Replay historical conversations, create test scenarios, and save conversation snapshots to verify and improve how Blueberry handles different customer interactions. Think of the Sandbox as your campaign quality assurance lab - catch issues before they reach customers and ensure perfect execution every time. ## Sandbox Capabilities Load real DM threads and replay them to see how Blueberry would respond at different points in the conversation. Save conversation snapshots at specific points to repeatedly test and refine responses. Build custom test conversations from scratch to verify how Blueberry handles different scenarios. ## Accessing the Sandbox Click **Sandbox** in the sidebar navigation or go to **DMs** → **Test Sandbox**. Select one of three options: - Load a real conversation thread - Load a saved snapshot - Start from scratch Interact with the conversation explorer to test how Blueberry would respond at different points. ## How to Use the Sandbox Load a real DM thread and test how Blueberry would respond at different points in the conversation. Click the **Threads** tab in the sidebar and select a DM conversation from your inbox. The original conversation appears on the left panel. You can see all messages exchanged between your brand and the customer. Click **"Copy from here"** on any customer message to test how Blueberry would respond from that point forward. Click **"Generate next message"** to see what Blueberry would respond. The response appears in the right panel. Add follow-up customer messages and continue generating responses to test multi-turn conversations. Use **"Regenerate from"** on any message in the original conversation to test alternative response paths. Save conversation snapshots at specific points for repeated testing and collaboration. While viewing a thread or testing a conversation, click **"Save snapshot"** on any message to capture the conversation up to that point. Give the snapshot a descriptive name like "VIP customer complaint" or "Product inquiry - pricing question". Click the **Snapshots** tab in the sidebar to see all saved snapshots. Select one to load it. Use snapshots to consistently test the same scenario after updating your brand voice or documentation. Snapshots are perfect for regression testing - verify Blueberry still handles important scenarios correctly after making changes. Build custom test conversations to verify Blueberry handles specific scenarios. Click **"Start from scratch"** to create a blank test conversation. Type a customer message to test how Blueberry would respond. For example: "Do you offer refunds?" Click **"Generate next message"** to see Blueberry's response. Continue adding customer messages and generating responses to test complex conversation flows. Edit any message in the conversation to test different variations and edge cases. Create conversations for common customer scenarios like returns, shipping questions, or product inquiries to ensure Blueberry handles them well. ## Key Features Test how Blueberry's AI would respond to any customer message based on your brand voice and documentation. * See generated responses in real-time * View reasoning behind each response * Test multi-turn conversations * Edit messages and regenerate to test variations Navigate through conversations with powerful tools: * **Copy from here** - Test from any point in a conversation * **Regenerate from** - Generate alternative responses from historical messages * **Reset** - Clear the test panel and start fresh * **Save snapshot** - Capture conversation state for future testing Edit any message in the conversation to test different scenarios: * Modify customer messages to test edge cases * Test different phrasings and tones * Add or remove context to see how it affects responses * Build complex conversation flows When testing with real threads, Blueberry uses actual contact information: * Previous conversation history * Contact metadata and attributes * Real brand voice and documentation * Campaign context if applicable ## Best Practices Test responses after any changes to brand voice, documentation, or rules. Save snapshots of important scenarios for regression testing. Don't just test happy paths. Test unusual requests, angry customers, and confusing messages to ensure Blueberry handles them gracefully. Load actual customer threads to test real-world scenarios. This gives you the most accurate testing context. Create snapshots for critical conversation types like returns, complaints, and product inquiries to test repeatedly. ## FAQ No. The sandbox only generates and previews responses. No messages are sent to real customers. Blueberry analyzes the conversation context, your brand voice, and documentation to generate an AI response. No. Snapshots are static captures of a conversation at a specific point in time. They won't change even if the original thread receives new messages. Yes. All team members with access to your brand can see and load saved snapshots. This is useful for training and ensuring consistent response quality. Blueberry may decide not to respond if: - The customer's message doesn't require a response (e.g., "Thanks!") - The conversation has naturally concluded - The message is unclear and needs clarification from the customer Yes, when loading real threads. The sandbox uses actual contact data including segment memberships, interaction history, and attributes. ## Related Pages Set up your brand voice and documentation to improve AI responses.
