# Yandex Cloud Postbox overview

Yandex Cloud Postbox is an email service that provides a simple and cost-effective way to send emails from user [addresses](glossary.md#adress) and allows you to flexibly set up delivery [notifications](notification.md).

Yandex Cloud Postbox is optimized for sending transactional emails, notifications, informational and marketing newsletters, and other types of correspondence. You may choose to unsubscribe from newsletters and forward emails that got answered by users.

You can develop your own software solutions, e.g., generate customer support tickets from incoming emails or build [integrations](#integration) with cloud systems and your own information systems.
