{ "name": "Lumeor | Email to Asana task", "nodes": [ { "parameters": { "content": "## Email to task (Gmail, Claude, Asana)\n\n**What it does**\nWatches a Gmail label such as \"To task\". Each new message has quoted history, signatures and footers stripped, then Claude labels it (new request, update, informational, automated, other) and extracts a verb-first title, description, requester, due date and priority. Requests become Asana tasks with a link back to the email; replies on a thread that already has a task become a comment instead of a duplicate. A Google Sheet stores thread-to-task mappings, and the email gets a \"captured\" label. Failures go to Slack.\n\n**Setup**\n1. Credentials: Gmail OAuth2, Anthropic (API key), Asana, Google Sheets, Slack.\n2. In Gmail create two labels, for example \"To task\" and \"Task captured\". Put their label IDs in REPLACE_WITH_TO_TASK_LABEL_ID (trigger) and REPLACE_WITH_CAPTURED_LABEL_ID.\n3. Create a Google Sheet with a tab named Threads and header row: thread_id, task_id, task_url, subject, from_address, created_at. Replace REPLACE_WITH_SHEET_ID.\n4. In *Parse and route*, fill DOMAIN_PROJECTS, DEFAULT_PROJECT (a \"Needs review\" project) and PEOPLE. Set REPLACE_WITH_ASANA_WORKSPACE_ID and REPLACE_WITH_SLACK_EXCEPTIONS_CHANNEL_ID.\n5. Run for two weeks with every task going to the Needs review project before routing to client projects.\n\n**Notes**\n- Model: claude-opus-5-5 with structured outputs. claude-haiku-5-5 is a cheaper option for high-volume, simple classification such as the request/not-request decision.\n\nTemplate by Lumeor Studio, https://www.lumeor.studio/guides/ai-email-to-task-automation/", "height": 780, "width": 560, "color": 5 }, "id": "07a19180-c2ee-4171-b315-eb69160c8383", "name": "About this template", "type": "n8n-nodes-base.stickyNote", "typeVersion": 1, "position": [ -760, 0 ] }, { "parameters": { "pollTimes": { "item": [ { "mode": "everyMinute" } ] }, "simple": false, "filters": { "labelIds": [ "REPLACE_WITH_TO_TASK_LABEL_ID" ], "readStatus": "both" }, "options": {} }, "id": "7b7911b6-1642-4bd3-9676-ed375c107f5d", "name": "Gmail: To task label", "type": "n8n-nodes-base.gmailTrigger", "typeVersion": 1.2, "position": [ 0, 300 ], "credentials": { "gmailOAuth2": { "id": "", "name": "Gmail account" } } }, { "parameters": { "mode": "runOnceForAllItems", "language": "javaScript", "jsCode": "// Removes quoted history, signatures and footers so the model reads only what\n// the sender wrote in this message.
