, AI agent with a model, Google Sheets, Gmail, and a respond node. Once published, the webhook URL is active and ready to receive form submissions. ### 13. Add the secret 77. **Open the webhook.** Double-click the **Webhook** node to get its production URL. The workflow is published, but Lovable still needs the webhook URL. 78. **Production URL.** Click the **Production URL** tab — this is the live URL your form will POST to. Switch to the production URL tab. The test URL only works during testing. The production URL is the one your published workflow uses. 79. **Copy the URL.** Click the URL to **copy** it. You will paste it into Lovable as a secret. You will paste this into Lovable so the form knows where to send data. 80. **Back to the canvas.** URL copied. Close the webhook node. Got the URL. Close the node. 81. **Back to Lovable.** Click the **Lovable** tab. We need to give it the webhook URL. Switch back to Lovable. We need to paste the webhook URL into a secret so the form can reach the workflow. 82. **Open More.** Your app is open in the Lovable editor: chat on the left, preview on the right. In the toolbar at the top, click **More** (the stacked icon right after **Code**). Here is your app in the Lovable editor, with the chat on the left and the preview on the right. Secrets live in the More view. In the toolbar at the top, click the stacked icon right after the code brackets. That's More. 83. **Open Cloud.** More holds your project tools. Click **Cloud** in the list on the left. More holds the tools for running your app, starting with Analytics. Secrets belong to Cloud, Lovable's built-in backend. 84. **Open Secrets.** Cloud opens on its **Overview**. Click **Secrets** in the list. Cloud opens on its overview, and its pages are listed on the left. 85. **Name the secret.** Paste in the secret name — this matches what the Lovable app expects. This is the secrets page. The prompt told Lovable to reference a secret config value called N8N WEBHOOK URL instead of hardcoding it. 86. **Paste the webhook URL.** Paste in the webhook URL to drop in the production URL you just copied. This is the live endpoint your form will POST to. 87. **Save the secret.** Click **Save**. The Lovable app can now reach the n8n workflow. The Lovable app now knows where to send form submissions. The webhook URL is stored as a secret, not in the source code — exactly how it should be. ### 14. Test the form 88. **Open the form.** Click **Preview** (the globe icon) in the toolbar to test the form. Time to test. 89. **Fill the form.** Click **Fill with test data** to populate the form fields. Fill out the form with sample data. 90. **Submit the form.** Click **Send Me the Guide**. The form sends the data to n8n; the agent tags the lead, saves it to Sheets and emails the guide. The form posts the signup to the n8n webhook. The agent sees bitter French press coffee, tags the lead French press and pour-over, saves a row to Google Sheets, and emails the guide with a French press tip through Gmail. The respond node sends back a success message, and the form shows the confirmation. ### 15. Publish the app 91. **Open Publish.** The test went through. The preview is only for you, so click **Publish** at the top right to put the form online. The test went through. But the preview is only for you. To put the form online, click Publish at the top right. 92. **Publish.** Lovable suggests a free **lovable.app** address (you can change it) and runs a quick security scan. Click **Publish**. Lovable suggests a free web address ending in lovable dot app, and you can change it before you publish. It also runs a quick security scan. The live app uses the same secret, so it sends to your workflow too. 93. **Check the spreadsheet.** Your app is live. Click the **Google Sheets** tab to see the data the agent saved from your test. Your app is live. Now check the spreadsheet. ## More videos from this lesson ### AI Lead Magnet Signup Form with Lovable + n8n for marketers: the 1-minute version Highlight · 1:05 · with captions Build a "Get the free guide" signup form in Lovable for Harbor & Pine Coffee Roasters and connect it to n8n — the AI agent tags each lead by interest, saves it to Google Sheets and emails a personal welcome with the guide.
