+Send Email or Telegram notifications on success or failed backup.
+
+### Email
+To send out email notifications on failed backup runs, provide SMTP credentials, a sender and a recipient:
+
+```yaml

+
+### Customize notifications
+
+The body of the notifications can be tailored to your needs using Go templates.
+Template sources must be mounted inside the container in /config/templates:
+
+- email.template: Email notification template
+- telegram.template: Telegram notification template
+- error.template: Error notification template
+
+### Data
+
+Here is a list of all data passed to the template:
+- `Database` : Database name
+- `StartTime`: Backup start time process
+- `EndTime`: Backup start time process
+- `Storage`: Backup storage
+- `BackupLocation`: Backup location
+- `BackupSize`: Backup size
