Security
Designed for trust
Transactional email only works when people can trust it. Our delivery practices are built to keep these messages authentic, protected from abuse, and focused on the action they relate to.
Authenticated sending
Messages are sent from authenticated infrastructure, so mail providers and recipients can confirm where they came from.
Abuse prevention
Sending is limited to authorized business customers, and activity is reviewed to detect and stop misuse.
Message integrity
Messages stay focused on their purpose — verification and account security — and are delivered over encrypted connections wherever receiving servers support it.
