An easy way to get started with API and SMTP capabilities with SocketLabs.

When you first create an account with SocketLabs, you will be presented with the option to use the sandbox.  A "sandbox" is an isolated environment that allows you to experiment with your configurations without sending out any messages to your contacts.

Sandbox Rules

The sandbox only sends as the sandbox domain,, and can only send to:

- The email address used during sign up

- Our API and SMTP test email addresses

These restrictions apply to our SMTP, Injection API, and our Marketing Tools. 

Sandbox Removal

Your sandbox will be removed when you have added a domain and completed email address verification, Custom Bounce, DKIM, or Engagement Tracking.
