[Coolify](https://coolify.io) is an open-source, self-hostable alternative to Heroku and Netlify. You can easily integrate Reloop into your Coolify applications or use Reloop SMTP as the global system transactional mail provider.

   - **SMTP Server**: `smtp.reloop.sh`
   - **SMTP Port**: `587`
   - **SMTP User**: `reloop`
   - **SMTP Password**: `rl_your_api_key`
   - **From Address**: `noreply@yourdomain.com`
4. Click **Save**.
