The most impressive thing about this product for me was how easy it made using multiple email addresses to communicate in one account, instead of having separate accounts like I had been doing before! It's also great because you can block certain people from communicating through your system so they cannot send things directly into their own inboxes or contact other clients/customers if not approved by an admin first (like myself). Not much at all; sometimes there are difficulties while trying new features out but nothing majorly frustrating either way- just keep going until everything works smoothly then stick around afterwords :) Sometimes we do get emails sent straight back our main personal address which could be potentially harmful depending where its coming form as well since some states don't allow spamming messages etc., however these instances have never turned up something damaging yet :D We've always managed any possible issues quickly once notified though usually within 1 day - 2 tops! Very useful platform considering everyone has different needs /.
