What it does
When a customer's Stoq-subscribed variant comes back in stock, they get an email with a Checkout Link that drops the exact variant straight into checkout.
Why this play works
Stoq captures the back-in-stock subscribers — a Checkout Link makes the alert actually convert. Instead of dropping the customer back on the product page to re-add the variant, the link lands them straight at checkout with the right variant pre-loaded. Optionally attach a discount, free gift, or tiered promotion to nudge faster action.
What you'll need
Stoq installed with Shopify Flow connector enabled
A Checkout Link set as Dynamic so the variant pre-fills from the trigger
Klaviyo connected in Checkout Links
How it works
Trigger: Stoq — variant back in stock
Action: Use dynamic link (Checkout Links)
Action: Send Checkout Link
Tips
Back-in-stock subscribers self-selected — treat their inbox carefully. A direct-to-checkout link converts better than a pre-checkout page for this audience because they're already decided.
