SkyMailr Certified Operator / Administrator

What you'll be able to do

• ✓Tour the staff-only operator interface, learn what each page covers, and master the tenant switcher so context-sensitive actions always run against the right tenant.
• ✓Search and inspect messages, read the immutable event log, retry failed sends, cancel queued ones, and diagnose by status plus error code with a clear cause-to-fix table.
• ✓Learn how operator test sends run through the real delivery pipeline so suppression, sender resolution, and the domain gate all still apply, and how the LLM Template Studio drafts subject and body copy that only ships after you approve it.
• ✓Run a tenant from the operator side: manage settings, domains, sender profiles, and keys; read the Deliverability tab for DNS/auth readiness; and use the Sending-risk tab to interpret the risk score, 24h metrics, and pause state. Learn how auto-pause and manual pause differ in scope and source, and why automation will never override a manual pause.
• ✓How SkyMailr decides each tenant's per-minute send cap: a per-tenant override beats the plan default, which beats a global floor (30/min by default) — all tunable on the operator Limits page without a redeploy. Plus how unlimited internal plans bypass the floor and how per-domain caps support warm-up.
• ✓Learn how operators view global and per-tenant suppression lists, manually suppress an abusive or spam-trap address, and safely remove a suppression — leaving a tamper-evident audit trail behind.
• ✓Learn what the provider health check really proves (the key works, not that mail lands), and how SkyMailr ingests inbound webhooks: store raw, validate the signature, normalize, map by message id, update status, and trip the reputation pause on bounces and complaints.
• ✓SkyMailr hands mail to Postal and then goes blind until Postal calls back with a delivery event. This module teaches what webhooks are, what each outcome (delivered, hard bounce, soft bounce, complaint) automatically triggers, why a real audit found the entire reactive layer dormant, and how to wire and verify Postal -> SkyMailr webhooks.
• ✓Learn the five SkyMailr account roles and what each one gates, why invites are role-scoped, and how the three separate auth worlds — customer portal, staff operator UI, and tenant API key — never overlap.
• ✓How SkyMailr keeps each tenant's data walled off, why API keys are stored hashed and shown only once, and the concrete steps to harden the admin surface and rotate a leaked key.
• ✓Learn how SkyMailr's dispatch engine runs on Celery and Redis, where Postal lives and who administers it, then walk four real incident playbooks: duplicate-send storms, blank-sender failures, spam-folder triage, and complaint spikes.
• ✓A real Tomeo incident teaches the layered diagnostic method: separate "never left" from "soft-failed/retried" from "permanent bounce," then assign each symptom to its true owner instead of blaming a single culprit.
• ✓A hands-on operator lab: inspect a real message's status, headers and events; add a manual suppression and learn when it's right; check provider health the correct way; and read the webhook (ops) event feed — practising the operator mindset of confirm-before-acting and status-vs-delivery truth.
• ✓Earn a shareable, publicly verifiable certificate of completion.
