Verified steps Base URL depends on your dc: https://{dc}.api.mailchimp.com/3.0 (dc is in the API key suffix) PUT /lists/{list_id}/members/{md5_of_lowercase_email} with status 'subscribed' (idempotent upsert) Add tags via POST /lists/{list_id}/members/{hash}/tags Tag-triggered automations fire on tag add Known gotchas Member endpoint id is the MD5 hash of the LOWERCASED email — uppercase emails create duplicate-looking 404s status 'pending' sends double-opt-in confirmation; 'subscribed' skips it (compliance implications) Deleted (not archived) members can NEVER be re-added via API — archive instead
