The Ultimate Member Mailchimp add-on syncs profile fields and registration opt-ins with Mailchimp audiences. Each member's list memberships and opt-in state are stored as usermeta keys (commonly _um_mailchimp_lists or per-list flags) tied to the Mailchimp list_id, with the registration timestamp from wp_users.user_registered acting as the opt-in date. The default surface is a per-profile Mailchimp panel, which is right for one-member-at-a-time review and unhelpful for understanding audience health across the community.

SleekView Charts reads the Ultimate Member Mailchimp usermeta joined with wp_users and renders the result as chart cards. A Number card counts total opt-in subscribers across the lists. A Pie shows the per-list subscriber mix so marketers see how attention is distributed. A Bar ranks lists by subscriber count for the audience audit. An Area trends opt-ins per day so newsletter promotions and campaign-triggered sign-ups become visible.

Filters on the audit table (list_id, opt-in status, UM role) carry across to the chart view, so a single-list or last-30-days dashboard narrows every card simultaneously. Cards read the Mailchimp opt-in state the add-on already writes to usermeta, so no duplicate audience store is introduced.

Ultimate Member Mailchimp captures the data marketers need: who opted in, to which list, with what status, when. The default surface places that data inside per-profile Mailchimp panels, which is right for one-member-at-a-time review and unhelpful for almost everything operators do with audience data at the cohort level. A total-subscribers KPI anchors monthly newsletter reports, an opt-in-status Pie confirms the consent funnel is healthy, a per-list Bar produces real prioritisation decisions and an Area on user_registered tells the team whether registration-form changes or lead-magnet campaigns actually grew the lists.

Same usermeta rows, same registration timestamps, completely different decision posture. The charts render the audience the add-on already maintains as a dashboard, which is the difference between knowing the site has subscribers and knowing how the audience is shaped this quarter.
