3Dsellers Listings Automations — Complete Guide

Listings Automations let you automatically update and optimize your marketplace listings based on rules you define. Instead of adjusting inventory, templates or listing content manually every time something changes, you set a trigger plus optional filters, choose one or more actions, and 3Dsellers does the rest.

You will find Automations here:
Listings & Products → Listings Manager → Automations

This article is the overview. Each action has its own article with its fields and gotchas, linked below.

Triggers: when an automation runs

Listings Automations have three triggers.

🆕 Item Listed - runs when a new listing is created.
📦 Warehouse Updated - runs when a warehouse quantity changes.
⏰ Run By Schedule - runs on a schedule you set, rather than in response to an event.

The actions available to you depend on the trigger and the channel you choose. If you select actions and then change the trigger, any action that is not allowed on the new trigger is removed from your selection automatically.

Actions restricted to Run By Schedule only: Re-list Item, Create Draft When Sold Out.
Actions restricted to Warehouse Updated only: Send Alert.

What Listings Automations cannot do

A few things people often look for are not available here:

There is no "listing ended" trigger, so you cannot run an automation, or send a notification, when a listing is ended. There is also no way to distinguish a listing you ended manually from one that ended on its own.
There is no trigger for an order or a sale. Order-based rules live in Orders Manager automations, and buyer messaging lives in Marketing → Auto Messages.
Send Email and Send Alert are internal notifications only. They never reach buyers.

If you need something that is not here, please tell us. Requests go to the product team directly: Submit an automation feature request.

Automations in other parts of 3Dsellers

Listings Automations act on live listings. Other modules have their own automations with their own triggers:

Products Catalog - triggers on Product Created, Inventory Updated, catalog tag added or removed, and schedule. Actions include editing attributes and categories, linking or unlinking listings, AI product content, publishing products to a channel, and setting a listing out of stock.
Orders Manager - triggers when an order is received and paid, received and unpaid, or cancelled. Actions include sending an email, sending an eBay invoice, order tags and notes, and creating a Shopify order.
Helpdesk - triggers on a conversation starting, a new message, or a conversation tag change. Actions include setting ticket status and type, assigning a teammate, tagging, and marking read, unread or starred.

The Automations page

Automations tab

Your list of rules. Filter narrows the list, New Automation creates a rule, Suggest Automations sends us an idea for a new one.

Logs tab

A history of what actually ran: date, item, automation name, trigger, actions performed and status. Search by Item ID to check a specific listing. This is the first place to look when an automation does not seem to be working.

Creating a new automation

1. Name (required)

Give it a clear name so you can find it in the Logs later, for example "Auto-SEO on new listings".

2. Notes (optional)

Internal notes on what it does or who asked for it.

3. Channel

Which marketplace the automation applies to. Currently supported: eBay, Shopify, Amazon, Etsy, WooCommerce, Walmart and TikTok. Many actions are eBay only, as noted in the action list above.

4. Trigger

Pick one of the three triggers above.

5. Filters (optional)

Filters narrow which listings are eligible before actions run. Fields include title, SKU, variation SKU, tag, has GPSR, item with variations, best offer enabled, images count, SEO, vehicle compatibility, MPN, category, publish date, policies, price, quantity sold and more. You can combine several.

Filters are the main protection against over-automation. Use them.

6. When (condition)

Only available with the Warehouse Updated trigger. Example: warehouse inventory greater than / equals / less than 0. It decides whether the automation continues for that item.

7. Actions

Choose one or more actions. See the action list above for what each one does.

8. Save options

Cancel - discard changes.
Save - save without activating, so you can review it first.
Save and Activate - turn it on immediately.

⚠️ Automations only run when Active.

Common use cases

1. Auto-optimise new listings

Trigger: Item Listed
Actions: Generate AI Listing Content + Apply Listing Designer Template
Result: every new listing publishes with optimised copy and your branded layout.

2. Avoid out-of-stock listings

Trigger: Warehouse Updated
When: warehouse inventory equals 0
Actions: Update Warehouse Inventory (set to 100) + Update eBay Inventory (display 3)
Result: items are restocked automatically and the listing shows a low quantity rather than your real stock.

3. Fix listing quality problems as they appear

Trigger: Item Listed
Filter: SEO is not present
Action: Generate AI Listing Content, SEO fields selected
Result: gaps are filled the moment a listing is created, and listings that already have SEO are left alone.

4. Segment by category

Trigger: Warehouse Updated
Filter: Category = "Athletic Shoes"
Condition: warehouse inventory greater than 1
Action: Update eBay Inventory or Apply Listing Designer Template
Result: only the targeted product group is touched.

5. Cross-list new listings to a second account

Trigger: Item Listed
Filter: Tag = "cross-list"
Action: Copy to Drafts
Result: every new tagged listing is duplicated as a draft on your second account, ready to review and publish.

Best practices

Start simple. One trigger, one action, then expand.
Save without activating first, review the setup, then activate.
Test on a few listings using a tag filter before letting an automation run on everything.
Name automations clearly, it makes the Logs readable.
Review Logs weekly.
Avoid conflicting rules. Two automations with opposite actions create ping-pong updates.

FAQs

Do automations change my listings without asking?
Yes. Once active, they update listings whenever conditions match. That is why filters and the When condition matter.

Can I add more than one action to a single automation?
Yes, you can stack actions, as long as each is allowed on the trigger and channel you chose.

Why did an action disappear when I changed the trigger?
That action is restricted to the previous trigger, so it was removed from your selection. See the trigger restrictions above.

How do I know an automation ran?
Check the Logs tab. A green tick means it ran without errors.

Can I get an email when a listing is ended?
No. There is no ended-listing trigger today. Please submit a feature request so it is counted.

Troubleshooting

The automation runs but nothing changes

An action may be missing a required value, for example a blank quantity.
The When condition may not be met even though the trigger fired.
For price automations, the listing needs both a floor and a ceiling price, and the price may already be at the bound.

The automation never appears in the Logs

It is not Active.
No listings match the filters.
The trigger never fires for your workflow, for example Item Listed on an account where you are not creating new listings.

Unexpected updates

Check for another automation affecting the same listings.
Narrow the set with filters or tags.
