Hundreds of emails sent out but no entries recorded

Yesterday my client had 474 emails sent to him informing him of new guest entries - of which there were none recorded in the system/DB. Any ideas what might be causing this?

FYI, a friend has said "It may send a notification if event_after_save_entry is triggered elsewhere", in reference to:

Event::on(SaveController::class, SaveController::EVENT_AFTER_SAVE_ENTRY, function(SaveEvent $e) {
    $entry = $e->entry;
    GuestEntriesNotification::$plugin->guestEntriesNotificationService->sendNotification($entry);
});
