ExactTarget has just announced it the availability of an application that enables marketers to monitor transactional emails, and make changes, in real-time.

Transactional emails are typically sent out to confirm purchases or let customers know when a shipment has gone out. Marketers have little to no control over the content of these automated messages.

The ExactTarget solution makes it possible to modify the content of such emails, as well as integrate information from external sources.

Emails continue to go out in a timely manner.

Beyond.com, which consists of over 15,000 online job sites and other destinations, has already deployed the solution.

Last month ExactTarget released a report about mobile users and email activity, seeking to trump many assumptions held by marketers about email perusal on a handheld device.
