📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win
Move flush() and duplicate handling to CampaignProcessorMessageHandler.
The src/Domain/** rule prohibits flush() in CampaignAdminNotifier, while the message handler is the orchestration boundary. Keep persist() in the notifier. Flush immediately after notifyStart() and catch UniqueConstraintViolationException there. Do not use the existing conditional flush at line 111, because normal campaigns do not reach it. This preserves the current order: notifications are sent before start_notified is finalized, and duplicate rows remain ignored.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
Batch flush() in CampaignProcessorMessageHandler.
CampaignEmailSender flushes once per recipient, and invalid-email handling flushes twice. Remove these flush() calls and keep only the entity mutations in the sender. Flush once in the handler after normal, requeue, and exception paths complete. This preserves pending status changes and follows the src/Domain/** persistence rule.

Move flush() out of MessageStatusUpdater and cover every handler exit.
src/Domain/** must not finalize Doctrine state from a domain service. Remove the EntityManagerInterface dependency from MessageStatusUpdater. Flush in CampaignProcessorMessageHandler on normal completion, the precache-failure return, the requeue path, and exceptions from CampaignSendingLoop::run() so Suspended, InProcess, and Sent statuses remain persisted. The CampaignEmailSender paths already flush the following UserMessage update after changing the campaign status.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use the standard translation placeholder syntax.
CampaignProcessorMessageHandler passes ['error' => $exception->getMessage()], but this messages catalogue does not substitute {error}. The error log will contain the literal {error} instead of the precache failure.
Use %error% in this trans-unit and pass ['%error%' => $exception->getMessage()] in the handler.

Do not continue after a failed notification-marker flush.
MessageData uses (id, name) as a composite primary key, so a duplicate start_notified marker can raise UniqueConstraintViolationException. The handler catches and logs it, but Doctrine ORM 3.3 closes the shared autowired EntityManagerInterface after the failed flush. CampaignSendingLoop then reaches CampaignEmailSender::updateUserMessageStatus(), whose flush uses that closed manager.
Make the marker write race-safe and idempotent, or fail and retry the message with a fresh manager. Do not continue processing with the closed manager.
