Multiple sources, including Mailchimp's own documentation and various email marketing experts, confirm that Mailchimp records subscriber IP addresses upon signup, even with single opt-in forms. While Mailchimp tracks this data, it's not always readily visible within the user interface. Accessing the IP address usually requires exporting the subscriber list as a CSV file, where it can be found in the `CONFIRM_IP` column. Utilizing IP addresses involves careful consideration of GDPR and other relevant privacy regulations, emphasizing the need for explicit consent. The legality of recording and using IP addresses depends on local laws and Mailchimp's adherence to its data security policies. You can use the IP to find the geolocation, device type and understand the customer better.
