How to send emails from your Instance

Reviewed on July 21, 2025

By default, remote SMTP ports (25, 465, and 587) are blocked and cannot be accessed from our infrastructure to prevent spam. To send emails from your Instance, you need to open these ports in the security group configuration.

Before you start

To complete the actions presented below, you must have:

• A Scaleway account logged into the console
• Owner status or IAM permissions allowing you to perform actions in the intended Organization
• At least one Instance
• Completed the identity verification process (KYC)

1. Click CPU & GPU Instances on the side menu of the Scaleway console.

2. Click the Security groups tab.

3. Select the security group for which you want to enable SMTP ports.

   Note

   If you have not created any security groups, your Instance has been assigned to the default security group, so this will be the one you should modify.

4. Tick the checkbox Enable SMTP.
