Courier provides a powerful drag-and-drop template builder with options for white-labeling. Preview and test your Mailgun emails in a fully rendered format right in the browser.
Tracking down what went wrong with a missed or accidentally sent notification is a huge pain. Courier’s unified logs tie together everything that happens before you call the Mailgun API with everything that happens after, making this process easier for engineering and support.
Courier allows you to build complex email sequences on top of the Mailgun API. You can use our API or drag-and-drop editor to fetch data, delay steps, send to lists, and more.
