# Personalization using message namespace properties

Message namespace properties are dynamic values that are automatically populated based on the details of a messaging campaign.

These properties are the message name, platforms, send date, [Push ID](https://www.airship.com/docs/reference/glossary/#push_id), and [Campaign Categories](https://www.airship.com/docs/reference/glossary/#campaign_categories). They serve a crucial role in personalizing messages and tailoring content by allowing you to dynamically adjust [URL Parameters](https://www.airship.com/docs/reference/glossary/#url_parameters) and implement conditional logic using [Handlebars](https://www.airship.com/docs/reference/glossary/#handlebars). Using these properties, you can create more relevant and targeted messaging experiences for your audience. You can also use [Text](https://www.airship.com/docs/guides/personalization/handlebars/text-helpers/) and [Date and time](https://www.airship.com/docs/guides/personalization/handlebars/date-time-helpers/) helpers to transform content in your Handlebars expressions.

The properties are available for personalization for all channels and message types except for [In-App Automations](https://www.airship.com/docs/reference/glossary/#iaa) and [Scenes](https://www.airship.com/docs/reference/glossary/#scene).
