The three blocks
-
Checkout Links — Abandoned Cart CTA — a button that sends a shopper straight back to their cart to finish checking out.
-
Checkout Links — Reorder CTA — a button that pre-fills checkout with a returning customer’s details for one-click replenishment.
-
Checkout Links — Reorder Banner — a ready-styled banner with a “Reorder now” link, for the top of your reorder emails.
Using a block in your emails
In Klaviyo, open your email or template editor and look in your saved content library. Search Checkout to find the three blocks, then drag the one you want into your email. The link inside is already set up.
The blocks point at two fixed slugs on your store: the Abandoned Cart CTA at cl/abandon, and both reorder blocks at cl/reorder. Create a link at each slug you use — see Abandoned cart recovery with Klaviyo and Reorder links with Klaviyo.
How personalization works
Each block’s link uses your customer’s unique Checkout Links shortcode, so every recipient gets a checkout pre-filled for them:
https://yourstore.com/cl/abandon?c=#{{ person.checkout_links_shortcode }}The shortcode is added to each customer’s Klaviyo profile automatically. New customers sync within a minute or two; to sync everyone who already has a Klaviyo profile, use Sync shortcodes on the Klaviyo settings page.
Styling
The button blocks come with a plain default style. You can restyle any block in Klaviyo’s editor like any other content block — your changes stay put.
Reinstalling the blocks
If you delete or break a block, go to Settings > Klaviyo in Checkout Links and click Reinstall blocks. This deletes the three Checkout Links blocks in Klaviyo and creates fresh ones — any changes you made to them are lost, and you may need to add the new blocks to your emails again.
