Integrate and deliver with confidence
With the REST API, you can send emails directly from your own software or application. It offers a simple and modern way to connect to our infrastructure without using SMTP. All communication happens over HTTPS with clear responses, so you always know whether a request was accepted, processed, or failed. This transparency makes delivery predictable and secure.
Manage and automate from your own stack
Beyond sending, the API lets you manage templates, domains, authentication, and event tracking from your own environment. You can automate routine tasks, keep configuration up to date, and trigger personalized, event driven emails for cases like orders, password resets, and alerts.
Insight and control
View delivery results, opens, clicks, and bounces in the dashboard or retrieve them with the API. Use these insights to troubleshoot quickly and improve performance across your entire email flow.
Quick to get started
Create an API key in your SMTPeter account, follow the examples in the documentation, and send your first message within minutes. The clear structure of the API works smoothly in any modern development environment.
