    Delivery events

    The request is only the beginning.

    Follow delivery events through webhooks so your application can respond to the outcome. An accepted request does not mean an email reached the inbox.

    1. 1. Send

      Your application submits an email through the API or SMTP.

    2. 2. Delivery

      Follow the delivery outcome for the message.

    3. 3. Webhook

      Receive an event at your configured endpoint.

    Explore webhooks
