# Customize email sender name and reply-to address

> Configure the sender name your customers see and the email address that receives their replies.

Customize your email sender name and reply-to email address to keep your loyalty emails clear and on-brand. The sender name appears alongside your emails in your customers' inboxes, and the reply-to email address determines where customer replies are sent. You can update both settings at any time on any Smile plan.

<Note>
  **Note:** Customer emails are sent from [**rewards@customer-mail.smile.io**](mailto:rewards@customer-mail.smile.io). This address can't be changed because it's used for email authentication and reliable delivery.
</Note>

2. In the **Customer Notifications** card, update the **Sender Name** and **Reply-to-email** fields.
3. Click **Save**.

  **Note:** [yahoo.com](http://yahoo.com) and [aol.com](http://aol.com) email addresses can't be used as reply-to addresses.
