When email is a regulatory obligation, 'probably delivered' is not a status.

Regulated senders carry three burdens ordinary senders don’t. First, delivery itself is often mandated: a disclosure notice that lands in spam may not satisfy the obligation, and a security alert that arrives late is a real harm. Second, evidence is mandatory. When an auditor or a dispute asks whether the notice was sent and delivered, the answer must be a record, not a recollection. Third, the channel itself is under attack. Finance brands are phishing’s favorite costume, which makes rigorous authentication (DMARC at enforcement, not parked at p=none) part of customer protection rather than just deliverability.

There is also a vendor-diligence dimension. Email infrastructure touches customer PII by definition, addresses at minimum, so it falls inside your third-party risk program: access controls, encryption posture, incident commitments, and crucially, what the vendor can see. Our answer to that last one is architectural. We never read or store message bodies or mailbox contents. The content of a statement email is not something we have access to. That makes the diligence conversation considerably shorter.

None of this requires exotic technology. It requires discipline applied consistently: enforced TLS, aligned authentication, isolated reputation for obligation-bearing mail, immutable delivery records, access logs on every administrative action. That is the default posture of our platform, not a premium tier.
