n8n Workflow: Email Analysis and Notification

This n8n workflow automates the process of receiving emails, extracting their content, and potentially sending notifications based on the email's characteristics. While the directory name suggests integration with "Sublime Security" and rule-based analysis, the provided JSON primarily defines a flow for email reception, basic processing, and notification via Slack.

What it does

This workflow simplifies email monitoring and notification by:

1. Listening for New Emails: It continuously checks a configured IMAP email account for new incoming emails.
2. Converting Email Attachments (if any): If an email contains binary data (like attachments), it converts this data to a usable format.
3. Processing Email Content: It processes the received email, likely extracting key information from its body or headers.
4. Conditional Logic (Placeholder): It includes an "If" node, suggesting that further actions can be conditionally triggered based on the email's content or metadata.
5. Preparing Data for Slack: It uses an "Edit Fields" node to prepare and format the relevant email data for a Slack message.
6. Sending Slack Notifications: It sends a notification to a specified Slack channel, likely containing details about the received email.

Prerequisites/Requirements

To use this workflow, you will need:

• IMAP Email Account: Access to an IMAP-enabled email account that n8n can monitor.
• IMAP Credentials: The necessary credentials (host, port, username, password) for your IMAP email account.
• Slack Account: A Slack workspace and a channel where you want to receive notifications.
• Slack API Token/Webhook: A Slack API token or a webhook URL to allow n8n to post messages to your Slack channel.

Setup/Usage

1. Import the Workflow:
   • Open your n8n instance.
   • Click on "Workflows" in the left sidebar.
   • Click "New" or "Import from JSON" and paste the provided JSON code.
2. Configure Credentials:
   • Email Trigger (IMAP): Click on the "Email Trigger (IMAP)" node. You will need to create or select an IMAP credential. Provide your IMAP server details (host, port, username, password).
   • Slack: Click on the "Slack" node. You will need to create or select a Slack credential. This typically involves providing an OAuth access token or a webhook URL.
3. Configure Nodes:
   • Email Trigger (IMAP): Specify the folder to watch (e.g., "INBOX") and the polling interval.
   • If: Currently, the "If" node is present but its conditions are not defined in the JSON. You will need to configure the conditions based on what you want to filter or analyze in the incoming emails (e.g., {{ $json.subject.includes('urgent') }} to check for "urgent" in the subject).
   • Edit Fields: Review the "Edit Fields" node to ensure it extracts and formats the email data as you desire for the Slack message. You might want to include fields like from, subject, date, and a snippet of the text body.
   • Slack: Configure the "Channel" where the notification should be sent and customize the "Text" of the message using expressions to include data from the previous nodes (e.g., New email from {{ $json.from }} with subject: {{ $json.subject }}).
4. Activate the Workflow: Once configured, save and activate the workflow. It will start monitoring your email account based on the defined schedule.
