# Send new credit notifications using Koin default email

Koin can automatically send a notification email to your customers whenever a store credit is issued. Once set up, the email is sent immediately after the credit transaction is created successfully.

Here’s what the email looks like:

### How to set up:

* Go to your **Koin Dashboard > Programs**.
* Select your **Cashback** or **Custom** program.
* Find the **Email Notifications** section.
* Edit the **Email Subject** and **Email Body** fields.

There are fixed fields that can not changed:
* The Shop Now button
* The overall template (color, font..) of the email. 

### Notes
* If you want more flexibility in designing your emails, you can use **other tools** such as **Klaviyo** or **Shopify Email**. Learn more at [Send new credit notifications using Shopify email system](https://support.getkoin.io/en/article/send-new-credit-notifications-using-shopify-email-system-s3rcky/) and [Send credit notification email with Klaviyo](https://support.getkoin.io/en/article/send-credit-notification-email-with-klaviyo-xec0tg/).
* When using an external tool, kindly **disable** the Email Notification setting in Koin to avoid sending duplicate emails.
* Customers who have unsubscribed from your marketing emails might still receive this notification, as it’s sent through a different email service. They will need to unsubscribe directly from this type of email if they no longer wish to receive credit notifications.
