Why teams pick it

  • API key as password

    Use your API key as the SMTP password, no extra credentials needed.

  • Scope-checked auth

    Permission scopes are validated before any message is accepted.

  • Full MIME parsing

    MIME is parsed and fed into the same queue-backed send pipeline.

  • Identical observability

    Tracking, analytics, and webhooks work identically to REST sends.
