I have been using this for over 6 years, they are always accessible to help when needed most especially during business hours via phone or email support! It's great that you can set your own rules/categories so as long their not too many but it does get confusing at times with all of them if there aren't clearly labeled folders!! Great price point compared tot he competition out-of -pocket solutions in my industry; no real complaints here since its such an awesome product. I like that I can customize the filters I want to use and that I can use the service to help me forward emails from multiple addresses. I dislike that sometimes the service is slow and that I can't see who I am emailing from. I have been using this service for over 3 years now and haven't had any issues. It has been a huge help in keeping the inbox of my business email clean. I can see who I am emailing from and that helps me keep up with the different people I am emailing.
