When running an online store, communication with customers is key. By default, transactional emails like order confirmations and shipping updates are sent from a generic address. With Hostinger, you can connect your own domain to use as the sender address for your standalone store.
Using a branded sender address builds customer trust, improves email deliverability, and ensures your store maintains a professional appearance.
