# Configure Email Address

Let's set up the sender email address which sends the alert email when the counter exceeds its threshold limit. You can learn about Mail, a [Catalyst Cloud Scale](https://docs.catalyst.zoho.com/en/cloud-scale/getting-started/introduction/) component in detail from the [Mail help page](https://docs.catalyst.zoho.com/en/cloud-scale/help/mail/introduction).

To add a new email address in Catalyst:

1. Navigate to the *Cloud Scale* section of ther console, and click **Start Exploring**.

Once you add an email address, you must verify it before you can use it. The *Confirmation Status* column displays the verification status for the email address.

To confirm the email address, click **Click to confirm**. This will automatically send an email to the email address containing a confirmation code.
