Overview

Amazon flags a listing with error code 990100 when it discovers an email address embedded in any customer‑facing attribute such as the title, bullet points, or description. The violation stops the product from appearing in search results until the offending text is removed, making it a critical compliance issue for sellers who rely on uninterrupted visibility.

Key Points

• Email addresses are disallowed in any public field — Whether placed in the product title, bullet list, or description, an email address triggers error 990100.
• The error pinpoints the exact attribute — Amazon’s report cites the specific field (e.g., “Bullet 2”) and the exact email string (e.g., “[email protected]”) so sellers can locate the problem instantly.
• Phone numbers and external URLs are also prohibited — Contact details that could divert shoppers away from Amazon, such as “+1‑800‑555‑1234” or “www.mybrand.com,” generate the same compliance block.
• Promotional claims are treated similarly — Phrases like “free shipping worldwide” or “100 % quality guarantee” violate Amazon’s style rules and are often flagged together with contact‑info violations.
• A feed resubmission is mandatory — Simply editing the listing in Seller Central does not clear the error; the corrected product feed must be uploaded again for Amazon to re‑process the data.
• Bulk‑upload errors can affect many ASINs — A single spreadsheet template that contains an email address in a reusable field can cause the same error across dozens or hundreds of listings.

How to Fix Error 990100

1. Download the processing summary report — In Seller Central, open the “Feed Processing Report” for the recent upload; the report will list each ASIN, the attribute name, and the offending email address (e.g., “Bullet 1 – [email protected]”).
2. Remove the email address from the identified field — Open the original feed file, locate the row and column shown in the report, and delete the entire email string. For example, change “Fast shipping – contact [email protected]” to “Fast shipping.”
