# The Mailgun alternative for transactional email | Bird

Mailgun is a capable developer email platform with a few features Bird does not match. Bird runs on SparkPost, the platform it acquired in 2021 that carries about 40% of the world’s commercial email, and adds idempotency, 30-day message history, lower cost at higher volumes, and SMS and voice on the same API. Here is where each one fits. See the Bird Email API for the full surface.
