Talking from the perspective of a marketer at a SaaS with average. 50K email subscribers, Customer IO has been an excellent tool for us. Our requirements include sending users newsletters, marketing emails, and transactional emails, running lead-nurturing campaigns, and more. For a comprehensive use case like ours, CustomerIO is great. While it also has a learning curve, when you have such requirements, it’s worth it. I don’t think CustomerIO is the best fit if you have basic requirements like only weekly newsletter emails.
I would say the greatest strength of Kustomer is its flexibility. In the hands of a skilled admin, it can be adapted to tons and tons of different use cases. I've been able to make custom displays for different groups of agents, produce complex cross sections of users, draw interesting data relationships combining marketing contacts and customer-initiated contacts. For example, there's really no other data source in our company which could tell you which users received a specific promo code and checked out with it, received their delivery within 14 days and then can related that to the number of times they contacted us about using our product. At the intersection of communication, marketing, data, and relationship-management, Kustomer shines at the center. I would say it falls short when you are trying to coordinate multiple "side conversations" with multiple sources to resolve an issue. This is a tough task for any type of platform, but if you're maintaining 3 different email chains with a 3PL partner, the customer, and a separate internal conversation, it would be confusing anyway!
Managing users, attributes and events. You are easily able to modify any user, based on their ID, and add or remove attributes, assign events to them. That makes it very easy to segment later and to assign them to several campaigns based on behavior. Just a warning: this integration isn't so easy (at least it wasn't for us).
Creating workflows of campaigns is very easy. You can quickly create behavioral campaigns based on attributes, segments and add elements to the workflow. You can send an email, then wait, then send another, then exit the campaign if they converted, etc. The workflow is easy to configure and very powerful for automation.
We don't use many email templates (we make them in MJML) but it's very easy to add senders, to change templates and in general to test designs.
Deliverability works very well, at least for us. It sends emails pretty fast and without issues.
Exporting is very quick and easy. Importing wasn't a feature until recently, but it works well too.
Seeing activity it's also useful. In general, logs are awesome (be it of a customer, of activity on the site, email sends, etc.).
We don't use environments, but it might be very useful for a bigger company.
All customer data (past orders, communication with customer service, rewards account data) is in one place. This helps agents avoid confusion and reduces the number of tabs they need to open.
The Knowledge Base (or K Base) is very helpful. Any time we roll out a new policy or have a limited-time promotion, we can add all the relevant information and worksheets there for the convenience of the agents. That way they can stay in a chat while looking up the answer to a question.
We can seamlessly move from chat into email if the customer leaves or the queue times are too long. All the interactions will stay on the customer profile page, so they are kept up to date.
For our team, the feature that defaults all notes to begin in "done" status is difficult. Throughout each day we need to have notes open and assigned back and forth to different teams, and we have to remember to manually "open" each note. There is too much room for human error with this setting, and it is easy for important notes to be missed if a user forgets to open the note.
Similarly, it can be hard to remember to assign emails/notes to a particular team in addition to a user. We almost exclusively work out of team inboxes, and if someone on Care writes an email to a customer, the email will automatically be "done" when it is created, and it will be assigned to the user who wrote it, but not also to the user's team. There are instances where an email needs to be snoozed for several days/hours with further action needed, and unless the user remembers to assign the email to their team it may "awake" from the snooze and not be visible to anyone except the user who created it. Similarly to my first comment, this leaves a lot of room for human error and is not very intuitive.
Personally, I do not love that all tickets/emails/notes are jumbled together in the same inbox. While this gives visibility to everything on the "to do" list at the same time, it can be visually overwhelming. We have created unique folders for certain types of projects or categories of work, but have experienced tech glitches or just the awkwardness of another step to manually read the note, determine what type of category it is, and then manually assign it to another folder. Would love to have things auto-sort and take out this manual lift.
I love the idea of the autopilot setting, but we have not been able to use this for our work because it sorts items based on time, and not based on priority. In our line of work, we may have an urgent situation arise that needs attention before an email that was sent in 60 minutes ago. The autopilot feature would push the email to my associates sooner than it would the urgent situation from 5 minutes ago. Due to this, we manually monitor inboxes and assign work to ourselves and others.
Everything was pretty intuitive to use if you've used an ESP before. The only thing that was confusing is Campaigns vs Newsletters - some of their naming conventions aren't straightforward. But their docs, support and AI agents are all super solid.
There is a learning curve, but it is more than worth it, especially to have a dedicated resource pointed at Kustomer and any other software it interacts with. The basic implementation is useful, and powerful - certainly a MASSIVE upgrade over taking care of your customers in an email inbox or shuffling between multiple windows and applications! It is also set up really well to grow and reconfigure with your business. I'm a big fan.
My experience with their support team has always been great. Very quick to respond, have an online chat, and are very helpful. They helped me resolve any issues I've had every time in a professional and knowledgeable manner. We've now switched to another tool, and I can't even compare the service level we get there to customer.io
I did not reach out to Kustomer support when we had an issue. Still, whenever we provide feedback to our manager regarding what can improve based on our experience using Kustomer, our manager always comments that Kustomer support always replies with some positive feedback based on our suggestions.
Customer.io was really the first pure, full-featured drip email program on the market and as far as I know, it's still the simplest and best overall for that specific function. SendGrid has also added drip campaign features, but I would seriously evaluate Customer.io against any other drip email provider because they really have all the key elements you need to make it work.
Apps like Intercom, Zendesk, and Gorgios all treat customer inquiries as tickets, just tracking that one issue or interaction with a customer. Kustomer treats each customer as an individual, which allows us to provide top-notch customer service. Customers love that we're able to be more conversational and informal, while still solving their issues quickly. It also helps us build relationships with customers and increases repeat orders.
Positive impact on the sales side. I'm not sure about the specific ROI (you have to include the designer and the time it takes to set up) but you certainly get back the investment in a few months, once you are able to scale your email marketing.
Customer experience is way better by having more segmented, contextual and accurate messages sent to them.
Integration is costly and it will take several days or weeks to be fully achieved. Expect to invest some money on this.
We’re getting so much positive feedback — which is not something you traditionally associate with a customer care team — because we’re making it effortless for customers to deliver both positive and negative feedback, and we can now resolve the bad feedback really really quickly.
Primarily from our increased efficiency with Kustomer, we’ve seen a significant reduction of $3 to $4 for every cost per contact.
