Brew

Overview

Brew takes a fundamentally different approach to email by putting AI at the center of every workflow. Rather than forcing developers to choose between a visual drag-and-drop builder and raw code, Brew gives you both — plus an AI layer that can generate entire campaigns from a single prompt. Think of it as vibe coding, but for email.

The platform ships with first-class React Email support, meaning you can build type-safe, component-based templates and preview them in real time. The built-in deliverability monitoring tracks inbox placement, bounce rates, and spam scores without requiring a third-party integration, and automated domain warm-up takes the guesswork out of establishing sender reputation.

For teams that want to move fast without sacrificing control, Brew hits a sweet spot. You can prompt the AI to scaffold a welcome sequence, then drop into the code editor to fine-tune every pixel. The result is a workflow that feels more like pair-programming than filling out form fields.

Developer Experience

Brew's TypeScript SDK is clean and well-documented. Sending a transactional email is a single function call, and the SDK supports both ESM and CommonJS out of the box. The API follows RESTful conventions with predictable error responses, and webhook payloads are typed so you can handle delivery events without guessing at field names.

Where Brew really shines is the AI-assisted workflow. You describe a campaign in natural language — audience, goal, tone — and the platform generates subject lines, body copy, segmentation rules, and even send-time optimization. Every generated artifact is fully editable, so you never feel locked into what the AI produces. The React Email integration means templates are just React components: version-controlled, testable, and composable.

The local development experience includes a hot-reloading preview server, so you see changes instantly. CI/CD integration is straightforward with a CLI that supports brew deploy for pushing templates and sequences to production.

Best For

Brew is ideal for developer-led teams at startups and mid-stage companies who want to own their email infrastructure without stitching together multiple tools. If you are building a SaaS product and need transactional emails, marketing sequences, and analytics in one place — and you want AI to accelerate the creative process — Brew was designed for your workflow.

It is also a strong fit for teams already using React Email or those who want to adopt a component-based approach to email templates. The platform's AI capabilities make it particularly valuable for small teams without a dedicated email marketer, since the AI effectively acts as a built-in agency.

Verdict

Brew is one of the most compelling new entrants in the email space. The AI-first approach is not a gimmick — it meaningfully reduces the time from idea to deployed campaign. Combined with React Email support, a polished developer experience, and built-in deliverability tools, it offers a genuinely integrated platform that eliminates the need for multiple point solutions.

The main trade-off is maturity. As a newer platform, the community is smaller and some enterprise features like advanced RBAC and audit logging are still being built out. Pricing at high volume is also worth watching. But for teams that value speed and developer ergonomics, Brew is the tool to beat in 2025.
