Hi everyone,
I wanted to open a discussion around the use of Klaviyo for syncing audiences to advertising platforms (Meta, Google, etc.), as we’ve been running into recurring challenges.
On our side, segments are correctly updated in Klaviyo, but we often notice:
-
significant delays in audience updates on ad platforms,
-
noticeable gaps between Klaviyo segment sizes and the audiences actually available in Meta or Google,
-
and more generally, limitations when working with more granular or highly dynamic segments.
As we’ve looked into it, it doesn’t seem to be a bug per se, but rather a limitation of how these integrations work. Klaviyo feels very effective as a first-layer CRM audience, but more constrained when used as a primary “audience generator” for paid media at scale.
👉 I’d be really interested in hearing from others:
-
Are you experiencing similar limitations?
-
How are you currently using Klaviyo audiences for ads (retargeting, exclusions, lookalikes, etc.)?
-
Have you added other tools or workflows to manage ad audiences more reliably?
-
Or have you found best practices that make these syncs more stable?
Thanks in advance for sharing your experiences 🙏
