I have created an integration between Facebook and Klaviyo, where people who sign up via our Lead Ads campaign are automatically added to a list in Klaviyo and receive an email. The problem is that not everyone who signs up gets into Klaviyo. For example, 27 people signed up today, but only 12 of them are on the Klaviyo list. Why does it happen?
Integration between Facebook and klaviyo does not work perfectly

Hello
The issue of missing leads in Klaviyo from Facebook Lead Ads can be due to incorrect integration settings, unmapped forms, duplicate emails, invalid submissions, or syncing delays. Verify the integration is active, reauthorize Facebook, and ensure the correct Lead Ad form is linked. Check for duplicates or leads requiring double opt-in confirmation. If field mapping or API errors persist, manually upload leads as a temporary solution. For detailed troubleshooting or implementation, feel free to reach out.
