Email Debugging with Environment Variables in Power Platform

Testing email workflows in Power Platform, especially in production, requires a safe method to avoid sending test emails to real users. Here's a quick approach using environment variables to direct emails to a test inbox when debugging.

Step 1: Set Up Environment Variables

In Power Apps, create two environment variables:

• eVar_Debug (Yes/No) : set to "Yes" to enable debugging mode
• eVar_DebugEmails (Text) : enter a test email address

eVar_Debug controls whether emails are sent to test (eVar_DebugEmails) or real recipients.

Step 2: Add Conditional Logic in Power Automate

In your Power Automate flow, add a condition to check if eVar_Debug is equal to "true".

• If Yes : send emails to eVar_DebugEmails
• If No : send emails to the real recipient

This condition allows emails to be directed based on debug mode.

Why This Approach?

With this setup, you can:

• Safely test email flows in both development and production environments
• Easily toggle debug mode by updating eVar_Debug

Simple, effective, and perfect for debugging email flows without impacting real users.
