When using your data extensions for an email send, there are a few things to keep in mind:
- You can select as many data extensions as you need when sending an email. If you have multiple audiences to communicate with on a single email, it is fine to have separate data sets in multiple data extensions.
- If your data extension has additional data in it other than name and email, and you'd like to filter your data to segment your audience, you can learn how to do that.
