Loading Klaviyo in shopify store cost almost 1MB for downloading all js files.


Are you serious?

How we can optimize those js scripts?

Hi @David B.

Thanks so much for sharing this in the Community forum! Our team is aware that Klaviyo .js can be flagged in performance analyses. Our team is currently investigating ways to improve our JS performance and looking into building ways to benchmark our JS more reliably.

We don't have more details on the timelines for this, but we will post in this thread and update the Community when there is more to share. 

Thanks again,

Any updates on this?


Community Managers specially David.To why you didn’t like my post as well?


How stupid this looks in this community that Klavyio workers are liking each other posts.
