 ## Важно про окончание подписки
 
-Если пользователь привязал email к Telegram-аккаунту, уведомления об окончании подписки не дублируются в почту полностью. Сейчас email получает только напоминание за 3 дня до окончания, и только когда оно пришло из Remnawave Panel webhook `user.expires_in_72_hours`. Остальные стадии - 48 часов, 24 часа, почасовое предупреждение, день окончания и уведомление через сутки после окончания - отправляются только в Telegram.
+Если пользователь привязал email к Telegram-аккаунту, уведомления об окончании подписки дублируются в оба канала: Telegram и email. Если привязан только Telegram - уйдет только Telegram. Если есть только email - уйдет только email.
 
-Если Remnawave webhook не настроен или используется только локальный `SubscriptionNotificationWorker`, даже напоминание за 3 дня уйдет только в Telegram.
+Email-доставка требует одновременно:
 
-## Рекомендации по синхронизации каналов
+- `SUBSCRIPTION_EMAIL_NOTIFICATIONS_ENABLED=True`;
+- настроенный SMTP-контур;
+- email у пользователя.
 
-- Для пользовательских уведомлений о подписке лучше выбрать единую политику: либо email дублирует все важные стадии, либо email используется только для мягкого раннего напоминания за 3 дня. Текущее поведение ближе ко второму варианту.
+## Синхронизация каналов
-- Если нужно полное дублирование, стоит вынести отправку lifecycle-уведомлений подписки в общий сервис и вызывать его и из Remnawave webhook, и из локального worker. Тогда одна и та же стадия будет одинаково обрабатываться для Telegram и email.
+
-- Дедупликацию лучше вести отдельно по каналу, например `before_3d:telegram` и `before_3d:email`, чтобы сбой Telegram не блокировал email и наоборот.
+Remnawave webhook и локальный `SubscriptionNotificationWorker` используют общий сервис отправки и общую таблицу дедупликации `subscription_notifications`.
-- Для email-канала стоит добавить отдельный флаг вроде `SUBSCRIPTION_EMAIL_NOTIFICATIONS_ENABLED` и, при необходимости, настройки по стадиям: за 3 дня, за 1 день, в день окончания, после окончания.
+
-- Если одновременно включены Remnawave webhook и локальный worker, стоит синхронизировать их через одну таблицу отправленных уведомлений. Сейчас worker пишет историю `subscription_notifications`, а webhook-уведомления обрабатываются отдельно, поэтому при близких расписаниях возможны повторы в Telegram.
+Дедупликация ведется отдельно по каналам: например, `before_3d:telegram` и `before_3d:email`. Благодаря этому сбой одного канала не блокирует второй, а повторное событие из webhook или worker не отправляет уже доставленное уведомление повторно.
+
+Старые записи без канала, например `before_3d`, считаются Telegram-историей. Они блокируют повторное Telegram-сообщение, но не мешают отправить email после обновления.
