💡 Challenge
Automated notification emails often arrive with no clue which Power Automate flow or system triggered them, slowing support and audits.
✅ Solution
Embed a unique identifier in the sender address using plus addressing (user+tag@domain.com). The email itself now reveals its origin.
🔧 How It’s Done
Here’s how to do it:
- Choose a clear tag, e.g.
guest-managementorinvoice-processing
🔸 Example tag:guest-management - Configure the sending system or Cloud Flow to use the address
user+tag@company.com
🔸marcel.lehmann+guestmanagement@company.com - Gmail / Google Workspace works the same way
🔸marcel.lehmann+newsletter@gmail.com - (Optional) Create inbox rules or labels that sort or flag messages automatically.
🎉 Result
Every incoming email clearly shows which workflow generated it, cutting troubleshooting time to seconds and simplifying compliance reports.
🌟 Key Advantages
🔸 Immediate source identification
🔸 Faster troubleshooting for IT and support
🔸 Simplified audit and compliance tracking
🔸 Zero extra licensing or infrastructure cost
🛠️ FAQ
1. Does plus addressing survive corporate mail gateways?
Most modern gateways keep everything before “@” intact; only rare legacy filters strip the tag. Test first.
2. Can I assign multiple tags to the same project?
Yes. Use addresses like projectX+finance@company.com and projectX+it@company.com to separate streams.
3. Are there security concerns?
Avoid including sensitive information in the tag; use generic labels or numeric IDs instead.
