# Catalyst Mail

> **Note:** This SDK is currently in deprecation. Migrate to [JavaScript SDK](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/cloudscale/mail/get-mail-instance/) now.

[Catalyst Mail](https://docs.catalyst.zoho.com/en/cloud-scale/help/mail/introduction) enables you to add the email
addresses of your business that will be used to send emails to the end-users from your Catalyst application. You can
configure email addresses of public domains or of your organization's own domains. You can also use an external email
client of your choice and configure its SMTP settings with Catalyst, instead of using the built-in Catalyst email
client.

#### Get Component Instance

You can create an `email` reference as shown below. This will not fire a server-side call. We will
refer to this component instance while performing the send mail operation.

```javascript
//Create an email instance 
let email = app.email();
```
