“Customer.io can do what other marketing automation tools can’t—take in millions of events from users per day, segment through them almost instantly, and use any campaign action imaginable to create workflows.”

“Onboarding our last few brands took days, not the weeks the first one took. Every workflow we built for Nissan was already there for Volvo. That's not integration, that's compounding.”

“GoChat talks to the customer. Customer.io is the brain. Every decision—who to follow up, when, with what message, which salesperson takes it, when to escalate—lives in Customer.io. That separation is what let us scale without rebuilding.”

“We were selling tens of thousands of vehicles a year and had no idea what happened between a WhatsApp lead and a signed contract. The funnel existed, we just couldn't see it. Today we follow every lead from the first message to the SAP invoice, across all ten brands, in one place.”

“We chose Customer.io because we knew we'd eventually want to do things like this. We're just getting to the point where we can actually build them.”

“The visual workflow builder was key for managing something this complex. When you have 35 variants across multiple languages, being able to see the whole flow on a single canvas is what keeps it from becoming chaos.”

“We realized that giving guests more control over what they received didn't mean we'd hear from them less. It meant the people who stayed on the list were actually engaged. That was the foundation we needed to build everything else on.”

“The cool thing is, we were able to do this in about three days. Before Customer.io, putting something like this together would take two weeks. We are able to send out personalized content for our customers 4x faster than before.”

“A/B testing now is very fast for us. We have been able to conduct 7x more tests than we did last year, increasing our overall conversion by 2.7 times within the first 4 months of using Customer.io. This makes our executive team very happy. Everyone’s happy. Having tangible numbers to justify why we went with a specific message or campaign flow is really valuable to me.”

“Now we have all of the data and tools we need, which enables us to quickly build [gift notification emails] in the campaign builder with no additional engineering support required.”

“The sales results are real. Goodlight AI and Customer.io are one of the best business decisions we made in 2025.”

“We needed to send millions of hyper-personalized emails every month, but no other ESP was able to effectively handle a situation where every one of those emails was different. Customer.io was the best choice for us to enable deeper personalization than any other service. Combined with their excellent solutions support, they have become our preferred partner at Goodlight AI.”

“We haven't met a single large retailer in Mexico that is actually capable of having this information right on their screen for the marketing person doing the campaigns, without requiring any participation from the data team.”

“Customer.io was super easy to start with, and also super robust to scale. Some platforms are either super robust but difficult to start, or they're very simple but you can't do complex things. We needed flexibility to get data in and out easily, and the capability to handle sophisticated use cases.”
