Introduce a new feature in the client dashboard (my.socialasking.com) that allows clients to view, manage, and export a list of users who have participated in at least one of their engagements. The feature will include the ability to export these user lists for integration with external mailing systems like Mailchimp or other CRMs. The user list will only display users who have opted in to share their email addresses, respecting user privacy and consent. This enhancement aims to facilitate better user management and engagement strategies for clients, enabling them to easily reach out to their engaged audience through their preferred communication channels.
