How to Upload 100 Designs to Amazon Merch in One Batch (2026 Walkthrough)

To upload designs to Amazon Merch in bulk, add all 100 to Merch Titans, either by dragging them into Easy Mode or by listing them in a spreadsheet, check the listing text, then press Start upload once. The app opens Amazon's create page in its own browser window and fills it in for each design, one after another, while you work on something else.

This walkthrough covers both routes as the app works today (checked Nov 6, 2026): what to set up once, what to prepare, what the app checks before it starts, and what it leaves to you.

Easy Mode or Spreadsheet: Which Route to Use

Rule of thumb: use Easy Mode if your designs don't have listings yet, and the spreadsheet if you already keep listings in a sheet. If you build listings in MyDesigns, a third way in is importing a folder from there, which arrives as a spreadsheet (see the import docs).

Before You Start: Set Up Once

You do these once, not per batch.

1. Install the app and sign in. It runs on Windows and Mac and uses the same account as merchtitans.com. See download and install.
2. Set up Amazon Merch. Open Amazon Merch in the sidebar. Under "Products and prices", choose "Use my Amazon publish settings" (marked Recommended) to use the products, prices and colours you saved on Amazon's own Create page with Save publish settings. Or choose "Choose them here" to pick from 37 products across .com, .co.uk, .de, .fr, .it, .es and .co.jp, with prices, colours, fit types and design size.
3. Choose what happens on upload. "Publish it" sends each listing to Amazon for review, then on sale. "Save as a draft" keeps it on your Amazon account until you publish it yourself. Under "Other languages", pick "Let Amazon translate" or "Use my text as written". The Amazon Merch docs cover every option.
4. Add other marketplaces if you sell there. Printify connects with an API token you paste in. Printful uses a token plus a sign-in to printful.com in the app's browser window. Redbubble uses a template you set up once, and Redbubble and TeePublic ask you to sign in, in a browser window, on the first upload. See the Printify, Printful, Redbubble and TeePublic docs.
5. Check Home. The "Where you sell" switches on Home decide which marketplaces appear on the upload screen. Leave the "I agree to assume all responsibilities and risks" box ticked, as it is by default: if it's unticked, the upload buttons do nothing and show no message.

Signing in to Amazon: on the first run, the Amazon window asks you to sign in by hand. "Stay signed in between uploads" is ticked by default and saves your session on this computer only. There's also automatic sign-in with a stored password, but the app itself labels it "Not recommended".

Route 1: Upload 100 Designs with Easy Mode

1. Add the designs. Open Easy Mode and drag all 100 files into "Add your designs". PNG or JPEG only. The app suggests a transparent background and 4500 pixels wide or more, but only checks that each file is a real PNG or JPEG.
2. Switch on Amazon Merch in step 2, plus anything else you sell on. Fix whatever a status card lists as missing, then go to Listings.
3. Set your rules for the AI. Open "AI instructions and bulk edit" and add custom instructions, such as your niche or words to avoid. If every listing uses the same brand, use bulk edit: choose Amazon Merch Brand, type the brand and click Add Text.
4. Click Write listings with AI. Tick the fields to fill (leave Brand unticked if you set it in step 3). Tick "Filter Amazon-restricted words from tags" to strip words like gift, birthday, glitter and gold from everything the AI writes. Then click Start Analysis.
5. Read and edit. Each box stops at its field's limit, such as 60 characters for the title and 256 for each bullet.
6. Check trademarks, if you choose to. Pick the Nice classes, read any flagged badges, and use Fix all trademarks or edit by hand. See the trademark check docs.
7. Pick Publish or Save as draft on the "On Amazon:" switch.
8. Click Start upload. If anything is missing, the app lists it, for example "Design 12: Amazon Merch Brand is required". Otherwise it opens the upload screen.
9. Tick the listings you want and press Start upload on that screen. This is the press that starts the run.

What 100 designs means in practice. The AI writes 12 designs at a time, so 100 designs go through in 9 rounds. The trademark check takes 10 at a time, so 10 rounds. Fix all trademarks works on 5 at a time, but only on the designs that were flagged. Easy Mode keeps the batch if you close the app partway, though trademark results need running again.

Tip: Export spreadsheet saves the whole batch as a spreadsheet, with a designs folder holding copies of the images. It's a backup, and you can upload it again later through Route 2. More in the Easy Mode docs and the AI listings docs.

Route 2: Upload 100 Designs from a Spreadsheet

1. Get the template. On Home, under "Use a spreadsheet", click "Get the blank template". It saves layout.xlsx with these headers: Image Path, Title, Description, Tags, Primary Tag for TeePublic, Amazon Merch Brand, Amazon Merch Bullet #1, Amazon Merch Bullet #2.
2. Fill one row per design. Column A is always the design's full file path on this computer, such as C:\Designs\batch-12\retired-nurse.png. Files on a network drive are refused, so copy them to the computer first.
3. Stay inside Amazon's limits. Title needs 3 to 60 characters and brand 3 to 50. The description is optional, but if you fill it in it needs at least 75 characters, up to 2,000. Bullets are optional, up to 256 each. Text over a maximum is cut without a warning, so keep within the limits yourself.
4. Load it. Click Upload spreadsheet, then Choose spreadsheet. The app shows the sheet as a table with "Does this look right?" underneath. Click Continue.
5. Match the columns if yours differ. The template's order matches the app's default columns: B Title, C Description, D Tags, E TeePublic primary tag, F Brand, G and H the bullets. If your sheet uses other columns, set them under "Spreadsheet columns" on each marketplace page.
6. Tick and start. The upload screen opens. Tick the listings and press Start upload.

Rules the app enforces: only the first sheet is read, the header row is optional, the file must be an Excel file under 50 MB, and column A must point to an image file that exists. If a row breaks Amazon's minimums, a "Please fix these spreadsheet rows" dialog lists the marketplace, the row and what to fix before anything uploads.

This route has no trademark check. If you want one, run your phrases through the free trademark checker or load the designs into Easy Mode instead. Full details are in the spreadsheet upload docs.

What Happens When You Press Start Upload

In order:

1. Licence check. The first upload from a computer asks which subscription to activate it on. Each subscription covers 2 computers (licence and computers).
2. Row and settings checks. Problems show in a dialog before anything is sent.
3. Launch. Each marketplace you ticked listings for starts 2 seconds after the one before, then they all run at the same time. A marketplace with nothing ticked doesn't open at all.
4. Amazon, one listing at a time. Amazon listings go one after another in a single tab, with a random pause of 5 to 10 seconds between them. A listing that takes over 20 minutes is skipped with a message, and the run carries on.
5. Failures stay contained. If one marketplace stops, the others keep going.

The app fills Amazon's own create page in its own browser window. It doesn't use a hidden Amazon API, and no tool can promise Amazon won't act on your listings, so your content still has to follow Amazon's rules.

Following the Run and Retrying Failures

The Upload Status page shows one box per run, with a count, a progress bar and an icon per marketplace. Click Manage Uploads to see each listing: "Publishing" while it works, a done label such as "Published" when it finishes, and "Failed" with the reason when something goes wrong. A failure also shows a message such as "Listing 14 was not uploaded", followed by the reason.

To retry, open Manage Uploads, press Only unfinished, then Start upload. Don't use Select all on a rerun: it ticks finished listings too, and Amazon will get them a second time.

Upload Status isn't kept after you close the app. What is kept: listings published in the last 180 days start unticked when you load the same designs and text again, and Reopen last upload in the sidebar brings back your last Easy Mode batch. Drafts aren't remembered as finished, so they show up as unfinished again. See the Upload Status docs.

The Contrarian Part: A Bigger Batch Isn't Always Faster

A bulk upload tool doesn't raise your Amazon limits. Merch Titans doesn't read or enforce Amazon's daily upload limit or your tier. If your batch is bigger than what Amazon will take today, tick only that many Amazon listings, run them, and send the rest another day with Only unfinished.

And a 100-design batch with weak listings is just 100 weak listings, live sooner. The time you save on form-filling is best spent on the two things the app can't do for you: keyword research before you design, and reading every listing before you press Start upload.

Common Mistakes

• Network drive paths in column A. Copy the files to the computer.
• A brand under 3 characters, or a description between 1 and 74 characters. Both are stopped before upload.
• Assuming the trademark check ran. It only runs when you click it in Easy Mode.
• Unticking the agreement box on Home. The upload buttons then do nothing, with no message.
• Using Select all on a rerun, which posts finished Amazon listings again.
• Ignoring Amazon's daily limit. The app won't stop at it for you.
