# Supplier not synced - invalid email

This error message appears in the **Sync details** panel when a supplier cannot be synced to your ERP because its email address fails validation. The supplier is not synced, and the **Suppliers** row shows **Failed**.

## Cause

The email address on the supplier record is missing or not in a valid format, so the ERP rejects the record.

## Solution

1. Open the **Sync details** panel and note the affected suppliers (supplier name, tax number, external ID).
2. Use the **Go to [ERP]** link to open the supplier or vendor record in your accounting system.
3. Correct the email address so it is valid.
4. Return to Payhawk and run the sync again.
