# Official turboSMTP SDKs for C# and PHP Applications

> Find the official turboSMTP C# and PHP SDK source repositories, their requirements, and alternatives for sending email.

**Status: Official source repositories available.** The C# and PHP repositories contain API clients and examples. Follow each repository's setup instructions and check its release status before adopting a version.

For a direct HTTP integration, use the [Email API examples](/docs/sending/code-examples.md).

> [card] [C# SDK](https://github.com/turboSMTP/turboSMTP-csharp)
>
> C# source and examples. The SDK project currently targets .NET Framework 4.8.

> [card] [PHP SDK](https://github.com/turboSMTP/turboSMTP-php)

> PHP source and examples. Check runtime requirements and installation instructions in the repository.

## Prefer a framework integration?

If your framework already has a mail abstraction, use the native integration instead of an SDK:

* **Symfony**: [Symfony Mailer bridge status and SMTP alternative](/docs/integrations/symfony-mailer.md)
* **Node.js**: [Nodemailer service presets](/docs/integrations/nodemailer.md)
* **Elixir and Phoenix**: [Swoosh adapter](/docs/integrations/swoosh.md)

For any other language, see the [code examples](/docs/sending/code-examples.md) for cURL, Python, Node.js, PHP, Ruby, Go, Java, and C#.
