# Testing an Email with Multiple Email Clients
Building an email that displays consistently in different email clients can be a challenge. Device Preview in Dyspatch allows you to test an email for mobile, web, and desktop email clients so you can make sure your code is displaying as intended on a variety of platforms and devices.
## Device Testing an Email
Click **Preview** from the Email Builder to get to the Device Preview Page.
### Device Previews with Customer Profiles or Preview Data
You can use a Customer Profile to populate dynamic content for your device previews. If you are not using dynamic content, or are using data from this individual email's preview data, leave as **No Customer Profile**.
Click **Next**
Do not include personally identifiable information (PII) or other sensitive data in device tests. Including such information will negatively impact regulatory compliance and may compromise the security of your customer data.
### Select Which Email Clients to Preview
Mark the devices and clients you wish to preview your email on and click **Generate Previews**. A selection of most popular email clients are available under the **Preset Lists**.
## View Device Previews
Click on each box (thumbnail) within a category to get a full-sized view of the specific test device. On the full-sized view, you can click on the arrow buttons or use your arrow keys to navigate through all your generated device tests.
