# EmailAlertChannel Construct

> Learn how to configure email alert channels with the Checkly CLI.

<Tip>
  For general information about alerting, see our docs on [email alerts](/integrations/alerts/email) and [alerting with Checkly](/communicate/alerts/overview/).
</Tip>

Use Email Alert Channels to send email notifications when checks fail or recover.

<CodeGroup>
  ```ts Basic Example theme={null}
  import { EmailAlertChannel } from "checkly/constructs"

  const emailChannel = new EmailAlertChannel("email-channel-1", {
    address: "alerts@acme.com",
  })
  ```

  ```ts Advanced Example theme={null}
  import { EmailAlertChannel } from "checkly/constructs"

  const emailChannel = new EmailAlertChannel("ops-email-channel", {
    address: "ops-team@acme.com",
    sendRecovery: true,
    sendFailure: true,
    sendDegraded: true,
    sslExpiry: true,
    sslExpiryThreshold: 30,
  })
  ```
</CodeGroup>

<Note>
  If you need to reference existing alert channels that were created outside of your CLI project, use [`fromId()`](/constructs/alert-channel#using-fromid-to-reference-an-existing-channel).
</Note>
