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.

Extremely positive

The UI/UX is very smooth and clean, and customer service is spectacular. As someone who has used many ESPs, it's very important to me that I can work smoothly without interruptions. In my career, CIO stands alone in UI/UX among competitors. Our account representative is always available for help and consultations, and is always bringing value to our relationship.

It would be nice if there was an out-of-the-box solution for opt-in forms, but it integrates well with our third party app so this isn't a big deal. What they lack here is completely made up for in the quality of their platform and their integrations

I'm happy with the tool and feel confident sending transactional emails or marketing newsletters.

The platform has a steep learning curve, but once you get past that phase, it's truly powerful. Things that seemed impossible with other email clients are feasible with Customer.io. The drag and drop editor is also much better and runs much more smoothly than others I've used.

I'd say the biggest con is that it's a bit pricey. It can also be a bit overwhelming at first because there are so many features, but you just have to push through the learning curve.

It's great and does everything we need it to!

The automations are the best part of the software. We can easily create any type of campaign and manipulate it for our needs.

It would be cool if we could just duplicate a workspace entirely with all the segments and campaigns instead of recreating everything. Another thing that would be cool is being able to do a dynamic wait. Or have a queue type of system built-in for webhooks.

The UI/UX is really great and intuitive. It comes with a lot of features and different channels. It can be used by many different types of people, from not knowing how to code at all, to more advanced users. Enabling complex possibilities.

Setting up our dedicated preference center required quite some time and resources. Plus it did break native campaign tracking as well as the native unsubscribe button. But they are coming with a new feature on this side really soon.The second pain is focused on data analysis. There is quite some interesting data point, but it can quickly get tough when you try to extract specific behavior or data point. They know about it and are working also on this big part of the product.

We have been using Customer.io for nearly three months, and it has revolutionized the way our SaaS business communicates with its customers. From multi-part onboarding of new customers to re-stimulation of lapsed users to announcements of new features, Customer.io has been a dream come true for our subscription business. Building a sequence ("workflow") of emails, triggered by a particular event (like SIGN-UP or UPGRADE or CANCELLATION) is a snap. And applying it to individual customer segments is easy, though you'd better brush up on your logic (AND/OR/NOT etc.) before you construct a more exotic segment. So, too, is the ease of constructing one-time mailings ("newsletters") to an entire group of customers meeting a certain set of criteria. Once the segments are defined, sending newsletters is quite straightforward. In this regard, Customer.io runs circles around MailChimp, which we used to use for this purpose. Integration with a software product like ours is quite straightforward, and Customer.io offers a nice API for updating customer profiles and posting events for those customers. Customer.io currently falls short in the content creation department. Its text editor doesn't measure up to the rest of the application, and requires quite a bit of hand-manipulation of HTML to get newsletters and emails looking just the way you'd like them. Getting email text to wrap around a right-justified image, for example, requires knowledge of and hand-coding in HTML. And even then, the HTML produced by the text editor is not clean. Missing, too, are functions like being able to duplicate a workflow in order to launch a slightly different communication flow to a different customer segment. Onboarding customers to two different product tiers, for example, requires that the entire workflow be created from scratch for each segment, rather than allowing the user to duplicate the workflow and make changes to suit the second segment. Those shortcomings aside, Customer.io is a tool that shows a great deal of promise for any company that wants to communicate on a regular basis with its customers, especially when those communications need to be sequenced over a customer lifecycle. For a recurring-revenue business, where ongoing communication is key to retention and referral, a tool like Customer.io is essential to success.

- Customer data base is very flexible, and easy to keep up to date via API - Very powerful segmentation tool that can use customer profile fields, events, and even interaction with email to segment customers for subsequent communication - Easy, intuitive construction and management of triggered, multi-part communications workflows - Attractive visual reporting of emails sent, opened, clicked - Reasonably priced, automatic scaling of pricing based on actual volume used (emails, customer profiles) - Built-in A/B testing of email copy

- Text editor lacks power features; requires HTML in order to optimize emails - Minimal pre-packaged layouts; layout design requires knowledge of CSS - Lack of workflow cloning or replication creates unnecessary work

Great tool. Not made for beginners but if you are willing to spend time on masterising, I highly recommend. I have been using it in several companies for the past 5 years.

- Easy to use - Integrate with Segment - Constant updates

- Could be complicated if it's your first Marketing Automation tool but you get the hand of it quickly

Customer.io is an excellent email marketing platform. I made the switch from a lesser-known (and cheaper) platform that I had been using for a few years. I can clearly see the difference now, and I'm happy to pay more for the ability to engage my customers more effectively and access a wider range of marketing features, all in one place.

Customer.io is not yet the ideal platform for my projects. One limitation, for instance, is its restricted template language.It also lacks the ability to filter and count incoming events and dynamically insert these values into emails.

A highly efficient setup for automating emails to our customers. This individualized attention has vastly improved our relationship with our customers. They feel front and center and we save hours of time!

This software has been easy to use for setting up customer emails that are specifically targeted to their individual needs. Conversion tracking and other metrics for analyzing customer behavior are helpful for our team and its insights into what our customers want throughout their lifecycle journey. This software streamlines the process that would take hours upon hours of tedious work. This is a highly efficient tool to solve complex problems.

I think that one of the cons would be pricing. If pricing wasn't as steep for larger customer lists, this platform would be preferable.

customer.io is easy to use and very versatile. It has met all of our email marketing needs for both our web and mobile app.

customer.io has a bit of a learning curve at first with some of the advanced/pro features like customizing email messages, deploying api triggered messages, etc.... but the interface is very easy to use and when I had questions I could always get a hold of support for help.

Easy to use! SSO is great. Very user friendly and support is very kind.

The HIPAA version was very expensive to sign for a small start up

Overall great email and push notification automation software, that constantly develops.

Customer.io is great since it easily allows you to set up and automate promotional emails , but also allows to run transactional emails at the same time. This is a huge advantage over most email automation products, b/c you can trigger a promotional email without interfering with your system emails.

Unlike Pardot or Marketo, Customer.io doesn't have a solid automation builder. The builder is nice, but you can never see the tree of emails in a flow chart. It can easily confuse the user as you have to have a third-party software to organize the set up. It's highly recommended to put one full-time employee behind it.

Despite never using Customer.io before, it was relatively easy to learn. Some features have a learning curve for sure, but I'm always able to figure them out plus the support from our CSM (shout out to [sensitive content hidden]!) and the deliverability team has been amazing. So grateful for them!

I'd love to have more customization in the email builder, and the ability to add a drop-down question in the subscription preferences center.

I am able to provide my marketing team with the ability to send complicated emails, segmented across our customer base, with customized attributes.

As a developer, working with the API is easy, predictable, and maintainable. The product supports complicated email workflows with customer-level attributes. This isn't your father's mail-merge. This is email for the 22nd century.

The lack of a WYSIWYG editor for my marketing counterparts (tho I hear rumors this is coming) and event-based filters in my workflows.

We were looking for a solution that could improve our customer success goals and reduce churn. Customer.io delivers as the go-to platform in this category.

We were using an email service provider and a Figma design file to manage and sync our customer messaging flows. We needed a proper solution, so we compared a lot of companies, and Customer.io seemed to be the most reputable.

The hurdle to learn and use the platform was a bit high, and there were areas of UX that could have used some improvement. But at the end, the platform is so quick and now as we are used to it, it does exactly what we need it to do.

Honestly -- they care so much about their customers. They listen to feedback and get back to you on issues or questions so quickly. Highly recommend their product.

- Easy to navigate - Newsletters and campaigns

- None yet -- maybe that I can't attach a file?

Customer.io is a powerful tool that offers many benefits for businesses looking to automate and personalize their customer communication.

One of the biggest pros of using Customer.io is the ease with which you can set up and automate email campaigns. The platform offers a drag-and-drop interface that makes it easy to create customized campaigns without needing to know how to code. Additionally, Customer.io offers a variety of templates to choose from, which can save time and simplify the process.Another pro of using Customer.io is the level of customization available. Businesses can create highly specific customer segments based on behavior, demographics, and other factors. This allows businesses to target their messages to specific groups of customers and tailor their campaigns accordingly.

One of the main issues is the learning curve. While the platform is relatively easy to use, there is still a lot to learn in order to make the most of its features. Additionally, the pricing can be steep for small businesses, which could make it less accessible.Another potential downside is that Customer.io is focused primarily on email marketing, which means that businesses may need to use additional tools to cover other communication channels like social media or SMS.

- really really good for customer journey communication, easy to build trigger based automation.- easy to integrate with many marketing, CRM & Data Tools- automatize SMS, Email, Push notification- highly functional for Campaign automation

- User interface bit tricky to get used too with it

Great to build and send automated campaigns. Can improve its usability in sending bulk emails.

It is a really detailed tool. Found it very useful to send out multiple emails in a flow. Allows you to create a workflow through which you can plan the email sent to customers. You can even put conditions to send it to specific users. Provides a number of integration options with other tools to interconnect the entire process.

As I mainly use it to build and send emails. The creating emails part does get tedious at times. The drag and drop builder isn't the easiest to use. It also has a limited amount of templates

Customer.io has been a life saver. It has been a huge relief knowing our customers are getting the correct information.

There are not many customization options. It is also limited to users that has large customer bases.

In using customer.io it is easy to use and setup for your business. It has a wide range of features and easy to use templates.

The lack of native integrations to CRMs is a big negative but they do work with integration tools like Zapier.
