# Use Einstein-Tested Content in Your Emails

Test your content before you send it. You can test up to 32 images at a time.

![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_content_creation-264-0-0-production-enus/453b15fc-ab47-40df-8f11-8a7b92c8d0cd/images/icon_note.png)

Note Before you get started, set up your [content test experiment](https://help.salesforce.com/s/articleView?id=mktg.mc_pb_einstein_content_selection.htm&language=en_US).

Send an equal number of messages in your test, or tell Einstein to send the winning content asset to more recipients. When you add the Content Test content block to a message, you select an in-progress content test that was created in Einstein Content Selection.

1. Drag ![Einstein Content Testing Icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_content_creation-264-0-0-production-enus/453b15fc-ab47-40df-8f11-8a7b92c8d0cd/mc_content_creation/images/mc_ceb_ECS_content_testing.PNG) into your message.
2. Search for and select a test that is in progress.
    
    You can’t select a draft, completed, or archived content test.
3. To change the test settings or add an image, expand the test summary.
    1. To edit the settings, click ![arrow icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_content_creation-264-0-0-production-enus/453b15fc-ab47-40df-8f11-8a7b92c8d0cd/mc_content_creation/images/mc_pb_down_arrow_icon.png) and select **Edit**.
    2. To prevent Einstein from selecting an image in the test, click ![the trashcan icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_content_creation-264-0-0-production-enus/453b15fc-ab47-40df-8f11-8a7b92c8d0cd/mc_content_creation/images/mc_jb_delete_button.png).
4. Click **Done**.
    
    An image that’s included in the test appears in the content block.
