Zambo is live (and honest about what it can’t do)\n\nHi [Name],\n\nI’m skipping the pleasantries. You asked for a launch email based on observed checks, not marketing fluff. Here is the draft.\n\n***\n\n**Subject: We built a tool that finds real leads, not just names**\n\nHi [Prospect Name],\n\nI’m writing because you run a [Trade] business in [City]. I’m not here to sell you a subscription or promise you “five qualified leads in 60 seconds” if the data isn’t there.\n\nI built Zambo to solve one specific problem: finding source-backed prospects without inventing fake contacts.\n\nLast week, I ran a test for web design leads in Austin, TX. The system returned zero results. That’s the point. Most AI tools hallucinate contacts to make the demo look good. Zambo doesn’t. If it can’t find a verified source, it tells you there’s no data.\n\nThis means when Zambo *does* return a lead, you know it’s real. No guessing. No wasted time calling phone numbers that don’t exist.\n\nWe’re currently in public beta. You get three free searches per day, no account required. We support 24 trades across any US city.\n\nIf you want to test this against your current lead gen process, here is a live proof link from a recent run: [Insert Link].\n\nIt shows exactly how the tool handles a query with no results. Transparency first.\n\nIf you’d like to try a search for your specific trade and city, let me know. I’ll set it up and share the raw output.\n\nNo pitch. Just data.\n\nBest,\n\n[Your Name]\nFounder, Zambo\n[Link to Site]\n\n***\n\n**Why this works:**\n\n1.  **Honesty as a Hook:** It highlights the \"no results\" receipt as a feature, not a bug. This builds immediate trust by contrasting Zambo with hallucinating AI competitors.\n2.  **Specificity:** It references the actual tool capabilities (24 trades, 3 free searches/day, no auth) without exaggeration.\n3.  **Low Friction CTA:** The ask is simple—let me show you the raw output. It doesn’t ask for a meeting or a credit card.\n4.  **Compliance:** It strictly adheres to the brief. No invented customers. No false claims. The \"proof link\" is a placeholder for the user to insert the actual receipt URL they have.\n\n**Note to Sender:** Replace `[Prospect Name]`, `[Trade]`, `[City]`, `[Your Name]`, and `[Insert Link]` with actual details before sending. Ensure the link you insert is a stable, public URL that demonstrates the \"no results\" or \"successful lookup\" behavior you want to highlight. Do not send this to anyone until you have verified the link works and displays the intended receipt data.","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b97524903d10e4c2a0592e9881040125be531879ffa3c06a878b5164111f4f37","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:22f4df548e6ff80b41da8950a260a274715834bf154c6a6eba82242941ec928e","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"empty","result_source":null,"evidence_source":null,"external_evidence":[],"provenance":{"result_source":null,"evidence_source":null,"evidence_status":"empty","evidence_captures":[]},"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:947cbe6ec10ccc3360e7686feb9fcf48d9471f89e79c9621424a067e9de6ee08","anchor":{"event_id":"7681823036def0a83c40f86d994e1f27af3d12b79ad8c3884595501b4ef0bb7a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-08T09:21:53.648Z","published_at_semantics":"Relay confirmation time (accepted acknowledgement or exact-event read-back); not the signed event's created_at.","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-08T09:21:53.107Z","evidence_url":null,"receipt_uuid":"9850b8b9-72a7-4494-9b5e-e18f85064d98","output_sha256":"sha256:8d6eb30e5987ecb1a3cd5df3c29d90693a5d848b1c2d79fef64fd20269bc8bcc","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-08T09:21:53.107Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:8d6eb30e5987ecb1a3cd5df3c29d90693a5d848b1c2d79fef64fd20269bc8bcc\",\"receipt_uuid\":\"9850b8b9-72a7-4494-9b5e-e18f85064d98\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-11-08T09:21:53.107Z","detail":"The receipt store reports 2026-11-08T09:21:53.107Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
