# GET the HTML Preview of an Email Campaign Activity

`GET /emails/activities/{campaign_activity_id}/previews`

Use this method to get the HTML preview of an email campaign activity. The HTML preview allows you to verify how the email campaign activity will look before you send it to contacts.

Custom code emails (`format_type` 5) use the Constant Contact account owner's contact information to process contact, custom field, and account variables in the preview.

This method returns the HTML preview encoded as a JSON string. You will need to decode the string before you can use it as valid HTML.
