The same deliverability heritage, at whatever scale you need.

Most teams send through the Bird Email API directly. These products serve the teams that need something more: infrastructure they run themselves, or intelligence on how their mail is actually performing.

On-prem sending, deliverability intelligence, one heritage.

Enterprise email FAQ

What's the difference between Momentum MTA and PowerMTA?

Both are on-prem MTAs you run yourself instead of sending through Bird's managed API. Momentum MTA is built around customizable workflows and routing for high-volume sending; PowerMTA is built to run on your own servers or any public cloud, such as AWS or Azure.

Do I need to run my own MTA to use Inbox Tracker or Competitive Tracker?

No. Inbox Tracker and Competitive Tracker are deliverability-intelligence products: Inbox Tracker measures inbox placement and reputation from real mailbox data, and Competitive Tracker benchmarks your program against other brands. Neither requires self-hosting your sending infrastructure.

What happened to SparkPost?

SparkPost is now Bird Email. It's the same deliverability engine and the same team, now part of an API that also sends SMS, WhatsApp, and voice. If you sent on SparkPost, you're already on the Bird network.

Who is this for?

Teams with infrastructure or compliance requirements that call for running their own MTA, and teams that want independent visibility into inbox placement and competitive benchmarking rather than relying on their own send metrics alone.
