Nosto

It has been a nice app to have. I have been using it for over 6 months now.

Pop up coupons have worked well for my store giving good returns.

Would like more ease, versatility & flexibility in creating facebook & instagram ads. Did try the facebook ads a couple of times but there were no sales from them.

Emails have not brought any sales either. They should make the email templates more engaging and better.

We've had Nosto for a few months now and it has helped us to achieve things that otherwise wouldn't be possible - like cart overlay recommendations and product bundles. We've had a very helpful integration manager.

Good app - definitely contributes to increased sales. Found some of the analytics hard to find in the dashboard (under 'settings'). Also a bit of work to cut the data to get the exact info we want from it.
Support team are incredibly responsive and really help to push performance.
All in all a very good solution to cross-selling - v. minimal management, just let it run.
