This is not bad. I love the product and it solves our customers needs. Sometimes, the results are difficult to understand. It would be nice if the reports of the data insights came along when you were creating them. There is nothing i dislike about this software. I'd say that it solved my problem for tracking each user by using a single ID number. That's it! No complaints at all. I like how easy it is to use this software when creating new accounts or adding customers into your database for future marketing campaigns! It's very simple but effective at getting results in my business which was one thing i didn't have before using yokozuma!! Nothing really there are any cons about their services because they do exactly what you need without much hassle with them. If u want an amazing tool then go ahead give these guys another try. ! You will be glad once again. !!
