I do not find them helpful for certain aspects - such as follow-up. We've found good success with this tool after creating an email campaign which was able to get our first qualified prospect to call us instead! The product itself worked great for me and it is an excellent product. The only thing I don't like about it is that you don’t have access to the phone numbers you are calling. This would be very helpful if that was possible, but the developers do a good job with that. We were going through the process of adding all our leads (over 30,000), but it is a bit of a daunting process to set up. I also had the issue of not being able to call all our leads right away, so I was constantly putting things off and had plenty of leads not being followed up on. We also had all the wrong information about the doctors that we were calling, so it was a lot of "what if” scenarios.
