--- title: 4. Master template slug: lf-lab/4-master-template docTags: createdAt: 2026-05-19T07:41:37.298Z --- ### Narrative context The wait is over. The journey is about to send the most important message of the experience: a personalised recap of the customer's simulation, with the offer best suited to them, in the voice of their local LF company. The same email object will produce brand-distinct outcomes at send time, one for each LF company. This exercise builds the structure that makes that possible. ### Open the master template and explore content locking - In the left menu, under **Content management**, click **Templates**. - Find **LF - Mortgage Comms** and click its name to open it. The template opens in the email designer. We will explore content locking directly inside the editor — it is much clearer with the email open than as an abstract concept. - Click **Edit email body**. - On left menu, click the icon :inlineImage[]{src="https://api.archbee.com/api/optimize/1Jp0iolWv35Z_mkI7oUiT/LJBLiEer0vD9lyT1B8MV9-20260520-161432.jpg" alt caption width="30" height="30"} to open the navigation tree. A lock icon appears next to each block that has been locked by the creator. The **Structure 1**, that contains the Header, is **locked** by the central template owner. Click on it so see the settings - Click the **Structure 6** block at the bottom — same behaviour. - Now click the **Hero image** area in the middle. It opens normally for editing. ### Add the conditional content - hero image and headline Let's use the template as starting point to create the full email. - Use the arrow on the top left corner to exit the template. - If prompt, click on **Close without saving**. - Then click on **Journeys** and open the journey you were working on. In the left panel, click the **Actions** tab. - Drag **Action** onto the **24h** path. - In the window that appears, select **Email** and click **Add**. - In the Properties panel, set the label to `Follow up email`. - Merge the **72h** branch in the same node. - Click the email node to open the properties. - Click **Configure action**. - In the **Email channel configuration**, select `Email-Marketing` from the dropdown. - Click on **Edit content**. :::hint{type="warning"} **IMPORTANT**: click the **Enable decisioning** toggle and click **Continue**. This is required for the next exercise. ::: - Click on **Content template**. - Select **Apply content template**. - From the list select **LF - Mortgage Comms** and click **Confirm**. - Click **Edit email body**. Five mortgage purposes produce five different hero images and headlines. The same email body chooses among them at send time based on the context. - In the body, click the hero image block, slightly outside the image, to select the entire block. - The border of the block is orange because **Conditional content** are already enabled. - In the left menu click on icon :inlineImage[]{src="https://api.archbee.com/api/optimize/1Jp0iolWv35Z_mkI7oUiT/H8vO3WOh_hHGam9t4s6hU-20260416-095824.png" alt caption width="26" height="26"} to see **Conditional content: **the list of variants appears. Four conditions are already pre-built in the template (for first\_time\_purchase, renovation, second\_home\_purchase, cash\_out). You will author one new condition for the missing refinancing purpose. - Click **Add variant**. - Click the icon :inlineImage[]{src="https://api.archbee.com/api/optimize/1Jp0iolWv35Z_mkI7oUiT/BXuvViRUOH7wYRzSkMK8C-20260520-163943.jpg" alt caption width="43" height="43"} the **Rename** and set the name to `refinancing`. - Click the icon :inlineImage[]{src="https://api.archbee.com/api/optimize/1Jp0iolWv35Z_mkI7oUiT/T1Bb16ndMTFaEjLOy3A23-20260416-100139.png" alt caption width="22" height="22"} to select the condition. - Click **Create new** to create a new condition for your needs. - On the left, select the **Contextual** tab. - Search for `purpose`. - Drag the item into the canvas and set the value to `refinancing`. - Click **Save condition**. - Set the title to `[{{LASTNAME}}] Mortage purposa - refinancing`. - Click **Add**, then click **Select**. - Set the **Headline** field. You have two options — try both and pick the one you prefer: - Type it manually: `Move your mortgage to a place that listens`. - Or click the icon :inlineImage[]{src="https://api.archbee.com/api/optimize/1Jp0iolWv35Z_mkI7oUiT/NdNmf4mzNJc_B27WpDqRC-20260520-161719.jpg" alt caption width="31" height="31"} in the right menu (if prompted agree to the terms) - enter the prompt `Short, institutional headline for a mortgage refinance email. Calm, deliberate tone. No exclamation marks.` - Click **Generate**. - Pick one of the variants the assistant proposes by clicking **Apply**. - Click **Save**. ![](https://api.archbee.com/api/optimize/1Jp0iolWv35Z_mkI7oUiT/92Eln5GZiOZVHG9CXO6ac_image.png) ### Generate image with AI Four of the five hero images are pre-loaded. The refinancing (mortgage refinance) variant is missing - you will generate it now to learn the Firefly flow with the LF Group brand profile. - Click on the **Hero image** to select the block. - In the right panel, click the icon :inlineImage[]{src="https://api.archbee.com/api/optimize/1Jp0iolWv35Z_mkI7oUiT/NdNmf4mzNJc_B27WpDqRC-20260520-161719.jpg" alt caption width="31" height="31"}. The Firefly composer opens with the LF Group brand profile already applied (palette, typography, mood). - In the **Prompt** field, enter: :::BlockQuote Tabletop still-life, overhead shot. Notebook with handwritten notes, fountain pen, single coffee cup, small calculator. Muted institutional palette, soft natural light. No people, no text. Mood: thoughtful, deliberate. ::: - Click **Generate**. - Review the four variants AI produces. - Pick the one that best matches an institutional register. - Click **Apply** . - The image will be saved in the Asset repository. In the window click **Next**. - Select the folder **Hands-on Lab > LF** then click **Import**. Now the variant shows the AI generated image. Click on **Default** variant to see the difference. - Click **Save**. - Click the arrow on the top-left corner to go back to the canvas email wizard. - Click the arrow on the top-left corner to go back to the canvas. :::hint{type="info"} The brand profile constrains AI to LF's palette and mood. This is why a single prompt produces on-brand outputs without manual adjustment — the profile is doing the heavy lifting. ::: ### Business punchline You have just built a single email object that will produce distinct outcomes at send time without ever cloning the email. The locked header keeps the federation's brand consistent; the lookup dataset adapts the regional voice; the conditional content adapts the message to the customer's intent; the AI Brand profile keeps every newly generated asset on-brand. The customer sees one email, written for them. The marketing team maintains one email, governed centrally.
