Description

Emails with ESG reports should not sit in the inbox. This automation watches your Gmail for messages about CSRD reporting, reads the attached XHTML file, and sends a clear audit summary back to the sender. It helps sustainability and finance teams close the loop fast without manual review.

Here is how it works. A Gmail trigger checks new mail and an If filter looks for a subject match like CSRD Reporting. The attachment is downloaded, converted from binary to text, and parsed by code to inspect tags and content. An AI Agent with an OpenAI chat model turns the findings into a short email using a structured format for the subject and body. The reply is posted in the same thread so the sender gets feedback right away.

You need Gmail and OpenAI access, plus n8n credentials for both. Set the subject keyword you want, adjust the prompt tone, and choose the output fields you plan to send. Teams that handle supplier ESG files or weekly disclosures can cut review time from about 30 minutes to under 3 minutes and keep a consistent response style across the inbox.

Video Tutorial

What this workflow does?

  • Gmail trigger polls for new messages and starts the flow
  • If node filters by subject text so only CSRD related emails move forward
  • Gmail attachment download grabs the XHTML file from the message thread
  • Extract from file converts the XHTML from binary to readable text
  • Code nodes parse HTML content and build structured audit results
  • OpenAI chat model generates a clear summary based on the audit
  • Structured output parser enforces subject and body fields for clean formatting
  • Gmail reply posts the summary back to the original sender in the same thread

What are the benefits?

  • Reduce manual review from 30 minutes to under 3 minutes per report
  • Automate up to 90% of inbox triage by filtering only relevant emails
  • Keep responses consistent with structured subject and body fields
  • Handle 5 to 10 times more ESG reports without adding staff
  • Connect Gmail and OpenAI to deliver fast, thread-safe replies

How to set this up?

  1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
  2. You'll need accounts with Gmail and OpenAI. See the Tools Required section above for links to create accounts with these services.
  3. Open the Gmail Trigger node, click the credential dropdown, select Create new credential, and follow the on screen steps to connect your Gmail account with OAuth2. Choose the mailbox and set polling to every minute.
  4. In the If node, set the condition to check the email subject contains your chosen keyword such as CSRD Reporting. Adjust case sensitivity if needed.
  5. Open the Gmail Download Attachment node and confirm Download Attachments is enabled. Keep the Message ID expression so it references the incoming email.
  6. Check the HTML from binary node and confirm the binary property name matches the first attachment such as attachment_0.
  7. Open the Extract the HTML code node and verify it maps the binary text into a field named xhtml_content for the next step.
  8. Open the Check the format code node and review the tag parsing logic. Add or remove tags based on your XHTML structure to improve the audit results.
  9. Open the OpenAI Chat Model node, click Create new credential, and paste your OpenAI API key from your OpenAI account API page. Select a supported model.
  10. In the AI Agent node, link the chat model and the structured output parser. Edit the system message to match your brand voice and email style.
  11. Open the Structured Output Parser and confirm the schema includes subject and body fields. Keep field names in sync with the Gmail Reply node.
  12. In the Gmail Reply node, keep the message ID expression so replies stay in the original thread. Set Email Type to text or HTML as needed.
  13. Send a test email to your Gmail inbox with the keyword in the subject and an XHTML attachment. Check the n8n execution log for a successful run and confirm the reply in Gmail.
  14. Troubleshoot: if no attachment is found, confirm the binary property name. If parsing fails, update the tag list or HTML selectors. If the AI step errors, verify your OpenAI API key and model name.

Automate Gmail Flight Price Alerts
Get daily flight deal alerts sent straight to your inbox. It watches your route and only emails you when the ticket price is at or below your target. Ideal for travel coordinators, office managers, and anyone booking company trips. Each morning a schedule runs, loads your origin and destination, and fetches airline data from Amadeus to show real carrier names. A code step creates future dates to search, by default 7 and 14 days out. The system loops through each date and calls the Amadeus flight offers API, pausing briefly between calls to respect limits. Results are merged and cleaned, key fields like price, time, duration, and carriers are extracted, and only fares under your price move forward to Gmail for a clear, easy to read alert. Set your airports in the FromTo node, tweak the day offsets in Get Dates, and choose your price target in the Under Price filter. Expect to replace manual checks with one scheduled run and act quickly when good fares show up. Most teams save 20 to 30 minutes a day and avoid missing short lived price drops. Great for controlling travel costs without monitoring sites all day.

Automate Gmail to Todoist Task Management
Turn important emails into clear Todoist tasks without copy and paste. The flow watches your Gmail inbox, builds a task when a new or starred email appears, and adds a short summary with next steps and a draft reply. It also closes the task when you remove the star from the email, so your list stays clean. On a schedule or when new mail arrives, it reads unread and starred messages from Gmail. New unread items can be marked as read and starred to show they need action. The flow checks open Todoist tasks and matches them to email subjects. If no match exists, it pulls the full message, sends it to OpenAI to create structured fields content, description, actions, and answer, then creates a Todoist task with that detail. A guard step checks the AI output before creating the task. Another path detects emails that lost the star and closes the linked Todoist task. To run it, connect Gmail, your email IMAP inbox, Todoist, and an OpenAI key. Pick the Todoist project where new tasks should go and adjust the optional read and star actions if you prefer different inbox rules. Teams that triage support or sales email will cut manual entry and miss fewer follow ups, often saving an hour a day.

Automate Gmail Spam Cleanup Alerts
Keep your Gmail inbox clean without constant manual sorting. The flow reviews older messages, removes marketing and spam, and sends you quick updates in Telegram. It suits busy teams and solo users who get too much promo mail and want less noise. It runs on demand from n8n. Emails are pulled from Gmail in 14 day chunks using a smart date filter, so large inboxes are handled in manageable windows. Google Gemini scores each email with decimal confidence for unwanted, marketing, and spam, and returns a short reason plus the email ID and sender. If the scores signal unwanted content, the message is deleted and a Telegram alert shows the sender and reason. If it looks safe, a keep label is added in Gmail and you receive a skip notice. AI errors are also posted to Telegram, so you always know what happened. You need Gmail access, a Telegram bot, and a Google Gemini API key. Set your Telegram chat ID and tune the confidence thresholds to match your risk level. Expect weekly inbox cleanup time to drop from hours to minutes while staying in control through clear alerts. You can add a schedule later with a Cron trigger to run this clean up daily.
