Does Mailchimp train on your data?

We can't tell. Mailchimp's published policy doesn't clearly say. As of 10 November 2026. Source: mailchimp.com.

PolicyPeek gives Mailchimp the badge "Policy unclear". Its published policy doesn't clearly say whether your data is used for training, or whether you can opt out. What we recorded from the policy: "We may use your Inputs and Outputs, including Customer Data, for machine learning purposes in order to develop and improve the AI Model, the Services, and similar products and features, and you instruct us to process Customer Data for such purposes. You may select preferences about your data by visiting your account settings." The only documented setting (Data analytics) never mentions AI, models or training. The published pages do not clearly say whether this use is on by default, or whether that setting would stop it.

Does Mailchimp train on my data?

Two different things often get mixed up. Used to train models means your content helps build or improve the AI itself, so it can shape what the model produces later. Used to provide the feature means your content is processed to give you the answer, summary or suggestion you asked for, which any AI feature has to do. PolicyPeek's badge is about the first one only.

What Mailchimp's policy says (mailchimp.com):

We may use your Inputs and Outputs, including Customer Data, for machine learning purposes in order to develop and improve the AI Model, the Services, and similar products and features, and you instruct us to process Customer Data for such purposes. You may select preferences about your data by visiting your account settings.

Is Mailchimp safe for UK GDPR?

PolicyPeek hasn't recorded whether Mailchimp's published policy mentions GDPR. PolicyPeek doesn't assess whether a tool meets GDPR; the badge only reports what the policy says about training.

In the UK: if personal data is involved, the UK GDPR applies to how it's used, including for AI. This page only reports what the vendor's published policy says about training — it is not a finding that Mailchimp meets UK GDPR, and it is not legal advice. The Information Commissioner's Office publishes guidance on AI and data protection.
