Inbox Lens — email deliverability audit from a paste

Paste an email — subject, HTML or plain-text body, optionally your SPF/DKIM/DMARC records — and get an expert deliverability audit: an inbox/risky/spam verdict, severity-ranked findings each with the corrected record, header or copy, a scored twelve-item checklist, a five-area health check, and your own email rewritten to land. A free instant prescan flags spam-trigger phrasing, missing unsubscribe, image-heavy bodies and broken auth records before you run anything. Derived from @sickn33/email-systems.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
