📩 Feedback Genius Messages Not Appearing in Seller Central: Attachments & Sending Email Guide | Seller Labs: Amazon Seller Tools Help Center

🧭 Overview

If your message appears as “Sent” in Feedback Genius but doesn't show up in Amazon Seller Central, it’s likely due to one of the following:

A corrupted or oversized attachment, especially a PDF
An unauthorized “Sending Email” address that isn't approved in Seller Central

This article walks you through how to identify and fix both issues.

📎 Part 1: Fixing Attachment Issues

⚠️ Problem

Amazon may block messages with corrupted attachments—even if Feedback Genius displays them as “Sent.” This happens silently, meaning there are no visible errors unless you investigate manually.

🔍 How to Confirm

Send a test message to yourself:

If the message fails to deliver, or
You cannot open/download the attachment

Then the file is likely corrupt or incompatible.

🛠 How to Fix

Navigate to Review and Edit Message in Feedback Genius.
Scroll to the Attachments section (under the text editor).
Click the trash can icon to remove the attachment.
Click Save & Send Test or Save & Complete.
Re-upload the attachment (ideally an optimized version).
Monitor the message in your Sent Messages tab in Seller Central.

Resize Images: picresize.com

These tools compress files without noticeably affecting quality and help avoid delivery blocks.

📧 Part 2: Verifying Your “Approved Sending Email” Address

⚠️ Problem

If your Sending Email in Feedback Genius does not match an Amazon-approved Alternate Address, Amazon may prevent your message from appearing—even if it’s technically delivered.

📍 Important Notes

Each Amazon marketplace (e.g., US, UK, CA) may have its own list of approved Alternate Addresses.
The “Sending Email” is not shown to buyers—Amazon masks it with your store name and a cryptic email (e.g., asdfghjklmqwertyuip@marketplace.amazon.com).

🔄 How to Fix

Log in to Seller Central, go to the Messages tab.
From the Links section on the right, click Messaging Permissions.
Verify or add your “Sending Email” under Alternate Addresses for each marketplace.

Please refer to these detailed instructions!

🛠 How to Update in Feedback Genius

Click on Custom Messages in the top-left hamburger menu.
Find the relevant message and click the pencil icon in the “Sending Email” column.
Choose or enter an approved email address.
A popup will appear—review it and click Save to apply changes.
