Email is sent via **Mailcow SMTP** (`***REDACTED_SMTP_HOST***:587` STARTTLS). After importing workflows, create an SMTP credential in n8n named "Mailcow SMTP" with the host/user/pass above.
To set keys, create `/opt/websites/cosmolocal-website/.env` on the server and redeploy.
All credentials are stored in `.env` on the server (gitignored). See server admin for values.
