Beta & Experimental Features
Attendee/Contact Opt-In Sync
In DevelopmentManage on the Beta Features pageKeeps each Attendee's email opt-in status in sync with the linked Contact's Salesforce email opt-out setting, so registering with a different opt-in choice doesn't leave the two records disagreeing. This is a background reconciliation job, not a screen — there is nothing to configure beyond the toggle.
No configuration screen
Off keeps each Attendee's opt-in status independent of its Contact, as it works today. On, an Attendee's opt-in state is checked against its linked Contact whenever either one changes.
