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

EmailOctopus API: https://cotlet.dev/docs/api/emailoctopus.md

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

Access: write.

Edits the set-up fields of a campaign that has not been sent: name, subject, preview text (the line shown after the subject in the inbox), sender name and sender email address. Fields you leave out stay as they are. The tool does not touch the design or the HTML of the email. It reaches no one, so it needs no confirmation.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `campaign_id` | string | yes | Campaign ID from list_campaigns. |
| `name` | string | no | Internal name of the campaign; subscribers do not see it. |
| `subject` | string | no | Subject line. |
| `preview_text` | string | no | Preview text shown after the subject. |
| `from_name` | string | no | Sender name. |
| `from_email` | string | no | Sender email address verified in your account. |
