5. Inventory, Quantity, Locations, SKU & Barcode

There are several key options for you to choose from and how your inventory will be processed.

SKU = Stock Keeping Unit
Barcode (ISBN, UPC, etc)
Track Quantity
Quantity - Available & Incoming
Locations

SKU = Stock Keeping Unit

This is your product tracking number for your inventory.

If you are using a manufacturer or vendor, it is probably easier using their product identification number as your SKU number. Especially when you are dropshipping your products.

It is a good practice to create your own internal SKU numbers and add your manufacturer or vendor Barcode or Identification number.

It is totally up to you

Barcode (ISBN, UPC, etc)

A barcode is an identification number for your manufacturer or vendor.

This is also the place to add your product identifier number for Amazon.

If you are selling your products on Amazon you will need a product identifier number.

AMAZON says:

“ For most categories, you are required to use a product identifier to create new product pages and listings. The specific GTIN (Global Trade Item Number) required for product page creation and matching varies by category. The following are the most commonly used GTINs in the Amazon catalog:

Universal Product Code (UPC)

International Standard Book Number (ISBN)

European Article Number (EAN)

Japanese Article Number (JAN)

The requirements of each category, including exceptions and exemptions where available, are summarized in the table on the Overview of category UPC requirements page.”

Once you create an Amazon Seller account, you will get all the information you need to create your product identifier number.

In my upcoming book - “How to Optimize Your Shopify Store” - I do an in-depth article about the Amazon sales channel.

Track Quantity

In this section, you have a choice to allocate who will track your inventory or if you even want to track inventory.

Once you check the ‘Track Quantity’ box, and you can also decide whether you want to ‘continue selling when out of stock’

If you create your one of a kind products, you probably don’t need to track your inventory. Unless you want to make sure to know which products are sold and show them sold online. The example below is one of a kind sculpture, and no incoming and no continue selling when out of stock.

If you do want to track your inventory, check the box in this section!

Shopify by default manages the tracking, which means your Shopify store and not Shopify the company, tracks your inventory.

You can then choose to ‘Continue selling when out of stock’ - so basically your customers can still buy even if your inventory is at ‘0’.

There are extra advantages with a Paid Shopify theme:

Instead of ‘Sold Out’ on your product page, it gives your buyer an opportunity to enable a ‘back in stock’ request.

This is probably a good suggestion if you are hand-making your product. and the products would not be available immediately.

What does it look like on the product page?

In order for the form to appear, your product must meet all of the following requirements under the "Inventory" section of the product management page:

The product must be active and available in the online store sales channel
Have the "Shopify tracks this product's inventory" inventory policy selected
Have a stock level of 0 or lower
Have the "Allow customers to purchase this product when it's out of stock" option DISABLED

Quantity

Now you can add your available quantities of products.

If, however, you have different locations, you will be able to choose from which location the product will ship and what inventory is available from that location.

Here you can add a different location and change the quantities from the location.

If you have products that are incoming from vendors, this is not where you will add any incoming products.

This will open another section in Shopify, ‘Transfers’.

You can add additional information in this section for your incoming products::

Quantity
Origin
Expected arrival time

Why Your Shopify Emails Might Be Going to Spam (And How to Fix It)

By Veronica Jeans, Bestselling Author July 11, 2025

If you’ve been wondering why your carefully crafted Shopify emails aren’t reaching your customers, you’re not alone. Many Shopify store owners run into this issue — they set up everything, send out campaigns, and then see disappointing open rates or no response.

So, why are your Shopify emails ending up in spam folders? And more importantly, how can you fix it?

Why Your Shopify Emails Might Be Landing in Spam

1. Using a Free Email Domain (like Gmail, Yahoo, etc.)
Sending store emails from an address like yourstore@gmail.com raises immediate red flags for spam filters. It looks unprofessional and is commonly linked to phishing or spam.

How to fix it: Use a branded domain email like hello@yourstore.com. Shopify offers alias emails when you register your domain, or you can set up hosted email through services like Google Workspace or Zoho.

2. Missing Email Authentication (SPF, DKIM, DMARC)
Email providers such as Gmail and Outlook check for authentication records to verify that your emails are legitimate. Without these, your messages are more likely to be marked as spam.

How to fix it: Set up SPF, DKIM, and DMARC records in your domain’s DNS settings. Shopify help docs or your domain host can walk you through it, or you can ask your tech support team to help.

3. Low Engagement Rates
When recipients don’t open, click, or interact with your emails, inbox providers start pushing future emails into spam folders.

How to fix it: Regularly clean your email list by removing inactive subscribers. Focus on sending more relevant, engaging content, and use segmentation so you’re not sending the same message to everyone.

4. Spammy Content or Design
Using all caps, excessive exclamation marks, or spam-triggering words like “BUY NOW” or “FREE $$$” can set off spam filters.

How to fix it: Write conversational, natural-sounding copy. Avoid overhyped or misleading language. You can also test your emails through tools like Mail Tester before sending.

5. No Unsubscribe Option
Not including an unsubscribe link is not only bad practice but also violates regulations like CAN-SPAM and GDPR.

How to fix it: Make sure every email includes a clear unsubscribe link. Shopify Email, Klaviyo, Omnisend, and similar platforms typically add this automatically.

6. Too Many Images, Not Enough Text
Emails that are made up of only images or only text can trigger spam filters. A healthy balance matters.

How to fix it: Combine text with visuals and always add alt text to images for better accessibility and email trust.

Tips to Improve Deliverability

If you are using a new email domain, warm it up by sending to smaller segments first, then gradually increasing your send volume.
Ask subscribers to add your email to their contacts or address book to help avoid future spam filtering.
Monitor your sender reputation with tools like Postmark, GlockApps, or Google Postmaster Tools to identify issues early.

Bottom Line...

Email marketing is one of the most powerful tools you have to drive sales, but only if your emails actually reach your customers. By improving your sending practices, maintaining a healthy list, and following best practices, you can significantly increase your deliverability, boost open rates, and make sure your efforts pay off.
