Know who logs in to your Webflow site and get the list of user emails imported to Webflow CMS.
When you integrated Cotter to your site and a user logs in using Cotter's Login Form, Cotter will immediately create a new user for you. This user is stored in Cotter's database and can be accessed through our Zapier integration. Using Zapier, you can send user data to Webflow CMS. The user data that are available are defined in the documentation for User object.
