Choose the [Bird Email API](/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. ## Match the product to the operating model. Hosted sending, self-managed MTAs and monitoring solve different parts of an email program. - **01** Hosted email by API or SMTP. Connect your application to [Bird Email](/email-api) or use [SMTP relay](/email-api/features/smtp) with your existing mail client. Bird operates the sending infrastructure; your team manages its domains, audiences and sending practices. - **02** Momentum MTA: customizable, on-prem sending. [Momentum MTA](/email-api/features/momentum) gives you customizable workflows and routing for high-volume sending, running on infrastructure you control. - **03** PowerMTA: run it on your own servers or any public cloud. [PowerMTA](/email-api/features/power-mta) sends high-volume, business-critical email from your own servers or any public cloud, such as AWS or Azure. - **04** Inbox Insights: see where you're actually landing. [Inbox Insights](/email-api/features/inbox-insights) measures estimated inbox placement for your verified domains and provides seed tests for campaigns. Keep these measurements distinct from receiving-server acceptance. - **05** Competitive Insights: benchmark against the market. [Competitive Insights](/email-api/features/competitive-insights) lets you watch brands and compare captured campaigns, sending cadence and panel-estimated placement. Coverage depends on what the panel observes for each brand’s tracked domain. - **06** Built by the SparkPost team. [Explore SparkPost and Bird Email](/email-api/features/sparkpost): bring your sending, authentication and delivery workflows into Bird, with a migration plan that fits your existing integration. 161% Increase in email open rates reported in Zillow’s customer story.

Its team reported a 161% increase in open rates in the first month. Planning a migration or a higher-volume send? ## Questions about enterprise email ### 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. ## Choose your operating model Explore hosted sending, self-managed infrastructure and monitoring. - [Momentum MTA](/email-api/features/momentum): Customize message processing and delivery policies on infrastructure you operate. - [PowerMTA](/email-api/features/power-mta): Control virtual MTAs, sending IPs and queues on your own servers or in a public cloud. - [Inbox Insights](/email-api/features/inbox-insights): Seed-measured inbox placement and campaign tests for your verified domains. - [Competitive Insights](/email-api/features/competitive-insights): Benchmark your email program against other brands in your industry. - [SparkPost](/email-api/features/sparkpost): SparkPost is now Bird Email: same deliverability engine, one API. - [Email API overview](/email-api): The full Email API: sending, deliverability, IPs, suppression, analytics, and broadcasts. ## Plan email around your infrastructure.
