Use this method to return a specific email campaign activity. Each email campaign activity contains the email content, metadata, and styling information of an email. Email campaign activities can also contain either contact lists or segments. Constant Contact uses this information to determine who to send the email campaign activity to when you schedule it. You cannot get email campaign activities that have a REMOVED status.

Use this method to update an email campaign activity by including the complete email campaign activity with your changes in the request body. The request body requires the from_name, from_email, reply_to_email, and subject properties.

You can only update email campaign activities that have the primary_email role and that are in DRAFT or Done status. When you use a PUT method to update a resource, the V3 API overwrites any properties that are missing in the request body. However, the V3 API does not overwrite subresources that you omit in the request body or missing properties in subresources. This method considers physical_address_in_footer, document_properties, html_content, and permalink_url subresources of the email campaign activity.
