Safeguard email security & personal privacy

Email is a core part of everyday life, and no matter whether you are at work, school, at home, or traveling, you send emails through different IP addresses. In some areas, you may even require special software to use Gmail. In these circumstances, reading emails becomes inconvenient, and the IP addresses you use will be recorded and may cause a potential threat to your privacy. Realizing the need for high security and privacy, QNAP offers “QmailAgent” - an online email agent for QNAP NAS. Sending emails with QmailAgent can prevent IP addresses being recorded or blocked. Coupled with SSL transmission and the support for multiple email accounts, QmailAgent provides a wonderful tool to safeguard your email security and personal privacy.

Push Notifications

QmailAgent supports push notifications, allowing you to receive real-time notifications on QTS Desktop and Chrome™, Safari® and Firefox® browsers without opening the application.

Note: QmailAgent 1.2 (or later) is required to use push notifications.


QmailAgent is an online email client that helps you manage multiple email accounts, allowing you to access all of your emails and to easily switch between different accounts. It provides complete functionality for composing, reading and organizing emails. You can even attach files, photos and documents from the QNAP NAS when composing emails.

Back up emails to your high-capacity NAS

After importing email accounts, QmailAgent will automatically back up all your emails to your QNAP NAS. You do not need to worry about unexpected email data loss and accidental deletion anymore. All the email backups are listed in the folder by date, and are well organized for you to easily search through them.

Switch accounts in one click

QmailAgent supports multiple major email services and those using IMAP. Whether you have Gmail™, Yahoo®, Outlook®, or any IMAP-based email accounts, you can quickly switch between them to browse, reply, forward emails, and attach and view files in the mails.

Read your emails conveniently

In the past, you needed to download emails from the NAS to a local computer to read or send emails. Now, you can not only browse emails stored on the QNAP NAS with QmailAgent, but also open those email backups directly from the folders in File Explorer.

Instant search. Better searches.

When dealing with countless emails spread across multiple email accounts, it may be hard to find important messages. With QmailAgent’s search criteria, you have a wide range of search criteria including sender, receiver, subject, subfolders, and more.

Attach NAS files to emails and share with SmartShare

QmailAgent allows you to attach files, documents or multimedia files stored on the NAS to emails. When inserting large files, QmailAgent will automatically create a “SmartShare” link in the email - allowing you to send attachments without exceeding any file size limits. With myQNAPcloud/CloudLink functions activated, it helps guarantee that recipients can receive emails and directly click links to preview and download attachments.

Qsirch empowers searching through email backups

QNAP’s exclusive full-text search tool “Qsirch” also includes a powerful email search function. You can customize search criteria (such as date, attachment, sender, recipient, etc) to search through .eml files and find emails stored on the QNAP NAS with greater efficiency. Using QmailAgent together with Qsirch can make managing and searching through massive quantities of emails much easier.
