Audit and fix email deliverability: SPF, DKIM, DMARC, reputation, bounces and complaints, list hygiene, unsubscribe compliance. Use when "emails go to spam", "set up SPF/DKIM", or "check deliverability". Templates → design-email.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# enhance-email-deliverability — Inbox placement & lawful send **Degree of freedom: MIXED.** Scoring auth/hygiene `[HIGH freedom]`; DNS/config apply `[LOW freedom — after approval]`. Audit-and-fix.

How to install
mdr add kensaurus/cursor-kenji/enhance-email-deliverability@sha256:5cc3a595ff01a7dfThe line at the top of this page pins the label git:20260923.68c095e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
