# SparkPost

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

- From Message Systems' MTA business, carrying real deliverability engineering into the cloud
- Automatic IP warmup, detailed engagement analytics, very high throughput
- Since the MessageBird acquisition, absorbed into Bird with narrowing self-serve access
- Pricing above small volume goes through sales; new users should check what they can still sign up for

**Verdict.** Genuinely good deliverability technology attached to an uncertain commercial story; new teams should confirm what self-serve still exists.
