How to set up Klaviyo's Low Inventory Flow
The wait is over! If you’ve been dreaming of automating scarcity marketing with email, Klaviyo’s Low Inventory Flow is finally here and it’s about to change the way you drive sales.
For years, scarcity tactics have been a go-to strategy for brands looking to boost urgency and conversions. Now, Klaviyo has made it easier than ever to trigger these messages when your product stock drops below a certain level. Less manual work, more “SOLD OUT” moments, yesss!
Why is the Low Inventory Flow so powerful?
Scarcity works. Plain and simple. For brands that sell popular, collectable, or slow-to-restock products, alerting customers when stock is low can:
Create urgency: Messages like “Only 2 left in stock!” prompt immediate action.
Build trust: Customers feel like they’re “in the know” and won’t miss out.
Drive quick sales: The fear of missing out (FOMO) is real, and the Low Inventory Flow taps right into it.
Here’s a real-life example:
One of my clients sells limited-edition items that fly off the shelves. Their customers love knowing when stock is running low, so campaigns with subject lines like “Get it before it’s gone!” or “Low inventory alert!” perform incredibly well.
When Klaviyo introduced the Low Inventory Flow, we implemented it immediately. The results? Sales started rolling in within the first week.
If your audience responds well to phrases like:
“Only X left in stock—act fast!”
“Low inventory alert—don’t miss out!”
… then this flow is a game-changer for your business.
How does the Klaviyo Low Inventory Flow work?
The Low Inventory Flow lives inside Klaviyo’s Flow Library and is super simple to set up:
Trigger: The flow activates when your Shopify product stock levels fall below a threshold you choose (e.g., fewer than 5 units remaining).
Dynamic Product Table: The email automatically pulls in product titles, images, and links in real time.
But here’s the thing: While the default setup is functional, it’s not particularly inspiring. That’s why I recommend giving the design a little extra love to match your brand and make it more engaging.
How to customise the Low Inventory Flow for maximum impact
Here are a few tweaks I made for my clients that you can try too:
On-brand design: Update the email layout to align with your brand colours, fonts, and tone. A polished design builds trust and makes your email stand out.
Dynamic product blocks: Keep the real-time product updates, but ensure titles, images, and CTAs (like “SHOP NOW”) look clean and clickable.
Clear urgency: Use compelling copy like:
“Almost gone—don’t miss out!”
“Low stock alert: only a few left in your size.”
These small tweaks turn a basic notification into a high-converting email that feels tailored and professional.
