{% endstep %}

{% step %}
Open the sandbox (named **My Sandbox**) created by default.

{% endstep %}

{% step %}
Under the **Integration** tab, select **SMTP** and copy the credentials such as Host, Port, Username, and Password.

{% endstep %}

{% step %}
Paste them into your email-sending script, service, or MTA (any service that supports SMTP integration), and run it. The email will arrive in your sandbox in a few seconds.

{% endstep %}
{% endstepper %}

## Select your integration

Instead of copy-pasting the SMTP credentials, you can use the code samples already containing your credentials.

{% stepper %}
{% step %}
In the **Integration** tab of your sandbox, scroll down to **Code Samples** and select the programming language or framework you're working with.

<div align="left" data-with-frame="true"><img src="/files/A3dfITyAqLo7AHFJA1JT" alt="Code Samples section showing various programming language options for integration" width="563"></div>
{% endstep %}

{% step %}
Copy the configuration and paste it into your email-sending script. Then, run it. The email will arrive in the sandbox in a few seconds.
{% endstep %}
{% endstepper %}
