POST a Resend to Non-openers Campaign Activity

Use this POST method to resend a primary campaign activity to contacts that did not open a campaign activity that has a current status of Draft, Scheduled, or Done. You can only create one resend activity per email campaign.

After an email campaign activity is sent to contacts, Constant Contact waits the specified number of delay_days or delay_minutes (properties are mutually exclusive) before resending to non-openers. If you set both delay_days or delay_minutes, delay_minutes is ignored in the request. You can resend to non-openers a minimum of twelve hours (720 minutes) and a maximum of up to 10 days (or 10 x 1440 minutes) after the initial send date.
