Add a subscriber to a Sendy list, then create and send a campaign to the list.

Add a subscriber to a Sendy list, then create and send a campaign to the list.

## Setup

Use a trusted HTTPS Sendy installation with its sending cron configured. The campaign is sent to the entire selected list, not only the subscriber added by this run. Use a list whose members agreed to receive the campaign and check its content and recipients before running. Sendy list settings control whether a new subscriber needs double opt-in confirmation.

In Open Flow, replace the host in **Subscribe to list** and **Create and send campaign**. Create two secret Variables containing URL-encoded form bodies, then bind each variable to the corresponding node’s **Body** input. Use the same list ID in both bodies. Encode every value as form data, including the API key and HTML:

*   Subscription body: `api_key=KEY&name=NAME&email=EMAIL&list=LIST_ID&boolean=true`.
*   Campaign body: `api_key=KEY&from_name=NAME&from_email=EMAIL&reply_to=EMAIL&title=TITLE&subject=SUBJECT&html_text=HTML&list_ids=LIST_ID&send_campaign=1&boolean=true`.

The examples show field names, not ready-to-send values. Encode special characters in each value before joining the fields, keep both bodies secret, and use an endpoint that does not redirect. In n8n, configure **Subscribe to list** with a Custom Auth credential containing JSON with `headers` set to `{ "Content-Type": "application/x-www-form-urlencoded" }` and `body` containing `api_key`, `name`, `email`, `list`, and `boolean` set to `"true"`. For example, the credential JSON is:

```json
{ "headers": { "Content-Type": "application/x-www-form-urlencoded" }, "body": { "api_key": "YOUR_KEY", "name": "YOUR_NAME", "email": "YOUR_EMAIL", "list": "YOUR_LIST_ID", "boolean": "true" } }
```

Configure the Sendy credential and sender, campaign and list fields in **Sendy1**. Use the same list in both nodes.

## Behavior

A successful subscription request is followed by campaign creation with immediate sending enabled. Sendy may return that the campaign was created or is now sending; this is not proof of delivery. Failure stops later steps. No automatic retry or rollback is configured. A lost response may mean the subscription or campaign succeeded, so inspect Sendy before retrying.

## Changes to the source

*   Replace the original personal details and list with configuration. Open Flow sends the documented form requests using secret body Variables; n8n uses Custom Auth for subscription and its native Sendy credential for the campaign, accepting subscription success responses `true` and `1`.
