Description
The MailChimp Lock addon blocks access to Download Monitor files until the visitor provides a valid email address, sending the contact directly to a MailChimp list through native integration with the official API. This capture mechanism turns every download made available by the base plugin into an entry point for the subscriber base, connecting free content strategies to email marketing automation without requiring external forms or additional scripts in the theme.
