# Resume Sending Email Campaign

POST /api/v2/projects/{projectId}/email-campaigns/{campaignId}/resume

Resumes a paused campaign. Sending continues from the contact pagination cursor where it stopped, so recipients already sent to are not emailed twice. Requires sufficient project balance and an unblocked sender, the same as Send Email Campaign.

## Request

- projectId: string, path, required — ID of the project that owns the campaign.
- campaignId: string, path, required — ID of the paused campaign to resume.

## Response

- 200: Successful response
