# POST a Resend to Non-openers Campaign Activity

`POST /emails/activities/{campaign_activity_id}/non_opener_resends`

## Request

- Base URL: `https://api.cc.email/v3`
- URL: `https://api.cc.email/v3/emails/activities/{campaign_activity_id}/non_opener_resends`

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.
