When Intercom and Mailchimp operate in isolation, customer interactions captured in Intercom are not reflected in Mailchimp's audience segmentation. For instance, if a support agent resolves a ticket in Intercom but fails to update the customer's status in Mailchimp, that customer may continue receiving irrelevant marketing emails. This leads to wasted marketing efforts and potential customer frustration. The marketing team spends excessive time manually cross-referencing customer data, which could be automated.

Top Ways to Automate Intercom & Mailchimp

Automated Lead Nurturing: Seamlessly transfer leads captured in Intercom to Mailchimp, triggering personalized email campaigns that nurture prospects based on their interactions and behaviors.
Targeted Customer Segmentation: Utilize customer data from Intercom to create highly targeted segments in Mailchimp, ensuring that your marketing messages resonate with the right audience at the right time.
Real-Time Customer Feedback Loop: Automatically sync customer feedback collected via Intercom into Mailchimp, allowing you to adjust your marketing strategies in real-time based on customer insights and preferences.

How to Build the Intercom → Mailchimp Sync

In Intercom, configure a Standard Webhook to trigger on 'Conversation Resolved' events. Set the webhook to point to your server endpoint, e.g., https://yourserver.com/intercom-webhook.
On your server, listen for incoming POST requests from Intercom. Extract the relevant payload data, specifically the user's email and any tags or properties that indicate their status.
Once you have the user data, format a POST request to the Mailchimp API endpoint https://.api.mailchimp.com/3.0/lists//members/. Include the user's email and any relevant merge fields in the request body.
Ensure that you handle the Mailchimp response appropriately, checking for success or failure to confirm that the update was processed.

Developer Warnings & API Gotchas

Ensure that the email format in the Intercom payload matches the expected format in Mailchimp; discrepancies can cause the API call to fail.
Be cautious with the data types for merge fields; Mailchimp expects specific formats, such as dates in 'YYYY-MM-DD' format, which may differ from how Intercom sends them.
When updating a user in Mailchimp, if the user is already subscribed, make sure to handle the response correctly to avoid duplicate entries or overwriting existing data unintentionally.
