# SendGrid review

> Twilio SendGrid high-volume sending APIs and SMTP relay for established stacks.

- **Canonical:** https://growthmarketing.engineering/tools/sendgrid
- **Rating:** 4.1/5

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.

## Pros

- 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

## Cons

- 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

## What SendGrid is

[SendGrid](https://sendgrid.com), 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](https://brew.new/browse/integrations/sendgrid) when you generate creative elsewhere and deliver through Twilio infrastructure.
