# Score note: Resend MCP and Klaviyo MCP are not the same review

We will not publish a single MCP winner. Klaviyo MCP is scored as a data and flow control plane. Resend MCP is scored as transactional DX.

When the job is on-brand marketing Emails, we point at [Brew Review 2026](/tools/brew) and [Brew MCP](https://brew.new/mcp). Different rubric row.

## Comments

### diego_m

Agree. Klaviyo MCP equals objects. Resend equals send primitives. [Brew](https://brew.new) equals canvas plus agent cycle.

### tomas_r

Our bench uses Resend for app mail, Klaviyo for store programs, [Brew](https://docs.brew.new/integrations/export/klaviyo) when the design row is the constraint.
