      Sailing Smoothly with Customer.io

      I hold an extremely positive view of Customer.io. I find the UI/UX to be very smooth and clean, and the customer service is exceptional. Having used many ESPs, it's vital for me to operate without interruptions. In my experience, Customer.io stands out for its UI/UX among competitors. Our account representative is always available for assistance and consultations, which adds value to our relationship. Although I wish there was a ready-made solution for opt-in forms, it integrates well with our third-party app, so it's not a significant issue. Any shortcomings are more than made up for by the quality of their platform and their integrations. I switched to Customer.io because it fulfills all our needs, integrates better with our tech stack, and provides a much better user experience.

      Customer.io: An Invaluable Tool for Marketing Professionals

      As a marketing professional, I find Customer.io to be an invaluable tool for my daily operations

      Fantastic Marketing Tool!

      I think the software is excellent and meets all our requirements. The highlight is the automations, which let us effortlessly create and manage any campaign. However, it would be helpful if we could duplicate a whole workspace with all segments and campaigns, rather than rebuilding everything. Another beneficial feature would be a dynamic wait or an integrated queue system for webhooks. We selected Customer.io because it automatically filled in customer attributes when we connected Segment and it also had superior logic control.

      Highly Dissatisfied with Customer.io

      My experience with Customer.io has been incredibly frustrating. We've used their platform for push notifications, but the results have been disappointing. The delivery rate of notifications is only 1-2%, which is unacceptable for a service that promises effective communication. The notifications are often delayed, sometimes up to 45 minutes, which hampers our engagement with customers. The support we've received has been unsatisfactory. Despite our attempts to get help, Customer.io's support team hasn't been able to fix these issues. We've been left to deal with a faulty service on our own. Furthermore, Customer.io's management hasn't offered any compensation or discount for the problems we've faced. It's disheartening to see a company not taking responsibility for their promises and failing to acknowledge their shortcomings. Our integration costs with Customer.io were also very high. We invested a lot of time and resources into this platform, only to face numerous problems and unsatisfactory results. If I could go back in time, I would definitely choose a different service provider. Customer.io has left us deeply dissatisfied with both their product and their customer support. I hope that by sharing our experience, others can avoid the same frustrations we've endured.
