# Overview

Send PayPal invoice emails from your own email domain instead of [service@paypal.com](mailto:service@paypal.com). Set up your custom email in your [PayPal dashboard](https://www.paypal.com/invoice/s/settings/custom-domain?utm_medium=paypal_dev_docs) without the need for API integration.

Your custom email applies only to buyer-facing invoice emails, including invoice notifications, reminders, updates, and cancellations. Payment receipts and merchant notifications continue to use the default PayPal sender, [service@paypal.com](mailto:service@paypal.com). If your custom email becomes unavailable, PayPal automatically falls back to this default sender to ensure uninterrupted email delivery.

## How it works

* Setup: You add DNS records to your DNS provider to authenticate your email.
* Verification: PayPal verifies your domain ownership.
* Email sending: Buyer-facing invoice emails are sent from your domain instead of [service@paypal.com](mailto:service@paypal.com).
* Automatic fallback: If your domain becomes unavailable, PayPal automatically sends invoice emails from [service@paypal.com](mailto:service@paypal.com) to ensure uninterrupted delivery.
