I've been absolutely blown away by the capabilities of Customer.io - the way that it integrates with our other systems, the range of communication methods and the degree to which they can be tweaked, customised and optimised is incredible. Performance has been great - I've encountered literally 0 bugs or unexpected behaviours so far. The truly impressive part to the whole thing is how user friendly the system is - managing complex workflows is a breeze, even for the less technical amongst our team. The platform's pricing structure is fair and justified given how powerful it is and how enormous the potential to generate ROI from it is. I dealt with their customer service team during our onboarding process and they handled my enquiries promptly and effectively. Review collected by and hosted on G2.com. What do you dislike about Customer.io? I haven't really encountered anything I would say that I really "dislike" about Customer.io - of course there are challenges around understanding its range of capabilities, navigating the set up and running of campaigns etc, but that's quite understandable. I will never go back to traditional platforms that only broadcast to subscriber lists ever again. Review collected by and hosted on G2.com.
