n8n community node

Send Groundmail transactional email from n8n workflows with the community package n8n-nodes-groundmail.

This integrates Groundmail only (gm_ API keys, api.groundmail.dev). It is not the SuperSend cold-email product.

Install

In n8n: Settings → Community Nodes → Install → n8n-nodes-groundmail.

Self-hosted alternative:

npm install n8n-nodes-groundmail

Credentials

1. Create an API key in the Groundmail dashboard (gm_…).
2. In n8n, add Groundmail API credentials with that key.
3. Leave API Base URL as https://api.groundmail.dev unless you use a custom deployment.

Send an email

1. Add the Groundmail node.
2. Resource: Email → Operation: Send.
3. Set From (verified domain), To, Subject, and HTML and/or Text.
4. Optional: Reply-To, CC/BCC, idempotency key, schedule, template id, unsubscribe.

The node maps to POST /emails. See Send emails.
