Subscriber Preview and Test Send

Subscriber Preview and Test in Email Studio is a rendering of an email as viewed by a recipient. After the initial subscriber preview, consider proceeding through the rest of the recipients to see previews for each subscriber. The preview feature doesn’t display in a particular operating system or email client.

Note Selecting a subscriber for preview does not send them an email. Preview and Test sends the test email only to the addresses you enter in the Recipients tab. Marketing Cloud Engagement uses the selected subscriber’s data strictly to render personalization and dynamic content.

To preview recipients for a data extension, the data extension must meet one of these criteria:

• Contains an email address field type
• Is linked to the subscriber table via the Subscriber ID
• Is linked to the subscriber table via the Subscriber Key

After you select a subscriber, you can use Test Send to send the email. For example, send the email to your own inbox to view how the email appears in your email client.

If you change the subscriber attributes in subscriber preview, unsubscribe from a test email that you send, or access the subscriber's profile center and make changes, those changes permanently apply to that subscriber.

Tip Create a test subscriber whose properties you can change as needed for previewing and testing links.

A test send counts as a send in the application and against the threshold you purchased. If the subscriber you select for the preview has a status of unsubscribed, bounced, or held the generated preview doesn’t deliver any test send. If sending to a data extension, you don’t see the status of that subscriber as that is kept at the All Subscribers level. The preview and test send appears to send, if that subscriber is unsubscribed, bounced, or held at the All Subscribers level the send doesn’t occur. The All Subscribers level contains the default status for data extensions. To see if the subscriber you chose is unsubscribed, search for the subscriber.
