When using an Exporter to trigger an Email/SMS template to be sent, it is important to set a filter so that only one is sent. This is necessary since the Exporter will trigger each time a transponder is read for the given Timing Point. This article will explain how to avoid this.

We first want to create an additional field as a checkbox called EmailSent. We will use this field to track whether the email was sent or not.

In your Email/SMS template, there is a setting under More Options called "Set checkbox Field". Here you can select the EmailSent field you created. Once the email is sent (manually or using the Exporter), this checkbox will get set to checked.

In your Exporter settings, add the filter below. This will check to see if the EmailSent checkbox is checked. If it is not checked, the email will be sent. If it is checked, the email will NOT be sent.

[EmailSent]=0
