Why connect Klaviyo to Codex?

Codex runs in your terminal, its IDE extension and scripts, so what it finds once can be rerun with codex exec instead of redone by hand. Connected through Lemonado, it reads your Klaviyo campaigns, flows, segments and attributed revenue, so it can check what Klaviyo claims against Shopify revenue with today's numbers.

  • All your Klaviyo data

    Email and SMS campaigns, ready to ask about.

  • Always today's numbers

    Opens, clicks, unsubscribes and spam complaints, synced from Klaviyo automatically, so answers use today's numbers.

  • Connect all your tools

    Questions like "Does Klaviyo over-claim?" use Klaviyo and Shopify, Meta Ads at once.

What can Codex do with Klaviyo?

Codex reads your Klaviyo data from your terminal and turns one-off questions into commands you can rerun with codex exec.

Codex logoCodex

Pull last week's Klaviyo numbers, save them to data/klaviyo-weekly.csv and give me the codex exec command to refresh it.

Saved data/klaviyo-weekly.csv. Run the same prompt with codex exec in a scheduled job and the file refreshes with each week's numbers.
