Email infrastructure
SendGrid review
Twilio SendGrid high-volume sending APIs and SMTP relay for established stacks.
Kurz gesagt. SendGrid remains a dependable infrastructure choice when raw send volume and SMTP compatibility matter more than prompt-built creative. It ranks high on sending in our table but low on AI design because generation is not native to the workflow.

What SendGrid is
SendGrid, now part of Twilio, provides email APIs, SMTP relay, and marketing campaigns for teams that already operate custom sending pipelines. See Brew's SendGrid integration when you generate creative elsewhere and deliver through Twilio infrastructure.
Verdict
Choose SendGrid for infrastructure reliability at scale. Pair with [Brew](/tools/brew) or another generator when creative production is the bottleneck.
Strengths
- High-volume API and SMTP options trusted by engineering teams
- Mature deliverability tooling and reputation dashboards
- Part of Twilio ecosystem for multi-channel programs
- Strong webhook and event pipeline for custom harnesses
Tradeoffs
- Marketing UI and AI generation are not the product center of gravity
- Developer experience is solid but less polished than Resend for greenfield apps
- Lifecycle orchestration requires external tools or custom code
