You can run the same build on multiple computers, getting a new notification whenever a new device gets connected. Notifications will come directly to your chosen email address.
You can receive reports at whatever interval set, starting from 1 minute. Note that setting a too low interval means that you will get your email address flooded by reports.
Make sure you're either using a crypter or adding the keylogger to your AV exceptions when running it, otherwise your system will detect it and take it down.
