# Resend campaign to non-openers

`POST /campaigns/{campaignId}/resend-to-non-openers`

Creates a draft that resends a sent campaign to everyone in the same audience who didn't open it. Reuses the original audience plus a "didn't open this campaign" rule. Only available 6 hours after the campaign finishes sending. The draft must be scheduled or sent separately.

## Path parameters

- `campaignId` string, required

## Response `200`

Non-opener resend draft created

- object
  - `success` boolean
  - `campaign` object
    - `id` string
    - `name` string
    - `type` 'email' | 'sms' — Delivery channel. SMS campaigns are created and managed from the dashboard: they carry no email, so `subject` and `blocks` come back empty, and the email-only endpoints (update, schedule, pause, resume, duplicate, resend to non-openers) reject them. Campaign stats and campaign events reject them too, since both read email engagement.
    - `subject` string
    - `emailId` string, nullable — ID of the new resend email.
    - `emailPreset` 'branded' | 'minimal', nullable — Per-email Style > Format, derived from the stored blocks. `branded` renders the company logo and the full footer; `minimal` renders no logo and the simple footer. Null when the entire email is a single raw HTML block, which has no Sequenzy format. Sequence steps, campaigns, transactional templates, and saved templates all report this field, so chrome can be compared across emails without rendering them.
    - `status` 'draft' | 'scheduled' | 'waiting_approval' | 'rejected' | 'sending' | 'paused' | 'sent' | 'cancelled' — Campaign status. `waiting_approval` means the campaign is held for safety review and is not sending; this is most common on new accounts and recently registered sending domains. See https://docs.sequenzy.com/concepts/campaigns#safety-review
    - `rejectionComment` string, nullable — Reviewer feedback when the campaign status is rejected. Stays null while a campaign is still in waiting_approval.
    - `trackingCode` string, nullable — Campaign tracking code available to UTM templates as `{{campaign.trackingCode}}`.
    - `labels` string[] — Label names assigned to this campaign.
    - `scheduledAt` string, date-time, nullable
    - `sentAt` string, date-time, nullable
    - `createdAt` string, date-time
    - `preheader` string
    - `preheaderText` string — Compatibility alias for preheader.
    - `blocks` EmailBlock[]
      - `id` string
      - `type` 'text' | 'html' | 'heading' | 'list' | 'button' | 'spacer' | 'divider' | 'image' | 'columns' | 'conditional-group' | 'repeat' | 'card' | 'cta' | 'social' | 'logo' | 'header' | 'footer' | 'video' | 'product' | 'discount-code' | 'code' | 'countdown' | 'hero' | 'testimonial' | 'gallery' | 'badge' | 'table' | 'features' | 'image-card' | 'pricing' | 'author' | 'article' | 'rating' | 'stats' | 'steps' | 'product-grid' | 'poll', required
      - `content` string — Content for text, html, and heading-like blocks.
      - `styles` object — Per-block visual styles. For compatibility, style fields such as backgroundColor, backgroundOpacity, borderColor, borderWidth, and borderRadius can also be supplied at the block top level and are normalized into this object.
        - `paddingTop` number
        - `paddingBottom` number
        - `paddingLeft` number
        - `paddingRight` number
        - `backgroundColor` string
        - `backgroundOpacity` number — Background opacity percentage from 0 to 100.
        - `textColor` string
        - `textAlign` 'left' | 'center' | 'right'
        - `borderRadius` number
        - `borderColor` string
        - `borderWidth` number
        - `bleed` boolean — Stretch the block edge-to-edge across the email container. Top-level blocks only.
      - `conditions` object[] — Optional per-block display rules. The block renders only when every rule matches. The same shape is used for a conditional-group block's top-level `conditions`.
        - `id` string, required
        - `field` 'variable' | 'attribute' | 'email' | 'firstName' | 'lastName', required — `variable` resolves a merge-tag path from the transactional send `variables` or an automation `event` payload (nested paths like `order.total` or `event.plan` work). `attribute` reads a stored subscriber attribute. `email`, `firstName`, and `lastName` read core subscriber fields.
        - `operator` 'is' | 'is_not' | 'contains' | 'not_contains' | 'gt' | 'gte' | 'lt' | 'lte' | 'is_empty' | 'is_not_empty', required
        - `value` string, required — For `variable` and `attribute`, use `name:value` - the part before the colon is the variable path or attribute name, and the part after it is the comparison value. For `email`, `firstName`, and `lastName`, provide the plain comparison string.
    - `campaignData` object, nullable
    - `computedLists` object[]
    - `targetLists` object, nullable — Saved campaign audience, or null when targeting is still unset and scheduling will fall back to all active subscribers.
    - `senderProfileId` string
    - `fromName` string, nullable
    - `fromEmail` string, email, nullable
    - `replyProfileId` string, nullable
    - `replyToName` string, nullable
    - `replyToEmail` string, email, nullable
    - `ccEmails` string[], nullable — Addresses CC'd on every recipient's email for this campaign.
    - `bccEmails` string[], nullable — Addresses BCC'd on every recipient's email for this campaign.
  - `estimatedNonOpenerCount` integer — Estimated number of subscribers who haven't opened the original campaign.
