Configuration
10 fields, 2 required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.

list_id The audience (list) id, as shown in Mailchimp under Audience settings and returned as 'id' by Mailchimp: List Audiences. | string | Yes | — | — | — |
email The member's email address. Mailchimp addresses a member by the MD5 of the lowercased address, which this node derives for you; a 32-character subscriber hash from an earlier step is accepted as-is. | string | Yes | — | — | — |
new_email A new email address for this member. Leave empty to keep the current one; changing it also changes the member's subscriber hash. | string | No | — | — | — |
