Message IDs Reformat on Fan Outs

Mar 27, 2024

A new feature was implemented where Message IDs for array recipients and list-based recipients were suffixed with `@{index}` and `@{userId},` respectively. This change followed customer feedback and aimed to improve traceability by aligning Message IDs with their corresponding Request IDs. This update was fully rolled out over the past two months and recently enabled for ad hoc requests, bulk sends, and automations.
