Help with Facebook Leads and Email Lists. (Conditional Logic)

I’ve setup a simple scenario where when a new lead is detected it takes that email and subscribers them to my email list.

However, this scenario breaks whenever an existing subscriber opts in via the leads form and I have to manually reset it. Saying the subscriber is already on the list and I need to use the PUT function instead. I have no idea what to do with that and would love some assistance.

Hey @Michael_Lee,

You may want to add a step after the Facebook Lead Ads trigger to see if a subscriber already exists in Mailchimp. You could use the ‘Search Subscribers’ action, and set up a filter where it only continues if the result is 0.

You could also use the ‘Get a Subscriber’ action, and check what happens if it doesn’t find any. It will probably throw an error, for which you can use an error handler (right click on the action, ‘Add error handler’) where you can set up the Mailchimp action.

Hope this was helpful!
