Acceptable use policy

Email only works if the network can trust senders. This policy is short because the rule is simple: send wanted mail, honestly identified.

Not allowed

• Unsolicited bulk email. Purchased, scraped, or harvested lists; sending without consent; re-adding unsubscribers.
• Deception. Forged senders, misleading subjects, phishing, impersonation.
• Malicious content. Malware, credential harvesting, link-cloaked exploits.
• Illegal content under EU law or the law of your sending jurisdiction.
• Abuse of the platform — attempting to bypass suppression, quotas, content policy, or another tenant's isolation.

How enforcement works

Most enforcement is structural: every send — REST, SMTP, browser SDK, compatibility endpoints, broadcasts, automations — passes through one admission gate: idempotency, suppression, quota, and content policy in a single checkpoint no ingress can skip. Complaint feedback loops suppress a recipient on the first spam report; reputation breakers throttle sending patterns that look like abuse before mailbox providers have to react.

When policy enforcement triggers, a human reviews it. You'll get specifics — what tripped, on which sends — not a form letter. Appeals: hello@emailfast.dev.
