# Send Message

| Step Details |
| --- |
| **Introduced in Version** | 3.0.0 |
| **Last Modified in Version** | 8.9.0 |
| **Location** | Integration > Amazon AWS > SES |

The **Send** **Message** step allows the user to send an email message through Amazon SES.

### Prerequisites

- This step requires the [Amazon AWS Module](https://documentation.decisions.com/docs/aws) to be [installed](https://documentation.decisions.com/docs/installing-modules-decisions) before it will be available in the toolbox, and an active [AWS account](https://signin.aws.amazon.com/signin?redirect_uri=https%3A%2F%2Fconsole.aws.amazon.com%2Fconsole%2Fhome%3FhashArgs%3D%2523%26isauthcode%3Dtrue%26nc2%3Dh_ct%26src%3Dheader-signin%26state%3DhashArgsFromTB_eu-north-1_c1412528899e4833&client_id=arn%3Aaws%3Asignin%3A%3A%3Aconsole%2Fcanvas&forceMobileApp=0&code_challenge=HQku5BPrRUboP5p1wGr4Ai_nBIQNSqsR2eHJNCBfxhQ&code_challenge_method=SHA-256). The [Amazon WebServices Settings](https://documentation.decisions.com/docs/setting-up-amazon-webservices-integration) must also be configured.
- A [dependency](https://documentation.decisions.com/docs/project-dependencies) must be created after installing the module in order for the the steps to be properly used.

## Common Errors

### Invalid URI

If the inputted value for the queue name under the Settings section is invalid, the step will cause an error.

To correct this, the parameters around the Message Queue are invalid and need to be reconfigured.
