What the Email engine handles for you
02
Verify a sending domain
Add your domain and publish the requested DNS records. Domain setup includes verification and DKIM configuration; it does not guarantee inbox placement.
03
Version your email templates
Publish subject and body templates for each event. Locale and variant selection let you reuse the integration across different messages.
04
Investigate failed sends
Review SMTP responses and delivery attempts in the console. Transient failures use the configured retry policy, while permanent errors are recorded for investigation.

Before sending, verify your domain, configure an active email provider, and publish the event template. Managed SMTP needs administrator approval. Provider acceptance does not establish inbox placement or recipient engagement.
