I have used this product for many years in my business and with the help of the support team, they are extremely helpful and kind to work with. They are very thorough and they do not skip anything. I highly recommend them. I don't have many complaints. I can think of nothing that I would dislike about their customer service and products. They have been extremely helpful through all of our campaigns. The only thing they haven't done yet is add an option where we could export our list directly to MailChimp. This is such a simple addition that it should be a no-brainer for them to add. It's so important to us that we keep our contacts up to date with what is going on in our business.
