Monitor Elastic Email Credits with Slack Alerts in n8n

Never Run Out of Email Credits Again

This n8n workflow automatically monitors your Elastic Email subaccounts and sends instant Slack alerts when credit balances drop below your threshold. Stop unexpected email campaign failures and maintain seamless communication with your audience through proactive credit monitoring.

What This Workflow Does

The workflow runs daily on a scheduled basis, executing these key steps:

• Connects to the Elastic Email REST API to retrieve all subaccount data
• Filters accounts based on your configurable minimum credit threshold (default: 100 credits)
• Sends detailed Slack notifications listing email addresses and current credit balances for low-balance accounts
• Captures and reports API errors separately to Slack for complete monitoring coverage
• Operates hands-free once configured, providing daily peace of mind

Use Cases

Perfect for marketing teams running multiple email campaigns across different Elastic Email subaccounts who need early warning before credits expire. Email service providers managing client accounts benefit from automated monitoring to prevent service disruptions. Development teams with automated email systems can avoid critical notification failures. Digital agencies handling numerous client email accounts gain centralized credit oversight without manual checking.

Technical Details

Built using essential n8n nodes including HTTP Request for Elastic Email API integration, Slack node for notifications, Filter node for credit threshold logic, Code node for data processing, and Set node for configuration management. The workflow uses Custom Auth credentials for secure Elastic Email API access and requires a Slack workspace with bot permissions.

Setup involves configuring your minimum credit threshold in the Config node and adding your Elastic Email API key through Custom Auth credentials. The HTTP Request node handles API calls while error handling ensures you're notified of both low credits and technical issues.

This automation workflow transforms manual credit checking into an automated early warning system, helping n8n users maintain reliable email operations across multiple Elastic Email accounts.
