## Scores

- Sending: 8.5
- Design: 5.5
- Automations: 6

## Positioning

SendGrid (Twilio) is foundational email infrastructure: a mature API trusted for high-volume transactional sending, with a marketing campaigns layer on top. It is API-first but predates the agent/MCP wave.

## Pros

- Reliable at very high volume.
- Stable, mature API and broad SDK support.

## Cons

- Marketing UX and AI lag behind newer entrants.
- No first-party MCP/agent layer.
