Automated Gmail Labeling and Brainstorming This template can be used to automatically label your incoming Gmail messages with AI and to build a knowledge graph from the emails tagged with a specific label to brainstorm new ideas based on them. You can also get notified about the emails with the most important labels via Telegram as well as receive new ideas as you are building a knowledge graph of incoming messages. The idea generation is based on the InfraNodus knowledge graph content gap detection algorithm, which builds a network from your content and then finds a blind spot and uses AI to generate an interesting research question or idea that can be used to bridge this gap. Why it works so well? Think of all the business emails you receive that bypass the spam filters. Probably, they are personalized to you already. Now imagine if you build a knowledge graph from them for over a month. You will then have a ideation device based on your interests and marketing profile. Now, if you identify the gaps inside and generate interesting research questions based on them, you will come up with new interesting ideas that will be relevant (because they touch on the topics that matter to you), but novel, because they bridge them in new ways. What is it useful for? - Automate Gmail incoming message labeling with the new Classifier n8n node — much more advanced than the default Gmail labeling rules. - Get notified via Telegram (or a messenger of your choice) about the most important messages and be sure not to miss anything important. - Keep the messages with a certain label saved into knowledge graph for brainstorming and ideation. - Every time a new message of this category comes in, it's added into the graph, changing its structure, a new idea is generated. So instead of looking at each specific offer, you now use them to generate insights for you. How it works - Step 1: This template can is triggered automatically when a new Gmail message arrives. Note: you need to connect your Gmail account here in this node - Step 2: We use the new n8n AI Classifier Node to classify your email based on its content. You might need to update to n8n 1.94 version to make it work. Note: we like to use Gemini AI for that classifier as it's the same company as Gmail, so should be safe with data - Step 3: After classifying the message, we label the message with the appropriate label. Note: you need to create the labels before in your Gmail account - Step 4: For a certain category (e.g. "Business" you format the message and save it into your InfraNodus graph. Note: specify your InfraNodus API here and choose the name of the graph. It will use the InfraNodus HTTP graphAndEntries endpoint and save your data to an InfraNodus graph. By default, we save the text knowledge graph using the contextSettings parameters (it will only build a text graph of the content), but you can take an alternative setting from this InfraNodus HTTP node's settings and create a social knowledge graph, that will also show email senders in the graph itself. - Step 5 (optional): Generate an interesting insight question with the graphAndAdvice endpoint) of InfraNodus. - Step 6 (optional): Then send this insight via Telegram to a chat. - Step 7 (optional): Link some important labels to the second Telegram notification node, so you receive important messages for specified labels. - Step 8 (optional): Send a Telegram notification We use Telegram, because it takes only 30 seconds to set up a bot with an API (send /newbot to @botfather, unlike Discord or Slack, which is long and cumbersome to set up. You can also attach a Gmail send node and generate an email instead. How to use You need an InfraNodus GraphRAG API account and key to use this workflow. - Create an InfraNodus account or log in. - Get the API key at and create a Bearer authorization key for the InfraNodus HTTP nodes. - Add this Authorization code in Steps 4 and 5 of the workflow. - Come up with the name of the graph and change it in the HTTP InfraNodus nodes in the steps 4 and 5 and also in the Telegram node in Step 6 that sends a link to the graph. - For additional text processing / idea generation settings you can use in the HTTP InfraNodus nodes, see the InfraNodus access points page. For example, in Step 4 you can change the text processing settings to build a social knowledge graph (settings are available in the Node's Notes section) and in Step 5 you can change the requestMode from question to idea to receive business ideas instead. - Authorize your Gmail account for Steps 2, 3, 7 and 8 Gmail nodes. The easiest way to set it up is to open a free Google Console API account and to create an OAuth access point for n8n. You can then reuse it with other Google services like Google Sheets, Drive, etc. So it's a useful thing to have in general. - Set up the Gemini AI API key using the instructions in the Step 2 Gemini AI classification node. - Set up the Telegram node bot for the Step 8. It takes only 30 seconds: just go to @botfather and type in /newbot and you'll have an API key ready. To get the conversation ID, follow the n8n / Telegram instructions in the node itself. - Once everything is ready, try to run the default automated workflow to test if everything works well. Requirements - An InfraNodus account and API key - An Google Cloud API OAuth client and key for Gmail access - A Gemini AI API key - A Telegram bot API key - n8n version 1.94 and higher (for Text Classification AI node to work) Customizing this workflow Check our other n8n workflows at for useful content gap analysis, expert panel, and marketing, and research workflows that utilize GraphRAG for better AI generation.
