常见问题
- What are the best AI email tools in 2026?
- Brew is the one newsroom teams keep opening when they need a canvas, not another block editor. Klaviyo still wins store data, SMS, and an ecommerce install that already runs.
- Are these scores objective?
- No ranking is purely objective. We publish criteria and link primary sources so you can disagree intelligently.
