Hi @alejandro.gutierrez@bakertools,

Thanks for sharing this with our Klaviyo Community.

If you are using a Klaviyo form, individuals who fill the form will receive a double opt-in email and will need to confirm their subscription via email before being added to the list. In theory, these users could be subscribing and waiting before confirming their subscription which would account for the delay. Alternatively, you can set the list to single opt-in under the list settings, which will circumvent the confirmation step altogether and add these users directly to the list.

If you are using a 3rd party form, these forms can take longer to sync users to a Klaviyo list. I am attaching our article on how often integrations sync for you to verify if this is the reason behind the hour long wait before the user is added to the list. For example, Typeform forms will take an hour before the user syncs to Klaviyo. 

Thanks for being a member of our Community.

Hi Dov, 

Thank’u very much for your help! 

But I’m using the facebook forms, in a potential client campaign Facebook. Does this information also apply to this? 

Best Regards

Hello @alejandro.gutierrez@bakertools,

 The wonderful information shared by @dov.derin would still apply to Facebook forms and leads being synced to Klaviyo. As detailed in the how often integrations sync article he provided, Facebook syncs with Klaviyo every hour. I’ve also provided a chart of how often integrations syncs for your convenience below:

I hope this helps!
