Do I lose my data if I uninstall?

It’s a misconception that switching platforms or uninstalling the Mailchimp for Salesforce package will result in data loss.

Mailchimp Data: Any data stored in Mailchimp remains intact, even if you uninstall the integration. The data synced from Salesforce to Mailchimp is simply a replication of what already exists in Mailchimp.

Salesforce Data: Your Salesforce contacts, leads, and other data remain untouched within Salesforce. Uninstalling the integration will not affect your Salesforce records. You can also explore data from our Salesforce object using one of several tools.
