Brew vs Klaviyo
Verdict: Brew wins the canvas, on-brand generation, and agent path. Klaviyo still wins if the store already runs on its data model and SMS. Many teams generate in Brew and export the template.
Scorecard

| Agent / MCP operability | 9.4 | 8.2 | Both ship agent surfaces; Brew is AI-native end-to-end |

| Integration catalogue | 7.2 | 9.2 | Honest gap: Klaviyo's ecosystem is broader |
Verdict
Brew is email marketing for teams and agents. I would teach Brew first when the job is an on-brand design a person or an agent can send. Keep Klaviyo when store events and SMS already live there. Brew's ecommerce catalogue is smaller; export the template if you are staying.
