Deliverability & the Delivery Inspector

"It says delivered — but did it arrive?" is the question this module answers, continuously, for every channel.

The deliverability report

GET /v1/account/channel-deliverability (dashboard: Analytics → Deliverability) shows delivery rate, failure rate and click rate per channel over time, plus the email reputation report (/v1/account/deliverability): bounce rate, complaint rate, spam-trap indicators and domain authentication status, with thresholds marked so you can see how close to trouble you are, not just where you are today.

The Delivery Inspector

Every failed or delayed message can be opened in the Inspector — a plain-language timeline of exactly what happened:

10:41:02  Accepted (API) — queued for route DK-1
10:41:03  Submitted to vendor
10:41:19  Vendor status: REJECTED — code 33: sender not registered for destination
          → Explanation: Denmark requires alphanumeric sender registration.
          → Fix: register "Acme" under Settings → Senders, or send from a numeric sender.

No decoding cryptic carrier error codes at midnight. The Inspector translates vendor and carrier responses into the reason and the fix.

Vendor health & failover

The platform monitors each downstream vendor's live delivery performance per destination. If a route degrades — a vendor starts failing Danish traffic, say — sends automatically fail over to the next-best route, and the incident appears in Operations → Vendor health. Messages that ultimately fail land in a dead-letter queue for inspection and one-click retry (POST /v1/messages/ops/:id/retry) rather than vanishing.

Deliverability autopilot

Optionally, the platform acts on its own findings: pausing a campaign whose bounce rate spikes above a threshold, throttling volume to a domain showing deferrals, and alerting you with the reason. You define the guard rails; it pulls the brake faster than a human watching dashboards ever could.
