I've been using Customer.io for almost two years and couldn't be happier with our experience! It was super easy to transition from our previous email client and integrate and connect with our other software. It's been an important piece of our marketing strategy and has helped us generate upsells and new leads.

Pros

I've worked in many email marketing tools over the years and Customer.io is by far the easiest to use for every member on our marketing team! The drag and drop tool has really helped us achieve the same brand look across every email we send - and it's easy enough that even our copywriters can create emails. No designers or developers needed!

Cons

The only limitation is that I wish the dashboard and interface was a bit more user friendly. I feel like the image library is buried. I feel like there's so many impressive C.io features get hidden. I also wish you set your "Email Settings" in your Team Profile and those settings could be applied to every email instead of manually inputting them each time.

Alternatives Considered

HubSpot Marketing Hub, Mailchimp and Intercom

Reasons for Choosing Customer.io

We were not happy with the usability of Intercom for our Marketing Emails. The functionality of C.io was seamless and so easy to use for our entire team. As a designer, I was able to create a library of row designs tailored to our brand library so now anyone on the team can throw together a branded, well-designed email. C.io has made my job SO much easier!

Reviewed on 2023/01/05

Pros

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.

Cons

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 are mainly using C.io for lead nurturing purposes. We are quite confident with the fact they will improve their product with better reporting features.

Pros

I've tried many marketing automation tools and Customer.io is clearly making a difference in terms of UX, documentation, and customer support!

Cons

It can be quite complex sometimes according to your needs but thanks to their great UX, documentation, and support team, you'll find solutions. There are some missing features (eg. cohort analysis) but hopefully, they are working on it.

I've tried many marketing automation tools and this hits the spot in terms of what a tech-savvy non-developer can do. There's a fine line between an eye-candy platform that scores low on customization and a fully fledged tool that requires constant support from a developer. Customer.io walks that line gracefully, allowing me to control onboarding and loyalty processes and much more.

Pros

I like that I have yet to hit its limitations. Usually if a feature isn't readily available, the platform is open enough for me to find a workaround that gets the job done.

Kudos for customer support, a real win! :)

Cons

It could use more or better filtering and search options, as the segments, campaigns and attributes can turn into chaos if multiple people use it for different purposes.

The learning curve was a bit steep. Except for the quite useful knowledge base and great customer support, I would have enjoyed some video tutorials/onboarding experience.

Pros

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

Cons

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.

Reviewed on 2022/06/25

Pros

Customer.io is very catered towards SAAS products like ours. Very easy to integrate our data sources like Segment, and simple to get attributes and events. Perfect for running onboarding campaign or lead nurturing campaign. It's the most simple to use product compared to everything else I've tried.

Dashboard is also very fast despite a lot of data. Not clunky at all. This lets me create and send campaigns in a much shorter time.

Cons

Quite a bit of jargons in the dashboard, which can be a little confusing. It'll be great if there's more explanation on certain features. Easy to overlook some of their outstanding features because they are hidden.

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

Pros

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.

Cons

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.

Great Customer Email Tool - Content Creation Needs Improvement

Reviewed on 2016/03/22

We have been using Customer.io for nearly three months, and it has revolutionized the way our SaaS...

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.

Pros

- 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

Cons

- 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

Overall, very happy with the user experience. It’s saved me a lot of time in developing our newsletter.

Pros

I love using Customer.io for our weekly newsletters because it allows me to replicate the same format each week. This saves me time each week because I can just make individual tweaks to content each time, rather than having to redo the entire process. I also appreciate the metrics on open and click rate, to know what content sparks our audience’s attention and what doesn’t hit so strongly.

Cons

I don’t like that it is difficult to copy a message from one “workspaces” to the next. I wish there was a possibility to duplicate a template across workspaces without having to recreate the whole thing. We use different workspaces to separate different audiences, but often want to send them similar emails.

Pros

Customer.IO has allowed me and my company to feel confident that the correct information is being sent to the people who need it the most, our customers. The ability to view all emails that have been sent and to ensure they were received by the customer is a huge benefit to us. being able to see if a email was suppressed or bounce give the ability to ensure you can deal with the issue in a timely manner and get the info into the right peoples hands. it has also assisted us in dealing with difficult customers that claim they never received a email, however the application allowed us to show the customer that no only did they receive it they opened it!

Cons

the only negative i could see is that the application only allows you to send 50 emails at a time and for a large customer base this makes it more time consuming.

Pros

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.

Cons

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.
