Customer.io is one of my favorite tools at work, so easy to use that I don't even have to teach new people on my team on how to use it, they just do. I check it every day and use it as the main tool in communicating with our clients about new feature releases, new products, important changes in our software, customer marketing etc. Also it's our main tool for onboarding new users through email campaigns that are very easy to setup, with a lot of functionalities that helps us filtering the customers and offering a personalized experience. I really recommend it

I really like how easy it is to setup an email campaign and automate it according to users different attributes. We have a lot of onboarding campaigns going on in all languages and it is the best software we have with this kind of funcionality. Also, broadcasts are very simple to create and easy to track. The UX/UI of the platform is perfect, definitely the best one we have among the e-mail senders we use.

The template creation is very limited, forcing us to use other softwares and exporting the HTML code to customer.io. Also, the contact database is kind of messy, not very easy to find people, organizing contacts or filtering them.

Customer.io has evolved so much since I started using it! In the beginning, we had to use a lot of workarounds like sending leads via Zapier but they've made huge quality-of-life improvements. We can either use our data connectors to facilitate lead management but they also have a form connector that makes this process a breeze.I love how easily Customer.io connects to our existing data structure and makes it super easy to break down data silos across our suite of tools. The integrations are really easy to use!The campaign builder is super flexible and allows us to not only send marketing comms to our users but also to clean up data and use it to automate basic tasks within the platform. Emails are very easy to setup, especially with the ability to save rows and use snippets. This saves us time when creating new content. We also frequently use the display conditions for email as we have different offerings for users in Canada VS the US. This helps us really customize the content to fit the users' needs.

While Customer.io does offer SMS/mobile messaging, it would be great if they integrated with more companies so we had more options here.

I don’t find this product very easy to use but it’s one of the best so far I’ve used in the email automation space.

I liked that I could run my drip campaigns on this tool. The complexity of the drips could be managed.

It requires a dedicated developer which might not always be possible. There should be a few automated codes.

We love it. It surpasses all of the cheaper options and plugs into our product in a way more efficient way. I regularly recommend it to friends in similar sized businesses.

Functionality is really great. It is easy to use, and the flow of setting up campaigns and broadcasts makes perfect sense. I've used the drag and drop as well as uploaded HTML into different campaigns. Testing is good, the omni channel approach all in one section is super helpful. It's built like a marketing manager had a say but a developer and engineer understood all the actual requirements.

Analytics and the reporting, as mentioned previously. The conversion rate should be more adjustable to show people who entered journeys and converted vs just how many emails were sent and conversions. It makes changing up campaigns a little tougher, but still doable with exports and managing the analytics manually.

The customer success and support team at CustomerIO have been a massive factor in my experience. I cannot express my appreciation enough. They are prompt, amiable, and always willing to go the extra mile whenever I reach out to them. I really value the CSM assigned to our account. He has not only taught me how to use Customer.io, but he's also doubled as a strategic partner in helping me bring my ideas to life through Customer.io.

I find the product to be user-friendly and enjoyable. The campaign builder is my favorite feature as it allows me to create intricate journey flows with ease. The 'wait until' action block has been a game-changer for me as it has minimized the need for engineering resources.

I've been using Customer.io for 6 months now and honestly, I don't have any complaints. Seems like for every issue I've had, the support team is dedicated to unblocking me. There are always ways to improve a product, but in terms of important game-changing features, they really thought of everything.
