# Update campaign

> Change the name, subject or sender of a draft campaign. Inputs, cURL, Python and Node.js examples and an example response.

Source: https://cotlet.dev/docs/api/mailjet/update_campaign

Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Change the name, subject or sender of a draft campaign.

Mailjet API: https://cotlet.dev/docs/api/mailjet.md

`PATCH https://cotlet.dev/api/v1/mailjet/campaigns/{campaign_id}`

Access: write.

Sets the campaign name, the subject line and the From name and address of a draft. A scheduled or sent campaign cannot be edited and returns an error. The sender address must be one you may use in Mailjet. The design is not touched. The change reaches no one and is undone by calling the tool again, so it does not wait for your OK.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `campaign_id` | integer | yes | Campaign ID from list_campaigns. |
| `name` | string | no | Campaign name. Only you see it. |
| `subject` | string | no | Subject line, up to 100 characters. |
| `sender_name` | string | no | From name. |
| `sender_email` | string | no | From address you own or manage in Mailjet. |
