This one gives you workflow templates for automating Gmail tasks like extracting attachments and dumping them to Google Drive, auto-archiving invoices, and organizing client emails by project. Built on top of n8n patterns (7,800+ templates) and uses the Google Workspace MCP server for the actual API calls. You get four main templates out of the box: attachment manager, invoice archiver, client communication sorter, and email analytics. The implementation examples use both n8n JSON configs and Google Apps Script, so you can pick your stack. Honestly most useful if you're already dealing with high email volume and drowning in manual sorting, less so if you just need occasional automation.
