Notification content

Each notification method has a content limit. To ensure successful alarm notifications, the system may truncate the excess part. However, the content integrity and successful sending depend on the truncated content and the notification method. For example, if the truncated content is in invalid Markdown or HTML format, the notification may fail. For SMS and voice messages, truncation does not cause notification failures.

• SMS
