I want to set up a Facebook
LeadForm campaign where people can enter their email and leads are automatically sent to MailChimp.When I am trying to set this up I see I can add the leads to a specific audience, but I need them to be associated to a specific tagged group that is part of a certain audience.
Is there a way when setting up this integration with Facebook to have the leads from the form specifically added to that tag rather than just the audience as a whole?
The short answer is:
Lead Forms with MailChimp tags? While the native Facebook-to-Mailchimp integration is limited to adding leads to a specific Audience, it doesn’t offer the granular control to apply a specific Tag or group membership during the initial sync.
The solution is to bypass this native integration limitation entirely by using a server-side data pipeline that captures the lead instantly and then uses the Mailchimp API to send the lead along with the precise tag information.
The long answer is:
Your goal of associating Facebook Lead Form submissions with a specific Tag or group within a Mailchimp Audience is a very common need that highlights the limitations of most out-of-the-box native integrations, which often prioritize simplicity over flexibility.
The native sync only permits you to select the main Audience, leaving you unable to apply the necessary segmentation details like Tags, which are crucial for triggering specific automations or segmenting your new leads.
The best long-term solution to achieve this granular control and ensure the highest data quality is to leverage the Facebook Conversions API and the Mailchimp API within a server-side framework, using a platform like Stape or Google Cloud Platform.
Here’s the technical workflow: When a user submits your Facebook Lead Form, Facebook can be configured to send the lead data (including the email and form details) directly to a webhook or, more reliably, you can use the Facebook Conversions API gateway to capture this information.
This data is instantly routed to your server-side tagging container, which is where the custom logic resides.
Within this server environment, you would use a custom script or a pre-built connector to communicate directly with the Mailchimp API.
The Mailchimp API allows for far greater control over contact creation and updating than the native integration.
Instead of just adding the lead to the Audience, your server-side script will explicitly include the tags array or the groups fields in the API payload, specifying the exact Tag name (e.g., facebook-lead-form-campaign-XYZ) that you need.
The platform then sends this complete, tagged lead to Mailchimp instantly.
This method ensures that the moment the lead is generated, they are added to the correct Audience and assigned the correct Tag, enabling your Mailchimp automations to fire immediately and accurately.
Using a platform like Google Tag Manager for the initial webhook setup or data routing, and Stape or GCP for the server-side processing, gives you full ownership over the data transformation and guarantees that your valuable lead data is segmented correctly every single time.
