Even though at first it might have a longer learning curve (because there are several functionalities we can make use of), I think it compensates having the ability to create complex workflows for email campaigns: there are several functionalities available, and we're always able to create the flows we ideate. I particularly like the “draft” option to test campaigns I've just set up and made live and that we're able to integrate with other data platforms, that enrich our trigger and filter capabilities.Excellent customer support. Even though we're not on the Premium plan, any of the queries we submit are answered within 24 hours and have detailed explanations or workarounds for the issues presented.They also have interesting webinars from time to time, with quite specific topics and tips.

Unfortunately, we're unable to move a contact manually within a workflow; which is particularly important for exceptional cases that we might want to override the rules because of a human or sync error. Another feature I'd like to have (but also seems to be missing from most similar tools), is the ability to have custom reports – though I wouldn't need this very often, thus it's not a dealbreaker at this point.The pricing is somewhat expensive, and we're not able to temporarily downgrade the plan (if by any chance our business has a seasonality).

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 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.

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.

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! :)

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.

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.

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.

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.

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.

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

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.

Its been so easy, [purchase, set up and launching I cant complain at all.

I like you can easily integrate with other platforms, with the open API makes it so very easy!

Nothing! It has just been amazing, I love this software

Everything is perfect

I like going to customer.io to crease sub segment of our users. The ability to filter user by attributes is very simple to use.

User filtering options can be more flexible

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

I've been using CIO for an year and a half, and from the start I liked their clean UI and how visible everything is. Customer.io lets me be very creative when it comes to engaging people with emails. Their approach based on users behavior is fantastic and can create a lot of scenarios which would be hard to do with other tools. I can create really long flows that stretch for months, have each email in there be triggered or filter out users on the fly. Did I mention the awesome A/B tests? Very helpful support team as well.

I'd like an easier way to delete user profiles instead of mailing support to delete in bulk. Also, would love to have a way to download an automated report for all the campaigns instead of doing it manually.

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.

I'm kn the startup plan, and this product is an absolute requirement in my toolbelt. If Customer.io went away I would ne lost .

Nothing. This product is completely amazing lol.

The experience has been great

1. Ability to customise communications using events and segments2. Responsive customer support

1. Very expensive for a start up2. Flow for within branches still need optimisation as users can not move from one branch to another if their status/attributes changes.

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

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.

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.

I like how the drip campaigns are very simple to set up and implement. The segmentation tool helps to identify which customers to put into these campaigns and when they should exit the campaign.

I like how easy it is to build emails, though there could be better design/templates for this. Additionally, setting up segments might be confusing for someone without a data background, which I have.

Possible to make super complex flows. Pretty much replaces doing everything custom in our backend.

Nothing to dislike really. A bit complicated to use for new users, but probably because it's so powerful.

The features and capabilities offered are great for the price. Strong Customer Service as well.

Sometimes our/their APIs don't push data correctly.

The ease of use and the flexibility it provides

Sometimes the integration process can be a bit cumbersome.

Email marketing has become a big thing now, where people find it more aesthetic and relevant due to it's reach on a genuine platform. Customer.io plays a crucial I'm providing a messaging platform for all such sectors to work on.

UI/UX plays a crucial role in for any customer to find a platform easily usable and making it more interactive, so here is where it can improve it's quality

When we build new apps or startup prototypes for clients, Customer.io is one of the most reliable tools in our stack. It makes customer communication SO easy and intuitive, allowing you to easily group customers into segments, trigger communications based on specific events, etc. The API is easy to use too, and makes it really easy to integrate with your app at a deep level. I couldn't imagine life without it!

The only real complaint is pricing. If you are bootstrapping and don't have a ton of money to spend, it can be pretty prohibitive.

Very easy to integrate with our platform. It has changed the way we look at customer engagement.

Customer profiles can be difficult to manually add and remove from marketing segments

We use customer.io for automatic and personalized triggers and this tool is amazing.

Workflow is easy to configure and very powerful for automation. You can configure the tool in such a way emails are automatically triggered whenever it notices a particular behavior. A/B Testing feature is really cool.

Integrating with other APIs is complex.

Customer.io makes it so easy to create professional emails. I was able to jump in with very little training because the email-building features are so intuitive.

I've only been using Customer.io for about 3 months. So far I haven't run into anything that I feel needs improvement.
