The software is easy to use, has an intuitive interface and offers many options for tracking your file's progress and status. It also allows you to set alerts when certain events occur so that you can be notified if there are any issues with delivery or receipt (such as unread receipts). I like how it lets me know exactly where my file is at all times via email notifications. This way, no matter what time zone I am in, I always have access to information about my file. Sometimes, depending on internet connection speed, it takes awhile for emails sent through this program to arrive. If they do not arrive within a few minutes after being sent, then I would recommend contacting customer service immediately because it could mean that something went wrong during transmission.
