Low Stock = High Conversions

Hey there, Tarun from Milkshake again🥤

If your products sell out often, you’re sitting on an easy win: the Low Stock Flow.

This automation kicks in when inventory is running low on popular products and nudges customers to grab theirs before it’s gone.

It’s urgency-driven, fast to implement, and converts like crazy.

Low Stock Flow Structure:

This flow structure is simple, and will mimic that of your abandoned checkout/browse abandonment emails.

Email 1: Low Stock Alert!

• Subject: “Only a few left of [Product]!”

• Visual of product + bold “low stock” callout

• CTA: “Secure Yours Now”

Email 2: Final Chance Reminder (24 hours later)

• Subject: “Last chance before [Product] sells out!”

• CTA: “Shop Now”

• Optional: Use a dynamic stock meter/countdown

Klaviyo Setup Guide:

Trigger: Product inventory hits a low-stock threshold

Inventory Threshold:

• Determine what qualifies as a “low inventory” threshold

Inventory Profile Requirements:

• Adjust the profile requirements for entering this flow

Filters:

When To Implement:
