# SparkPost

> High-volume sender with deep analytics, now folded into Bird's platform.

SparkPost came out of Message Systems' on-premise MTA business and carried genuine deliverability engineering into the cloud: automatic IP warmup, detailed engagement analytics and very high throughput. Since the MessageBird acquisition it has been progressively absorbed into Bird, self-serve access has narrowed, and pricing above small volume goes through sales. Existing users are well served; new ones should check what they can still sign up for.

| Positioning | "Predictable email delivery at scale." The engineering is real; the product is increasingly a feature of Bird rather than a thing you buy. | Inferred | - | - | - |

**Verdict.** Genuinely good deliverability technology attached to an increasingly uncertain commercial story. Existing high-volume customers have little reason to move; new teams should not start here without confirming what self-serve still exists.
