FAQ

Overview · Installation · Configuration · Usage · Developer notes

Do I need a paid Klaviyo or Brevo plan? You need your own account. Free plans work within their limits; the add-on adds no fees of its own.

Is a tracking script added to my storefront? No. Everything is sent from the server. Viewed Product is therefore only sent for signed-in customers.

Does the checkout wait for Klaviyo or Brevo? On PHP-FPM hosting the jobs are sent after the page was delivered. On other hosting a few jobs are sent at the end of the request; turn off “Send right after each page” and use the cron job if you prefer.

Which emails are never sent? Placeholder emails that CS-Cart creates when the checkout does not ask for an email ([email protected]).

What happens to customers who unsubscribe in Klaviyo or Brevo? They stay unsubscribed there; the add-on never resubscribes anyone without a new opt-in in your store.

Can I keep using the Newsletters add-on? Yes. With the bridge on, its subscriptions count as consent and are synced; our own checkbox stays hidden where a Newsletters list is shown.

Was it tested with live accounts? It was tested against a local server that answers like the Klaviyo and Brevo APIs. Please test with your account (Test connection, one test order) before you start flows.

Still stuck?

Work through the troubleshooting guide, then contact support with your CS-Cart version, edition, PHP version and the add-on version (1.0.0).
