#PowerPlatformTip 139: 'Plus Address Tracking'

TL;DR: Add a tag to your sender address with plus addressing (user+tag@domain.com) so every automated email reveals which flow or system sent it, no extra licensing or infrastructure.

💡 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

1. Choose a clear tag

🔸 e.g. guest-management or invoice-processing.

2. Configure the sender address

🔸 Set the sending system or cloud flow to use user+tag@company.com, e.g. marcel.lehmann+guestmanagement@company.com.

3. Gmail / Google Workspace works the same way

🔸 marcel.lehmann+newsletter@gmail.com.

4. (Optional) Automate sorting

🔸 Create inbox rules or labels that flag or file the tagged 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

Q1: Does plus addressing survive corporate mail gateways?

Most modern gateways keep everything before “@” intact; only rare legacy filters strip the tag. Test first.

Q2: 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.

Q3: Are there security concerns?

Avoid putting sensitive information in the tag; use generic labels or numeric IDs instead.
