Using something else?

MailSetu is a standard HTTP API. If your language or framework isn't listed, use any HTTP client to call the REST API directly — it's just a POST request with a JSON body and an API key header.

See the cURL guide 
curl -X POST https://api.mailssetu.in/v1/emails \
  -H "Authorization: Bearer ms_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "from": "you@yourdomain.com",
    "to": ["user@example.com"],
    "subject": "Hello from MailSetu!",
    "html": "<p>Your first email.</p>"
  }'
