You can configure the email address as follows: To configure an appropriate sender email address: 1. Navigate to the **Mail** component present under the *Notify* section in the *Cloud Scale* section of the console. ![catalyst_tutorials_signals_event_app_mail_start_look](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_mail_start_look.webp) 2. Enter the *Display Name* as **Onboarding**, and enter the email address you are going to use to send out emails to your end-users. Click **Add Email**. ![catalyst_tutorials_signals_event_app_enter_email](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_enter_email.webp) The email address will be added. ![catalyst_tutorials_signals_event_app_mail_added](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_mail_added.webp) But, to use it and to ensure that the email address used is secure and valid, you will need to verify it. 3. Click the **Click to confirm** button, and enter the code sent to the entered email address. ![catalyst_tutorials_signals_event_app_mail_confirmed](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_mail_confirmed.webp) The email address will be confirmed. ![catalyst_tutorials_signals_event_app_mail_first_action](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_mail_first_action.webp) Next step is to verify the domain. 4. Click the **Domain** tab, and click **Add Domain**. ![catalyst_tutorials_signals_event_app_mail_domain_start](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_mail_domain_start.webp) > **Note:** If you are using a public email service provider such as **Gmail** or **Outlook** for your sender address, you can skip this process. Domain validation is required only when you use a sender email hosted on a private or custom domain. For more details, refer to the [Help documentation](https://docs.catalyst.zoho.com/en/cloud-scale/help/mail/domains/). 5. Re-enter the email address you are going to be using to send out emails and click **Create**. ![catalyst_tutorials_signals_event_app_mail_renter_domain](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_mail_renter_domain.webp) Since the email address has already been confirmed, it will be automatically verified. ![catalyst_tutorials_signals_event_app_mail_domain_verified](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_mail_domain_verified.webp) With the email address confirmed and the domain verified, the Mail component has been successfully configured for this application. ![catalyst_tutorials_signals_event_app_mail_completed](https://catalyst-docs-development.zohostratus.in/images/tutorials/event-app/catalyst_tutorials_signals_event_app_mail_completed.webp) This email can now be used to send out the required mails to the end-users of your application. > **Note:** You can learn more about the **Mail** component from this [help documentation](https://docs.catalyst.zoho.com/en/cloud-scale/help/mail/introduction/).
