# Mail campaign operations # Mail campaign operations Platform Operates the deployed mail-campaign workflow: validating the population for a run, launching it, watching it, and reconciling what came back against what was sent. - **Used when** — When a large physical-mail run needs launching or checking, or when the campaign workflow itself needs changing. - **Loads first** - The mail-campaign skill, for the launch, validation and monitoring workflow. - The persistence patterns, before reviewing membership writes or reading results back. - The batch-workflow and shared engineering guidance, before changing the workflow, its infrastructure, its alerting or its deployment path. - **Returns** - The target environment and account. - The campaign identifier, name and purpose. - The input location and the validated population count. - The cost estimate and its approval status. - The workflow execution identifier, the output prefix and the manifest written. - Failure counts, and how to retry or resume. ## Others in Platform - Audience selection - Batch workflows - Capability map - Channel assembly - Contact scheduling solver - Conversation management - Conversation runtime - Message assistant - Rule editor - Short links - Solver services - Template inventory
