SkyMailr Certified Professional

What you'll be able to do

• ✓Follow one message from your API call to a delivered email, and learn the six places SkyMailr can stop a send before it ever reaches the email provider.
• ✓Go beyond authentication: FCrDNS/PTR as the IP-trust check, the List-Unsubscribe and List-Id headers SkyMailr stamps on bulk mail, Google Postmaster Tools as read-only monitoring, and why warm-up and engagement are the levers that actually move deliverability.
• ✓Learn how SkyMailr stops sending to addresses that bounced, complained, or opted out — the suppression list vs unsubscribe records, what hard bounces and complaints trigger, the one-click unsubscribe, and the legal must-haves you still own.
• ✓How SkyMailr automatically guards your sender reputation: it watches 24-hour bounce, complaint, and failure rates plus volume spikes and auto-pauses sending by scope, while a separate rate limit and optional per-domain caps control how fast you send.
• ✓SkyMailr runs two complementary safety nets so a buggy caller never floods a recipient: an explicit idempotency key you control, and an automatic content-based duplicate-send guard. Plus fail-closed sending, which refuses to invent a fake From address.
• ✓A guided tour of every SkyMailr API endpoint group — send, message, templates, workflows, suppressions, unsubscribe, and health — plus how Bearer auth scopes you to one tenant and why a fresh send returns 201 while a replayed one returns 200.
• ✓Register outbound webhook endpoints to receive message events, learn the event types including the message-less unsubscribed event, always verify the HMAC signature and timestamp before trusting a payload, and use skip_unsubscribe_footer when your app renders its own opt-out link.
• ✓Learn how a SkyMailr workflow strings together ordered steps into an automated lifecycle journey: how you enroll a recipient with template_context, how a Celery beat schedule advances each execution, how send steps reuse the same suppression-and-render pipeline, and why the far-future-wait footgun makes the dedup guard essential.
• ✓How SkyMailr plans, quotas, and the unlimited internal plan shape what an account can do — and the gates every send must pass before a message is created.
• ✓A hands-on lab: create and approve an email template, send it through the Academy Sandbox with one curl command, then wire up an outbound webhook and watch a real delivery event land as JSON.
• ✓Earn a shareable, publicly verifiable certificate of completion.
