  • By default, email notifications use the watermark prefix MSG, but you can create a custom watermark prefix.

    Role required: admin

    About this task

    Any email notifications that are forwarded from one instance to another might be more easily distinguished with different prefixes for each instance. To avoid unintentionally triggering events in the wrong instance, create a unique watermark prefix for each instance.
    Note:
    Do not use colons (:) in custom watermark prefixes. Colons are a reserved character and may cause the watermark to be ignored.

    Procedure

    1. Navigate to All > System Definition > Number Maintenance.
    2. Open the MSG record in the Email Watermark [sys_watermark] table.
    3. Enter the unique Prefix for this instance.
    4. Click Update.

    Result

    Your custom watermark applies to all new email notifications. Email notifications that existed before you created a custom watermark keep the same watermarks as before.
