Automate Weekly Marketing Reports with AI and Gmail

This n8n workflow automates the generation and delivery of weekly marketing reports by leveraging AI capabilities and integrating with Gmail. It simplifies the process of creating insightful summaries and distributing them to relevant stakeholders.

Description

This workflow is designed to streamline the creation and distribution of weekly marketing reports. It uses a scheduled trigger to initiate the process, an AI Agent to generate report content, and then sends the generated report via Gmail. The workflow is flexible, allowing for the use of either Anthropic (Claude AI) or OpenAI chat models for content generation.

What it does

  1. Triggers Weekly: The workflow is initiated on a defined schedule, ensuring that reports are generated consistently every week.
  2. Prepares Data (Placeholder): An "Edit Fields" node is included, which can be configured to prepare or structure any initial data needed for the AI agent to generate the report. (Currently, it's a generic "Set" node, ready for customization).
  3. Generates Report Content with AI: An "AI Agent" node, powered by either an "Anthropic Chat Model" (e.g., Claude AI) or an "OpenAI Chat Model," processes the input data (or a predefined prompt) to generate the marketing report content.
  4. Refines AI Output (Optional): A "Basic LLM Chain" node is available to further process or refine the output from the AI agent, if more complex text manipulation or summarization is required.
  5. Interacts with MCP Client (Placeholder): An "MCP Client Tool" node is present, suggesting potential integration with a Model Context Protocol client for advanced model interaction or data handling. (Currently, it's a generic "MCP Client Tool" node, ready for customization).
  6. Sends Report via Gmail: The final generated report content is then sent as an email using the Gmail node to the specified recipients.

Prerequisites/Requirements

  • n8n Instance: A running instance of n8n.
  • Gmail Account: A configured Gmail credential in n8n for sending emails.
  • AI Service Credential:
    • Anthropic Account/API Key: For using the "Anthropic Chat Model" (e.g., Claude AI).
    • OpenAI Account/API Key: For using the "OpenAI Chat Model."
  • Langchain Nodes: Ensure the @n8n/n8n-nodes-langchain package is installed and enabled in your n8n instance.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Set up your Gmail OAuth2 or API Key credential.
    • Set up your Anthropic or OpenAI API Key credential for the respective chat model nodes.
  3. Configure Schedule Trigger: Adjust the "Schedule Trigger" node to your desired weekly reporting frequency (e.g., every Monday at 9 AM).
  4. Customize "Edit Fields": Modify the "Edit Fields" (Set) node to provide any specific data or context that your AI agent needs to generate the report. This could be static text, data pulled from other sources, or variables.
  5. Configure AI Agent:
    • Select your preferred "Anthropic Chat Model" or "OpenAI Chat Model" within the "AI Agent" node.
    • Provide a detailed prompt to the "AI Agent" node, instructing it on what kind of marketing report to generate, what data to focus on, and the desired format.
  6. Configure Gmail:
    • In the "Gmail" node, specify the recipient email addresses, subject line, and map the output from the AI agent as the email body.
  7. Activate the Workflow: Once configured, activate the workflow to enable it to run automatically on schedule.

Automate Dutch Public Procurement Data Collection with TenderNed

TenderNed Public Procurement What This Workflow Does This workflow automates the collection of public procurement data from TenderNed (the official Dutch tender platform). It: Fetches the latest tender publications from the TenderNed API Retrieves detailed information in both XML and JSON formats for each tender Parses and extracts key information like organization names, titles, descriptions, and reference numbers Filters results based on your custom criteria Stores the data in a database for easy querying and analysis Setup Instructions This template comes with sticky notes providing step-by-step instructions in Dutch and various query options you can customize. Prerequisites TenderNed API Access - Register at TenderNed for API credentials Configuration Steps Set up TenderNed credentials: Add HTTP Basic Auth credentials with your TenderNed API username and password Apply these credentials to the three HTTP Request nodes: "Tenderned Publicaties" "Haal XML Details" "Haal JSON Details" Customize filters: Modify the "Filter op ..." node to match your specific requirements Examples: specific organizations, contract values, regions, etc. How It Works Step 1: Trigger The workflow can be triggered either manually for testing or automatically on a daily schedule. Step 2: Fetch Publications Makes an API call to TenderNed to retrieve a list of recent publications (up to 100 per request). Step 3: Process & Split Extracts the tender array from the response and splits it into individual items for processing. Step 4: Fetch Details For each tender, the workflow makes two parallel API calls: XML endpoint - Retrieves the complete tender documentation in XML format JSON endpoint - Fetches metadata including reference numbers and keywords Step 5: Parse & Merge Parses the XML data and merges it with the JSON metadata and batch information into a single data structure. Step 6: Extract Fields Maps the raw API data to clean, structured fields including: Publication ID and date Organization name Tender title and description Reference numbers (kenmerk, TED number) Step 7: Filter Applies your custom filter criteria to focus on relevant tenders only. Step 8: Store Inserts the processed data into your database for storage and future analysis. Customization Tips Modify API Parameters In the "Tenderned Publicaties" node, you can adjust: offset: Starting position for pagination size: Number of results per request (max 100) Add query parameters for date ranges, status filters, etc. Add More Fields Extend the "Splits Alle Velden" node to extract additional fields from the XML/JSON data, such as: Contract value estimates Deadline dates CPV codes (procurement classification) Contact information Integrate Notifications Add a Slack, Email, or Discord node after the filter to get notified about new matching tenders. Incremental Updates Modify the workflow to only fetch new tenders by: Storing the last execution timestamp Adding date filters to the API query Only processing publications newer than the last run Troubleshooting No data returned? Verify your TenderNed API credentials are correct Check that you have setup youre filter proper Need help setting this up or interested in a complete tender analysis solution?

πŸŽ“ How to transform unstructured email data into structured format with AI agent

This workflow automates the process of extracting structured, usable information from unstructured email messages across multiple platforms. It connects directly to Gmail, Outlook, and IMAP accounts, retrieves incoming emails, and sends their content to an AI-powered parsing agent built on OpenAI GPT models. The AI agent analyzes each email, identifies relevant details, and returns a clean JSON structure containing key fields: From – sender’s email address To – recipient’s email address Subject – email subject line Summary – short AI-generated summary of the email body The extracted information is then automatically inserted into an n8n Data Table, creating a structured database of email metadata and summaries ready for indexing, reporting, or integration with other tools. --- Key Benefits βœ… Full Automation: Eliminates manual reading and data entry from incoming emails. βœ… Multi-Source Integration: Handles data from different email providers seamlessly. βœ… AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. βœ… Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. βœ… Time Efficiency: Processes emails in real time, improving productivity and response speed. *βœ… Scalability: Easily extendable to handle additional sources or extract more data fields. --- How it works This workflow automates the transformation of unstructured email data into a structured, queryable format. It operates through a series of connected steps: Email Triggering: The workflow is initiated by one of three different email triggers (Gmail, Microsoft Outlook, or a generic IMAP account), which constantly monitor for new incoming emails. AI-Powered Parsing & Structuring: When a new email is detected, its raw, unstructured content is passed to a central "Parsing Agent." This agent uses a specified OpenAI language model to intelligently analyze the email text. Data Extraction & Standardization: Following a predefined system prompt, the AI agent extracts key information from the email, such as the sender, recipient, subject, and a generated summary. It then forces the output into a strict JSON structure using a "Structured Output Parser" node, ensuring data consistency. Data Storage: Finally, the clean, structured data (the from, to, subject, and summarize fields) is inserted as a new row into a specified n8n Data Table, creating a searchable and reportable database of email information. --- Set up steps To implement this workflow, follow these configuration steps: Prepare the Data Table: Create a new Data Table within n8n. Define the columns with the following names and string type: From, To, Subject, and Summary. Configure Email Credentials: Set up the credential connections for the email services you wish to use (Gmail OAuth2, Microsoft Outlook OAuth2, and/or IMAP). Ensure the accounts have the necessary permissions to read emails. Configure AI Model Credentials: Set up the OpenAI API credential with a valid API key. The workflow is configured to use the model, but this can be changed in the respective nodes if needed. Connect the Nodes: The workflow canvas is already correctly wired. Visually confirm that the email triggers are connected to the "Parsing Agent," which is connected to the "Insert row" (Data Table) node. Also, ensure the "OpenAI Chat Model" and "Structured Output Parser" are connected to the "Parsing Agent" as its AI model and output parser, respectively. Activate the Workflow: Save the workflow and toggle the "Active" switch to ON. The triggers will begin polling for new emails according to their schedule (e.g., every minute), and the automation will start processing incoming messages. --- Need help customizing?
