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.

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.
