Some Duet functionality requires a URL to be pinged periodically to work properly. For example, the
Recurring Invoicing functionality requires a URL to be pinged daily to send out the invoices and the
Reply to Discussion feature requires a URL to be pinged every few minutes to grab new messages and
add them into the appropriate discussions.
To set up this functionality, you will need to create a new email address that will only be used
for Duet only. This email address shouldn't be used for anything else because emails are deleted by Duet once
they are processed. A simple free Gmail account will work for this purpose
