What do you like best about Customer.io?

I think the best thing I like about the product is the ease of use and the thoughtfulness put into making everything work seamlessly. Not to talk of the fact that there's a lot of features and support.

Integration was seamless and their documentation was detailed.

Their support is also very much helpful. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

It would've been nice to have a customer support or live chat support.

Also, I think the web application documentation can be better. It was confusing at first. Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

Customer.io helps us send the right messages to the right users at the right time — automatically. As a small startup with limited engineering and marketing resources, this is incredibly valuable. We use it to onboard new users, re-engage inactive ones, and send personalized updates based on behavior. Without Customer.io, we’d struggle to create the kind of targeted communication that keeps users engaged and builds trust over time. It’s been a core part of how we retain users and create a better overall experience. Review collected by and hosted on G2.com.

What do you like best about Customer.io?

It has all of the fancy features that the new ESP's have for a fraction of the cost of the others. Segment based on events, properties, and all the properties nested within them. You can also build workflows that pull in all of that complex data. They just launched a new trigger utilizing a property within an event. We essentially stream all events from Segment without having to break the bank for our contract. They also have amazing customer support to help de-bug and look into issues. Absolutely floored in the best way by this ESP! Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

I wish they had more of a community like some of the other ESPs do. They did hold a conference, but it was virtual and I completely forgot about it because they didn't send me a gazillion email reminders like others do. I haven't met too many other CIO users but I'd love to nerd out with them if they facilitated a gathering! I've been in the email industry for 14+ years, and I haven't heard much about them until I started working at Monarch where CIO was already onboarded. Wish I would've known about them sooner. Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

This platform allows us to build sophisticated, personalized and triggered programs while keeping cost low. Review collected by and hosted on G2.com.

What do you like best about Customer.io?

All my colleagues says that it has been very easy to learn how to use the tool. It is very intuitive and building an email and sending it out goes very smoothly. The drag and drop editor was very stable to use for creating our company branded templates.

Also very much appreciate the support we have received from customer.io and that you have the ability to really improve the product by having your say when it comes to feature requests. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

I am lacking functionality in building segments and working with conditions in campaign workflows. I think there are small improvements there that could give great benefits, in order to make it easier to set up the email journey the way we like.

I also think the documentation could be improved with some more examples to make it easier to understand how you can use all the great features of customer.io Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

An easy to use marketing automation tool which can be used by several people in the organization. It should be easy to integrate with Google Cloud. So far this has been straight-forward to implement and get started with. Review collected by and hosted on G2.com.

What do you like best about Customer.io?

I really like the flexibility. We have around **350K** customers and a lot of campaigns **running**. The ability to spin up campaigns quickly has allowed us to move fast to address our needs. It's also incredibly powerful. The built-in features are great, but it's easy to connect to outside tools and scripting if needed. I **especially** like all the built-in A/B testing. The **administrative** visual reports allow me to quickly evaluate campaign/message effectiveness. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

I'd like to see some more powerful tools in the workflow builder. I'm not always able to branch in the ways that I'd like. Also, something as simple as assigning individual promo codes to a customer via messaging or a campaign often requires manual CSV importing or external scripting—I’d love to see a built-in feature for this. Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

Customer.io is automating our marketing efforts in a way that allows integrated testing, so we're always improving our flows & messaging. We're getting better and more personal with out customers. We're able to understand what works within a given customer cohort, double down and repeat. Review collected by and hosted on G2.com.

What do you like best about Customer.io?

Customer.io has been relatively easy for me to navigate and use on my own. I have experience with other platforms and not all are user friendly. Our account manager and the support team have also been extremely helpful along our jouney. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

Because our business is set up a bit differently than most there are some things that don't quite work for us. For example with the current set up, if I want to set the goal to be just having someone click an email I need to create a segment and set the goal to be for them to enter that segment. Another example is that some of our ongoing campaigns need to stop sending at a specific date, but currently we need to just make sure we go in on that day and manually stop them. Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

Customer.io has helped us greatly in segmentation, automation, reporting and deliverability. Review collected by and hosted on G2.com.

What do you like best about Customer.io?

We absolutely love the formatting features for email marketing! It is so easy to fully customize the appearance of our emails, add our branding, photos, etc, and not have to worry about distortion when our patients get the email! We also love that customer.io easily integrates with our Prompt, our EMR software. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

The software itself isn't "pretty" when you're creating an email and segmenting lists of patients to send an email to. It can be a bit overwhelming to understand all the options, but when you spend some time with it, everything makes sense! Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

Our current EMR platform does not have the ability for us to email patients whenever we want to. It only allows us to send drip marketing campaigns based on when a patient last had an appointment, or based on their injury. Customer.io is wonderfully filling that gap and allows us to send monthly newsletters to all of our active patients (all at the same time) as well as send out information about upcoming seminars, segmented out by which location the patient attends.

What do you like best about Customer.io?

Customer.io helps us to track every event, click, pageview happening in our platform automatically and create dynamic segments based on the activities of the people. And the best part, we can integrate it with our Backend so that we don't miss any events to adblockers. Normally this would take a dedicated person to track and analyze and act on those metrics, now we just set it up and forget it! Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

I couldn't say I dislike, but a comprehensive product like this should have it's own event analytics features. We shouldn't have to send data to other analytics platforms, it's already there! Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

Tracking events of our users, creating dynamic segments based on users' activities and sending them personalized feedback and campaign notifications without hardcoding anything. Review collected by and hosted on G2.com.

What do you like best about Customer.io?

As a company with over 2,400 employees, we value our customers and always want to improve the way we communicate and nurture our customer relationships. One focal point that made us choose Customer.io was its ability to remain simplistic while giving us the ability and tools to scale as we grow year-over-year. The search for the right platform for us wasn't easy; there were several calls with competitors that just didn't speak to our needs for multiple reasons, especially email platform usability, security, and infrastructure.

When we chose Customer.io, we were almost immediately able to increase our deliverability and solve several longstanding issues that increased our reach across all our stores. Even as we enter the new year, we're still discovering new ways we can increase our productivity, reduce our team's workload, and continue to scale our business. Customer.io truly puts the power back into multi-channel messaging to create a cohesive environment that our customers can feel engaged in. Two million customers strong! Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

I think Customer.io should show more support for their smaller customer base. Yes, we are a big company, but extending some of these great features to smaller customers would push the platform even further. Specifically, chat support and utilizing collections in workflows. Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

Customer.io allows us to build robust marketing automations to consistently reach our customer base and launch multi-channel campaigns. It also allows us to develop 1-to-1 relationships with each customer based on their engagements and interests. Review collected by and hosted on G2.com.

What do you like best about Customer.io?

I think customer.io has a clean UI and it's pretty intuitive. But the thing I think is the best is their customer support. We have an amazing rep who is knowledgeable, always available and supportive. Their chat support is also great - easy to get, rarely any wait times, and consistent and timely follow-up. Across the board, one of the best support teams I've worked with. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

There are always small things when it comes to functionality that you wish you had, but they are probably not as applicable to other businesses or do not fit into the core c.io business strategy so not on the roadmap for product development. There is nothing major. Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

c.io is addressing our need to communicate with our customers and leads through segmented data-driven personalized communications. Review collected by and hosted on G2.com.

What do you like best about Customer.io?

I've been using the tool for a year and half now, I use it daily and the platform seems to be more intuitive than ever. I've been able to pitch better use cases for the tool at my organization and implement them with remarkable results. The control I've had over the larger picture as well as granular details is quite useful. The tech support has been a savior and their feature rollouts have been easy to follow. Beyond everything, as a marketer, I think the company as a brand does amazing work - it applies B2C principles of communication seamlessly to an otherwise boring B2B category. It's been a pleasure. I Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

I was disappointed when they changed their 'human' chat support to a bot - it is surely faster but it doesn't have the immediate option of someone being able to access my workspace remotely and helping me through something. The capabilities are endless so sometimes it is difficult to pick which new integration to dive into. Review collected by and hosted on G2.com.

What problems is Customer.io solving and how is that benefiting you?

As an organization, we've moved from Pardot into Customer.io so I have been able to better tailor our messaging and automate more of our processes. It's made a huge difference in how we engage with our audience as we can create more personalized campaigns, track customer behavior, and really dive deep into segmentation. The flexibility and ease of use have made my job much easier, and it's helping us connect with our users in a more meaningful way, which has led to better engagement and results. The fact that it isn't as tedious-seeming as SalesForce makes the overall experience quite pleasant. Review collected by and hosted on G2.com.
