True or False: When you edit an embedded data value for a member of a mailing list, that member will be updated in all lists they are a part of.

When you edit an embedded data value for a member of a mailing list, that change applies universally to the member across all mailing lists they belong to. The reason this is true is that embedded data values are tied to individual contacts in your account rather than to specific lists. Thus, any updates made to a member's data will reflect in all instances where that member is included, ensuring that their information remains consistent and up-to-date regardless of the mailing list context.

This system is designed for efficiency and accuracy, as it eliminates the need for duplicate updates across multiple lists, reducing the risk of having conflicting or outdated information about the same member.
