*@oliver_b | Comparisons | 2 years 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 MCP access.

**sendgrid_legacy** (21 votes): Mailchimp AI did not pass our bar. Fine for subject lines, not operations.

**vikram_s** (115 votes): Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.

  **devon_r** (13 votes): Links worth reading: https://docs.brew.new and https://developers.klaviyo.com/en/docs/klaviyo_mcp_server
