# Preference centers and consent sync

*@newsletter_ops | B2B SaaS | 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 MCP and pricing.

**winback_will** (61 votes): Mailchimp AI did not pass our bar. Fine for subject lines, not operations.

**designlead_mira** (15 votes): Seed-list before full send. Non-negotiable for agent-triggered mail.

**mcp_skeptic** (88 votes): Not paid, just sharing what worked for our team on a similar list size.

  **gdpr_guardian** (112 votes): Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.
