# Message Activities

Messaging activities include email, SMS, LINE message, push notification, inbox message, in-app message, or any other form of content sent to contacts. To provide a mix of information about your brand or your product, vary the message content. Create message content before you build a journey.

You can use any data stored in Marketing Cloud Engagement, including journey data, for personalization strings. Make sure that the attribute names used in personalization strings and dynamic content match the attribute names in the data extension exactly. Define a default value for every attribute so that the personalization string is never blank. If you insert a personalization string and the subscriber attribute isn't populated, the string is blank in the email. For example, set the First Name field default to **Customer** so that Dear Customer appears in the message if that field is blank in the data extension.

![Tip](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_journeys_and_automations-264-0-0-production-enus/e08cdd71-c1c1-4ae5-a5e9-8a6dad583ad4/images/icon_tip.png)

Tip Make sure to map attributes for personalization or dynamic content to the appropriate data source. If you use journey data and contact data, the values in the journey data are static, while contact data can change.
