What our clients say
Edit every field Amazon lets you change
Not just the title, bullets and description. Material, unit count, country of origin, package dimensions, batteries: every attribute Amazon allows for your product type, checked against Amazon’s own rules before you save it. In the platform from the Guru plan; from your assistant, through the MCP, on Business and Master.
All your product’s attributes, editable in one place
- Every attribute of the product typeThe Properties tab shows every field Amazon allows for that product type and marketplace, each with the right control: Amazon’s own options in a list, numbers, long text with a character counter. Labels appear in your language.
- Checked before you saveEach change is checked against Amazon’s rules for that product type and marketplace: length, format, allowed values and fields that go together. Say the product includes batteries and Epinium tells you which battery fields are still missing, and takes you to them.
- Seller Central and Vendor CentralWorks for Seller and Vendor products. Changes stay pending until you press Publish, as always.
Find out why a listing is inactive or rejected, and fix it
- Amazon’s problems, on the fieldThe problems Amazon already reports on a product show next to the field that causes them, and the side index counts them by group. Many inactive or suppressed listings come down to one missing or invalid attribute: now you see which one.
- Fixed on the same screenCorrect the field, save it as pending and publish. Properties will not save a field that still breaks a rule, so what you publish is something Amazon can accept.
- The same checks everywhereQuick edit, bulk edit, AI generation and tasks use the same checks. A change that would break a rule is not saved, and you see why.
See when Amazon accepts each change
- Publications panelEvery time you press Publish, the Publications panel shows its progress country by country, so you know whether Amazon is still processing it or has already accepted it.
- Rejections with their reasonIf Amazon rejects a change, you see the field and Amazon’s message, with a link to the product to fix it.
- From your assistant, in bulkOn Business and Master, ask Claude or ChatGPT to change many listings from a spreadsheet through the Epinium MCP. Every row is checked against Amazon’s rules before anything is saved.

ExploreFrequently Asked Questions
Which product fields can I edit, and on which plan?
Every attribute Amazon allows for your product type and marketplace, not just the title, bullets and description, for Seller and Vendor products. Each change is checked against Amazon’s rules before it is saved. You edit them in the platform from the Guru plan; changing many listings from a spreadsheet through your assistant and the Epinium MCP needs Business or Master.
Why is my Amazon listing inactive, and can Epinium fix it?
Often because of one attribute that is missing or breaks a rule for its category. The Properties tab shows the problems Amazon reports next to the field that causes them, so you can correct it, save it and publish. You then follow it in the Publications panel until Amazon accepts it. Problems outside the product data, such as pricing or documents Amazon asks for, are still solved in Seller Central.
Which sales channels does Epinium connect to for my catalog?
Amazon Seller Central and Vendor Central are deeply integrated: Epinium pulls live catalog data and pushes approved content straight to your listings, for both 1P and 3P. Shopify and WooCommerce are connected: your assistant works with your products and inventory live through Epinium MCP, and the new content is written for you to apply. For other marketplaces and stores, the CMO AI playbooks work with your exports. Selling on Amazon? See our Amazon listing tool.
Can Epinium handle multilingual catalogs?
Yes. Epinium supports content optimisation in English, Spanish, Italian, German and French, with marketplace-specific keyword data for each language and region.
How does AI listing optimisation work?
Epinium analyses your current listing, your competitors' listings and search volume data for relevant keywords. It then generates optimised titles and bullets that follow the marketplace's content guidelines, which you review and publish.
Does it work for Vendor Central accounts?
Yes. Epinium supports both Seller Central and Vendor Central accounts, including 1P and 3P catalog management.
