Most providers report "sent" when they accepted your API call. We run Postfix, so a 250 from the receiving host becomes delivered — and a hard bounce or complaint auto-suppresses before the next send. Inbox-vs-spam seed tests are coming; we don't sell them as live.
Each one is live in production. The suite that is not live is listed below, not mixed in.
Auto-generated DKIM keys, derived SPF and DMARC, optional custom MAIL FROM. One-click DNS publishing on supported providers, copy-paste records for any registrar, and live re-verification. Unverified domains cannot send.
Hard bounces and complaints auto-suppress, and the per-project list is enforced pre-send. Optional /verify checks syntax, MX, disposable and role accounts, and Spamhaus DBL before a message leaves.
Bounce and complaint arrive via DSN/ARF. Delivered is derived from Postfix status=sent (250 …) — not from hoping a receiver honors NOTIFY=SUCCESS. Signed webhooks fire for sent, delivered, bounced, and complained.
List-Unsubscribe and RFC 8058 one-click headers are injected on mail we relay. DMARC records are generated at domain setup with a guided path from p=none toward enforcement.
| Requirement | Today |
|---|---|
| SPF + DKIM aligned | Keys and records generated at domain setup; sending is blocked until the domain is verified. |
| DMARC published | DMARC derived automatically with a guided path from p=none to enforcement. |
| One-click unsubscribe | List-Unsubscribe and one-click headers injected; processed immediately. |
| Complaint rate under 0.3% | We record complaints and show the rate on the dashboard. Automatic throttle / kill-switch is not live yet. |
| Forward & reverse DNS | We operate the sending hosts. PTR cutover for the public sending IP is an ops task, not a self-serve product. |
These are the paid, defensible layer. They are not in the product today.
Per-tenant or per-stream IPs so a campaign cannot poison password resets. Today every tenant shares the mail server we operate.
Volume ramps per IP per day that react to bounce and complaint signals.
Inbox / spam / missing, per mailbox provider. Until then we report accepted-by-receiver, not folder placement.
Platform operators already see DNSBL checks in God Mode. Tenant-facing listing alerts are not shipped.
Parsed aggregate reports — who sends as you, and where alignment fails.
Signup screening, send-pattern anomaly detection, and a complaint-rate kill-switch. Plan send caps are already enforced.
Authenticate a domain in minutes, send through a mail server we operate, and watch delivered / bounced / complained on the same dashboard. Drop-in compatible API — change the base URL and you're sending.
