A self-operated model needs deployment, capacity, reputation management and recovery ownership. Evaluate the current release, license and support scope against a representative workload.
Evaluate PowerMTA ↗Who will operate your email infrastructure?
Choose the Bird Email API or SMTP relay when you want hosted sending. Choose PowerMTA or Momentum when your team needs to operate the MTA itself. Inbox Insights and Competitive Insights address monitoring and market intelligence. Each path has its own setup and commercial requirements.
Prepare your enterprise rollout.
Give engineering, security and procurement the information they need to evaluate your email service.
Security and data processing.
Review security information and request available reports in the Bird Trust Center. Your procurement team can review the Data Processing Agreement and subprocessor list before agreeing the scope of service.
Availability and support.
Check current operations on the service status page. Discuss required availability, support coverage, response targets and escalation with our team, and confirm the commitments that apply to your service in your agreement.
A migration you can verify.
Map your API calls, templates, domains and recipient restrictions before moving traffic. Our migration guides cover provider differences, sandbox testing and cutover checks. Bring your current volume and peak traffic to the migration discussion.
Capacity and commercial terms.
Compare included volume, domain limits, webhook endpoints and overage in the published email plans. Discuss dedicated IPs, peaks and invoicing with our team. Hosted sending, self-managed MTAs and monitoring products have their own setup and commercial requirements.

Contact salesQuestions about enterprise email
Can we use the Email API without operating our own infrastructure?
Yes. Bird operates the sending infrastructure for the hosted Email API and SMTP relay. Your team integrates the service, configures sending domains and manages recipient permissions. PowerMTA and Momentum are separate options for teams that want to operate an MTA.
How do we evaluate availability and support?
Discuss the availability, response targets, support hours and escalation your application needs with our email team. Confirm the agreed commitments and any remedies in your service agreement before moving production traffic. The service status page reports current operations.
Where can our security team review data protection information?
Use the Bird Trust Center for security information and available reports. Review the Data Processing Agreement and subprocessor list, then confirm processing locations, retention and access requirements for your selected services with our team.
What's the difference between Momentum MTA and PowerMTA?
Both are on-prem MTAs you run yourself instead of sending through our 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.
Who is this for, and do I need to run my own MTA to use Inbox Insights or Competitive Insights?
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. The first group runs Momentum MTA or PowerMTA. The second group uses Inbox Insights, which estimates inbox placement and supports campaign seed tests, or Competitive Insights, which benchmarks your program against other brands, and neither of those requires you to self-host anything.
