On the Review step, FluxoMail shows a preflight card to help you send safely:
  • Domain verified — checks identity + DKIM
  • One-click unsubscribe — checks that an HTTP unsubscribe endpoint is configured
  • Delivery rate (7d) — compared to your policy target (default >= 97%)
  • Complaint rate (7d) — compared to your policy budget (default <= 0.3%)
Fixes
  • Domain not verified: complete verification under Domains
  • Missing unsubscribe: add an HTTP unsubscribe URL under Settings
  • Low delivery or high complaints: pause bulk sends, adjust content, review reputation
Notes Preflight reads org metrics for the last 7 days and the active bulk policy thresholds where applicable.
