I like that it is easy to use, very effective in blocking spam emails as well reducing my bounce rate so i receive more email deliverables from customers or potential clients! It also helps me block phishers who are trying scam people by impersonating someone they know which includes myself with an old password of mine being used for another person.
The only thing we dislike about this tool was its price but because our organization has been using their services since 2013-2014 there should have always be some discount given during these years. We've seen significant increase when managing customer inboxes regarding delivering newsletters etcetera without having any problems due to Spam filters at all times compared before installing brandsecure software within one year ago now.
