# Notifications ## Notification templates Notification templates are text files with HTML content and WorkflowGen macros. The default notification templates are located in the `\wfgen\App_Data\Templates\Emails` folder.
The stylesheet must be embedded in the template. You can attach a file to the notification via the `` macro. #### 📌 Example of notification template HTML code (body section) ```markup ...
Subject: A new action that you can handle has been created.
Action:
Description:
Link: View action
Associated data:
 
... ``` You can also use a custom notification template in a process data and use this process data in an additional notification of a workflow action.
For more information, see the [Custom Notification Templates](https://docs.advantys.com/workflowgen-administration-module-reference-guide/custom-notification-templates) section in the [WorkflowGen Administration Guide](https://docs.advantys.com/workflowgen-administration-module-reference-guide/). ## SMTP gateway We recommend using the local IIS SMTP server. There are several advantages to using an SMTP relay at the IIS WorkflowGen server: * Better performance, since messages are sent directly to the relay. * Local SMTP acts as a buffer to avoid loss of emails if the main SMTP server is not available. * Connection problems are reduced because the relay manages communication problems. * The relay traces email deliveries in its own log files. * The relay allows you to limit access to WorkflowGen. * The relay supports SMTP authentication and encryption (TLS encryption) to connect to your Exchange SMTP (or other mail server). WorkflowGen supports pickup directories for best performance and availability. This means that the notifications are created in a pickup directory managed by the SMTP server. IIS SMTP server and Exchange support pickup directory management.
