The Mailchimp integration automatically adds customers to your Mailchimp audience and syncs their marketing status, contact fields, and custom data in real time.

​
How it works

The Mailchimp integration keeps your audience updated as users move through your funnels. When a user interacts with a funnel:
  1. Contact creation: FunnelFox creates a contact in your selected Mailchimp audience when a user provides their email using the Email Input element.
  2. Marketing subscription: FunnelFox updates the contact’s marketing status in Mailchimp.
  • Subscribed: If the user checks the consent checkbox in your funnel. These users are opted in to receive your marketing content.
  • Non-subscribed: If the user leaves the consent checkbox empty. Non-subscribed contacts won’t receive marketing emails, but they can still receive transactional emails.
  1. Contact details: FunnelFox sends funnel context and manages tags in Mailchimp so you can segment users and trigger automations based on where they are in your flow. Here’s what FunnelFox sends to Mailchimp:
  • Email
  • Phone (if provided in the funnel)
  • Funnel ID
  • Profile ID
  • Session ID
  • Experiment ID (if applicable)
  • Project ID
You can connect multiple projects to the same Mailchimp audience and segment users by project ID.
We recommend creating a new audience in Mailchimp for this integration. If you connect to an existing audience, FunnelFox-managed tags may overwrite existing tags when users interact with your funnel.

Troubleshooting

If contacts aren’t appearing in your Mailchimp audience, check that you’re using valid email domains for testing.Mailchimp rejects emails with fake or invalid domains like [email protected] or [email protected]. For testing, use emails with real domains like @gmail.com or similar.
