Rules the system enforces

  • Every attempted row is marked sent or failed; failures count against the rolling attempt limit.
  • The module does not automatically requeue failed recipients in the supplied release.

How to confirm it worked

  • The requested record, output or setting is created or updated through the supported module flow.
  • Any related status, count, email, audit/event, PDF/file or queue evidence agrees with the source action.
  • An error message is investigated rather than bypassed.

Security, privacy and operational checks

  • Apply least privilege and verify the correct customer, lead, sales document or recipient before processing.
  • Protect public tokens, recipient data, IP/browser evidence, templates and exported files according to organisational policy.
  • Test configuration changes with controlled records before production-wide use.
  • Retain or delete evidence only under an authorised retention process.
