Getting Started

Welcome to SMTPD!

Before you can start using the SMTPD you'll need to create an account.

You can do that directly via the API of from our sign-up form at https://app.smtpd.dev/signup.

Once you've created an account all features are automatically enabled except sending, which requires verifcation from our support team. They will reach our via email to confirm your details before sending is enabled.

Our API is organized around REST, has predictable resource-oriented URLs, accepts JSON-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

Before you can use the SMTPD REST APIs, you will need to have a valid API key.

IMPORTANT! Make sure to copy and paste the API key when it is displayed after saving. The whole API key is shown ONE TIME ONLY. After navigating away from that page recovery of a lost key is impossible. Keep your API keys in a safe and secure place. Treat them like passwords and never share them with anyone.
