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 segmentation and API quality.

Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.

Seed-list before full send. Non-negotiable for agent-triggered mail.
