Who will operate your email infrastructure?
Choose the Bird Email API or SMTP relay when you want Bird to run the MTA and delivery infrastructure in the cloud while your team manages sending domains, Dedicated IPs, audiences, and templates. Choose PowerMTA or Momentum MTA when security, compliance, or custom routing policies require your team to run the MTA on-premises or in your own private cloud.
Match the product to the operating model.
Combine managed cloud sending or self-managed MTAs with inbox placement testing and competitive monitoring.

Momentum MTA: programmable on-prem and private-cloud delivery.
Run Momentum MTA on your own servers or private cloud when your operation needs custom policy hooks, multi-node clustering, and fine-grained traffic routing for high-volume sending.
