# Understand customer emails
> Learn which customer emails Smile sends and when they're triggered.
Smile automatically sends customer emails for key loyalty program events. This article explains when each email is sent and the variables you can use to customize it.
Manage customer emails from **Settings** > [**Customer Emails**](https://app.smile.io/settings/customer-notifications), where you can enable, disable, and customize the content of each email.
For a complete list of variables you can use in the **Subject**, **Title**, and **Description** fields, see [**Use variables in customer emails**](/en/articles/4036262-use-variables-to-insert-relevant-information-into-customer-emails).
## **Available customer emails**
Smile can automatically send the following customer emails:
* Points earned
* Reward redeemed
* Birthday reward
* Points expiry
* Reward expiry
* Referral shared through Smile
* Friend received referral
* Referral completed
* VIP tier achieved
The sections below explain when each email is sent and which variables you can use to customize it.
## **Points earned**
**Sent when:**
A customer earns points by completing an eligible earning action, such as making a purchase.
**Note:** Smile does not send **Points earned** emails when customers:
* earn points through any social media earning rule
* earn points from the **Sign up** earning rule
This helps reduce the number of emails customers receive when creating an account.
If you'd like customers to know they've earned sign up points, consider updating your eCommerce platform's account confirmation email to include this information.

## View customer email activity
Smile Admin doesn't display send or delivery information for individual customer emails.
