      Superb Marketing Automation Tool with Exceptional Support Team

      I mainly use Customer.io for lead nurturing and I'm confident they'll improve their product with better reporting features. I've tested many marketing automation tools and Customer.io stands out for its user experience, documentation, and customer support. It can be complex depending on your needs, but their excellent user experience, documentation, and support team provide solutions. There are some missing features like cohort analysis, but I'm hopeful they're working on it. I switched to Customer.io because I needed a tool with genuine Marketing Automation Platform features.

      Unexpected Data Sharing: My Experience with Customer.io

      As a valued customer of Celsius Network, I had an interesting journey with Customer.io. They showcased a unique approach to managing contacts, which led to a situation where an employee utilized my data and shared it with an unexpected third party. This was a surprising twist that added a layer of intrigue to my experience!

      Fraud Alert. Avoid Customer-io.

      I believe that customer-io is a scam. They charged us for inactive users and even users without emails! Despite removing them from our code base, they continued to create new profiles and charged us for it.

      Mastering Email Automation with Customer.io

      I find customer-io not very user-friendly, but it's one of the best for email automation. I like running my drip campaigns on it and managing their complexity. However, it needs a dedicated developer, which isn't always possible. I think there should be some automated codes.

      Slow Email Support, Debugging Challenge with Customer.io!

      In my updated review, I acknowledge that the email support of Customer.io is helpful, although I still believe there are many standard features missing compared to other email tools. In my original review, I criticized their customer support for only being available via email and taking over 24 hours to respond. I suggested they should offer live chat or limited use of Zoom or calls. I stressed that if they only provide email support, responses should be within hours, not a day or more.

      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.
