Pricing doesn't work

Customerio is generally fine, but the pricing structure doesn't work for us. Ordinarily, in this situation, we would just go with a different company, but we haven't found one that makes sense. They got us in on their startup program, but that is just a bandaid on their pricing model.

Review of Customer.io from avid user

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.

Customer support

Functionality

Pros:

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.

Cons:

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.

Reasons for choosing Customer.io

This was recommended by a colleague who had used it previously, and we bought in right away.

Reasons for switching to Customer.io

Too many different little tools when everything is built into Customer.io

Functionality

Pros:

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.

Cons:

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

Reasons for switching to Customer.io

While we're mainly an e-commerce company, we also have a mobile app that is really important in the user journey. Klaviyo worked well for ecomm-specific engagements and tracking but wasn't built to support to in-depth customer tracking we needed from our app. We switched to Customer.io because it was a cost-effective option that allowed us to track both transactional events as well as user behaviours within our app and marketing site.

Ease of use

Customer support

Functionality

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.

Reasons for choosing Customer.io

The core product strength, the great UX, a comprehensive and competitive pricing

Functionality

Pros:

It's very easy to use and does 90% of what you'd need to automate your marketing.

Cons:

Some of the UI choices over time have become worst, like elements covering crucial elements (eg. minimap when editing an email), and their push to become more of a CDP than a marketing software has made the platform more cluttered for those who, like me, want to use it for marketing automation. Lastly, but possibly most importantly, the fact that we still can't DUPLICATE a campaign is absurd. Having to re-create campaign settings each time is such a time waste, for a seemingly obvious (And simple) feature.

Reasons for choosing Customer.io

Price and ease-of-use.

Reasons for switching to Customer.io

Customer.io is much more capable of managing multi-channel campaigns, with complex segmentation.

One of the best email marketing tools I've used!

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.

Customer support

Functionality

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.

Reasons for choosing Customer.io

We had various demo calls with the alternative products listed above and C.io stood out to our entire team. The ease of use was unmatched. It was exactly the platform we had been looking for.

Reasons for switching to 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!

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.

Reasons for choosing Customer.io

It auto-populated the customer attributes when we linked up Segment. It also had better logic control.
