<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Notification Delivery
On the Notification Delivery tab, you can define and test global settings for notification delivery. If you do not want to use a specific notification method, leave the respective fields empty.
This documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.
If 15 minutes (900) seconds have passed since your last credential-based login and you open a setup page from a different setup page, PRTG asks you to enter your credentials again for security reasons. A dialog box appears. Enter your Login Name and Password and click OK to continue.

Note
You must take the following four steps to set up and use notifications:
- Check and set up the notification delivery settings if you use PRTG Network Monitor. These settings define how PRTG sends messages.
- Check and set up notification contacts for the user accounts. These contacts define the recipients to which PRTG sends notifications.
- Check and set up several notification templates. These templates define the notification methods and their content.
You can also check or edit notification templates via the Notification Triggers tab. For more information, see section Notification Triggers Settings.
- Check and set up notification triggers settings for objects. These triggers define when PRTG sends notifications.
Usually, there are three successive attempts to deliver a notification. If all of these attempts fail, the notification is lost. To never miss a notification, we recommend that you always set up at least two notifications with different notification methods for a notification trigger, for example, one email notification and one SMS notification. If delivery via email fails, PRTG can still notify you via smartphone as a fallback. For example, use the latency setting of a state trigger to choose a notification with a different notification method than in the first trigger condition, or set up a second trigger with a different notification method for the corresponding object.
For a detailed step-by-step guide, see the Paessler website: How to set up notifications via the PRTG web interface.
Custom notification scripts are also available in the PRTG Sensor Hub.

SMTP Delivery

|
Delivery Mechanism
|
Define how PRTG sends emails via the Simple Mail Transfer Protocol (SMTP):
- Use direct delivery with the built-in email server (default): Use the built-in SMTP relay server. This server manages its own email queue. For each email, it looks up the target SMTP server via the MX record of the target domain, and sends the email.
- Use one SMTP relay server (recommended in LANs/NATs): Set up your own SMTP relay server to send emails. Enter data below.
- Use two SMTP relay servers (primary and fallback server): Set up two SMTP relay servers with one as the primary relay server and one as the fallback relay server. Enter data below.
If you monitor the IT infrastructure in your network address translation (NAT) or LAN, use your own LAN-based relay server to ensure faster delivery of notification emails.
This option is not available in PRTG Hosted Monitor. PRTG Hosted Monitor uses sendgrid for email notifications. For more information, see the Paessler website: FAQ – PRTG Hosted Monitor.
|
Sender Email Address
|
Enter an email address to use as the sender of all email notifications. This setting is global and applies to all email notifications by default.
You can override the sender email in the settings of individual notification templates.
|
Sender Name
|
Enter a name to use as the sender of all email notifications. This setting is global and applies to all email notifications by default.
You can override the sender name in the settings of individual notification templates.
If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?
|
HELO Ident
|
Enter a server name for the HELO part of the mail protocol.
For some mail servers, the HELO identifier must be the valid principal host domain name for the client host. For more information, see SMTP RFC 2821.
The HELO identifier must be a unique name.
Only ASCII characters are allowed.
We recommend that you use the Domain Name System (DNS) name of the PRTG core server system.
This option is not available in PRTG Hosted Monitor.

SMS Delivery
Although PRTG has built-in support for the application programming interface (API) of some SMS providers, we cannot officially provide support for them. If you have technical questions about SMS delivery beyond PRTG, contact your SMS provider directly.
Instead of using a preconfigured provider, you can use a custom URL that enables you to use extended parameters. This is also an alternative to using providers for which we offer preconfigured options.
You need an internet connection to send text messages via the HTTP API.
For information about sending SMS via separate hardware using third-party software, see the Knowledge Base: How can I send SMS text message notifications via a modem or a mobile phone with PRTG?
