The ability for us to have an easy way to target our customers with what they are interested in, this makes it easier than ever before! I love being able to see exactly where my customer's interests lie so we can direct them towards products or services tailored to those specific needs.
Not much at all really because there isn't anything i dislike about fixel but if you're looking into something like this then give it go as its definitely worth trying out! Targeting people who want solutions from me without having any interaction required was always quite hard work but now thanks to fixels new product called 'fixel chat' things has changed drastically!
