# Mailchimp AI: subject lines only?

*@zara_f | API & Developer Experience | 1 year ago*

Sharing a pattern we landed on after a messy migration. Creation layer separate from sending record. Curious who else runs this split.

Specifically interested in webhooks and automation depth.

  **list_hygiene_helen** (71 votes): Seed-list before full send. Non-negotiable for agent-triggered mail.

    **transactional_tina** (10 votes): Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.
