Use case: Checking the content of backup emails
Use PRTG’s email monitoring capabilities to constantly check the status of your backups and other processes.
As most backup software, for example Veeam, sends emails to indicate whether or not a backup was successful, and many other applications send important messages by email as well, monitoring the content of these emails is the easiest way to keep an eye on such processes.
If an email notifies you of a serious issue, you can configure PRTG in a way that it immediately alerts you via SMS or push notification – no more sifting through a pile of emails on the next workday when it may already be too late.
Email monitoring & mail server sensors included with PRTG
IMAP
The IMAP sensor monitors the response time of a mail server and the number of emails in the defined mailbox. The sensor also comes with special filters and assigns statuses based on words or phrases found in emails. For example, PRTG can scan the subject or body of an email for keywords defined by you.
SMTP & IMAP Round Trip
The SMTP&IMAP Round Trip sensor uses SMTP and IMAP to monitor the end-to-end delivery of your email, more specifically, the time it takes for an email to reach an IMAP mailbox.
SMTP & POP3 Round Trip
The SMTP&POP3 Round Trip sensor uses SMTP and POP3 to monitor the end-to-end delivery of your email, more specifically, the time it takes for an email to reach a POP3 mailbox.

Monitoring emails: FAQ
What is email monitoring?
Email monitoring involves the systematic tracking and analysis of email communications within an organization. It typically includes connecting to email accounts and scanning email content, attachments, and metadata for various purposes such as security, compliance, and performance evaluation.
What is mail server monitoring?
Mail server monitoring is the process of continuously observing the performance, availability, and security of a mail server infrastructure. This includes tracking server uptime, response times, mail delivery rates, and disk space usage.
Email and mail server monitoring tools often generate alerts for potential issues such as server downtime or high email queue lengths, help ensure smooth email operations, minimize downtime, and enhance overall email service reliability and security.
Why should I use email monitoring software?
Email monitoring software offers several benefits for organizations, including:
- It helps detect and prevent security threats such as phishing attacks, malware distribution, and unauthorized access to sensitive information.
- By analyzing email usage patterns and identifying inefficiencies, it can optimize email workflows.
- It tracks email server performance metrics, making sure that emails are delivered correctly and in time.
How does PRTG ensure emails are delivered?
To make sure that emails are delivered correctly, PRTG comes with preconfigured email round trip sensors. These sensors check the following process:
- Step 1: PRTG delivers an email to the mail server or an email client (for example, providers such as Windows Outlook, Gmail, GMX, and others) via SMTP.
- Step 2: The SMTP server delivers the email to a POP3 server (which can be at another location, in the LAN, or on the same server).
- Step 3: PRTG checks for emails from the POP3 server every second until the test email arrives.
How do I use PRTG email monitoring for applications and backups?
- Step 1: In PRTG, add the IMAP sensor to the device that represents your mail server. Make sure the application to be monitored is able to send status emails to the corresponding email address.
- Step 2: Specify the conditions for which you would like to be alerted, for example, if you have not received an email for 24 hours from your backup software, or if certain words such as “error” appear in an email.
- Step 3: Test your configuration by sending yourself an email with the words that you specified in your filter rules.
How will I be notified if my mail server is down?
PRTG offers multiple methods to send out alerts, including SMS, Teams and Slack message, or in-app push notification. This ensures that users can be informed in multiple ways, even if there is an issue with the mail server itself and email delivery is not possible.
What is a sensor in PRTG?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.
On average, you need about 5-10 sensors per device or one sensor per switch port.
